-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2015:062 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : openssl Date : March 27, 2015 Affected: Business Server 2.0 _______________________________________________________________________ Problem Description: Multiple vulnerabilities has been discovered and corrected in openssl: Race condition in the ssl3_read_bytes function in s3_pkt.c in OpenSSL through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, allows remote attackers to inject data across sessions or cause a denial of service (use-after-free and parsing error) via an SSL connection in a multithreaded environment (CVE-2010-5298). The Montgomery ladder implementation in OpenSSL through 1.0.0l does not ensure that certain swap operations have a constant-time behavior, which makes it easier for local users to obtain ECDSA nonces via a FLUSH+RELOAD cache side-channel attack (CVE-2014-0076). The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug (CVE-2014-0160). The dtls1_reassemble_fragment function in d1_both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly validate fragment lengths in DTLS ClientHello messages, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) via a long non-initial fragment (CVE-2014-0195). The do_ssl3_write function in s3_pkt.c in OpenSSL 1.x through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, does not properly manage a buffer pointer during certain recursive calls, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors that trigger an alert condition (CVE-2014-0198). The dtls1_get_message_fragment function in d1_both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote attackers to cause a denial of service (recursion and client crash) via a DTLS hello message in an invalid DTLS handshake (CVE-2014-0221). OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the CCS Injection vulnerability (CVE-2014-0224). The ssl3_send_client_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h, when an anonymous ECDH cipher suite is used, allows remote attackers to cause a denial of service (NULL pointer dereference and client crash) by triggering a NULL certificate value (CVE-2014-3470). Memory leak in d1_srtp.c in the DTLS SRTP extension in OpenSSL 1.0.1 before 1.0.1j allows remote attackers to cause a denial of service (memory consumption) via a crafted handshake message (CVE-2014-3513). The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the POODLE issue (CVE-2014-3566). Memory leak in the tls_decrypt_ticket function in t1_lib.c in OpenSSL before 0.9.8zc, 1.0.0 before 1.0.0o, and 1.0.1 before 1.0.1j allows remote attackers to cause a denial of service (memory consumption) via a crafted session ticket that triggers an integrity-check failure (CVE-2014-3567). The ssl23_get_client_hello function in s23_srvr.c in OpenSSL 0.9.8zc, 1.0.0o, and 1.0.1j does not properly handle attempts to use unsupported protocols, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an unexpected handshake, as demonstrated by an SSLv3 handshake to a no-ssl3 application with certain error handling. NOTE: this issue became relevant after the CVE-2014-3568 fix (CVE-2014-3569). The BN_sqr implementation in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not properly calculate the square of a BIGNUM value, which might make it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors, related to crypto/bn/asm/mips.pl, crypto/bn/asm/x86_64-gcc.c, and crypto/bn/bn_asm.c (CVE-2014-3570). OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted DTLS message that is processed with a different read operation for the handshake header than for the handshake body, related to the dtls1_get_record function in d1_pkt.c and the ssl3_read_n function in s3_pkt.c (CVE-2014-3571). The ssl3_get_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote SSL servers to conduct ECDHE-to-ECDH downgrade attacks and trigger a loss of forward secrecy by omitting the ServerKeyExchange message (CVE-2014-3572). OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not enforce certain constraints on certificate data, which allows remote attackers to defeat a fingerprint-based certificate-blacklist protection mechanism by including crafted data within a certificate's unsigned portion, related to crypto/asn1/a_verify.c, crypto/dsa/dsa_asn1.c, crypto/ecdsa/ecs_vrf.c, and crypto/x509/x_all.c (CVE-2014-8275). The ssl3_get_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote SSL servers to conduct RSA-to-EXPORT_RSA downgrade attacks and facilitate brute-force decryption by offering a weak ephemeral RSA key in a noncompliant role, related to the FREAK issue. NOTE: the scope of this CVE is only client code based on OpenSSL, not EXPORT_RSA issues associated with servers or other TLS implementations (CVE-2015-0204). The ssl3_get_cert_verify function in s3_srvr.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k accepts client authentication with a Diffie-Hellman (DH) certificate without requiring a CertificateVerify message, which allows remote attackers to obtain access without knowledge of a private key via crafted TLS Handshake Protocol traffic to a server that recognizes a Certification Authority with DH support (CVE-2015-0205). Memory leak in the dtls1_buffer_record function in d1_pkt.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k allows remote attackers to cause a denial of service (memory consumption) by sending many duplicate records for the next epoch, leading to failure of replay detection (CVE-2015-0206). Use-after-free vulnerability in the d2i_ECPrivateKey function in crypto/ec/ec_asn1.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a might allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a malformed Elliptic Curve (EC) private-key file that is improperly handled during import (CVE-2015-0209). The ASN1_TYPE_cmp function in crypto/asn1/a_type.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not properly perform boolean-type comparisons, which allows remote attackers to cause a denial of service (invalid read operation and application crash) via a crafted X.509 certificate to an endpoint that uses the certificate-verification feature (CVE-2015-0286). The ASN1_item_ex_d2i function in crypto/asn1/tasn_dec.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not reinitialize CHOICE and ADB data structures, which might allow attackers to cause a denial of service (invalid write operation and memory corruption) by leveraging an application that relies on ASN.1 structure reuse (CVE-2015-0287). The X509_to_X509_REQ function in crypto/x509/x509_req.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a might allow attackers to cause a denial of service (NULL pointer dereference and application crash) via an invalid certificate key (CVE-2015-0288). The PKCS#7 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not properly handle a lack of outer ContentInfo, which allows attackers to cause a denial of service (NULL pointer dereference and application crash) by leveraging an application that processes arbitrary PKCS#7 data and providing malformed data with ASN.1 encoding, related to crypto/pkcs7/pk7_doit.c and crypto/pkcs7/pk7_lib.c (CVE-2015-0289). The SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a allows remote attackers to cause a denial of service (s2_lib.c assertion failure and daemon exit) via a crafted CLIENT-MASTER-KEY message (CVE-2015-0293). The updated packages have been upgraded to the 1.0.1m version where these security flaws has been fixed. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-5298 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0076 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0160 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0195 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0198 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0221 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0224 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3470 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3513 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3566 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3567 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3569 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3570 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3571 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3572 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-8275 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0204 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0205 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0206 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0209 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0286 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0287 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0288 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0289 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0293 http://openssl.org/news/secadv_20150108.txt http://openssl.org/news/secadv_20150319.txt _______________________________________________________________________ Updated Packages: Mandriva Business Server 2/X86_64: 324a85f7e1165ab02881e44dbddaf599 mbs2/x86_64/lib64openssl1.0.0-1.0.1m-1.mbs2.x86_64.rpm 9c0bfb6ebd43cb6d81872abf71b4f85f mbs2/x86_64/lib64openssl-devel-1.0.1m-1.mbs2.x86_64.rpm 58df54e72ca7270210c7d8dd23df402b mbs2/x86_64/lib64openssl-engines1.0.0-1.0.1m-1.mbs2.x86_64.rpm b5313ffb5baaa65aea05eb05486d309a mbs2/x86_64/lib64openssl-static-devel-1.0.1m-1.mbs2.x86_64.rpm a9890ce4c33630cb9e00f3b2910dd784 mbs2/x86_64/openssl-1.0.1m-1.mbs2.x86_64.rpm 521297a5fe26e2de0c1222d8d03382d1 mbs2/SRPMS/openssl-1.0.1m-1.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
