-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2015:093 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : apache Date : March 28, 2015 Affected: Business Server 2.0 _______________________________________________________________________ Problem Description: Updated apache packages fix security vulnerabilities: Apache HTTPD before 2.4.9 was vulnerable to a denial of service in mod_dav when handling DAV_WRITE requests (CVE-2013-6438). Apache HTTPD before 2.4.9 was vulnerable to a denial of service when logging cookies (CVE-2014-0098). A race condition flaw, leading to heap-based buffer overflows, was found in the mod_status httpd module. A remote attacker able to access a status page served by mod_status on a server using a threaded Multi-Processing Module (MPM) could send a specially crafted request that would cause the httpd child process to crash or, possibly, allow the attacker to execute arbitrary code with the privileges of the apache user (CVE-2014-0226). A denial of service flaw was found in the mod_proxy httpd module. A remote attacker could send a specially crafted request to a server configured as a reverse proxy using a threaded Multi-Processing Modules (MPM) that would cause the httpd child process to crash (CVE-2014-0117). A denial of service flaw was found in the way httpd's mod_deflate module handled request body decompression (configured via the DEFLATE input filter). A remote attacker able to send a request whose body would be decompressed could use this flaw to consume an excessive amount of system memory and CPU on the target system (CVE-2014-0118). A denial of service flaw was found in the way httpd's mod_cgid module executed CGI scripts that did not read data from the standard input. A remote attacker could submit a specially crafted request that would cause the httpd child process to hang indefinitely (CVE-2014-0231). A NULL pointer dereference flaw was found in the way the mod_cache httpd module handled Content-Type headers. A malicious HTTP server could cause the httpd child process to crash when the Apache HTTP server was configured to proxy to a server with caching enabled (CVE-2014-3581). mod_lua.c in the mod_lua module in the Apache HTTP Server through 2.4.10 does not support an httpd configuration in which the same Lua authorization provider is used with different arguments within different contexts, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging multiple Require directives, as demonstrated by a configuration that specifies authorization for one group to access a certain directory, and authorization for a second group to access a second directory (CVE-2014-8109). In the mod_lua module in the Apache HTTP Server through 2.4.10, a maliciously crafted websockets PING after a script calls r:wsupgrade() can cause a child process crash (CVE-2015-0228). A flaw was found in the way httpd handled HTTP Trailer headers when processing requests using chunked encoding. A malicious client could use Trailer headers to set additional HTTP headers after header processing was performed by other modules. This could, for example, lead to a bypass of header restrictions defined with mod_headers (CVE-2013-5704). Note: With this update, httpd has been modified to not merge HTTP Trailer headers with other HTTP request headers. A newly introduced configuration directive MergeTrailers can be used to re-enable the old method of processing Trailer headers, which also re-introduces the aforementioned flaw. This update also fixes the following bug: Prior to this update, the mod_proxy_wstunnel module failed to set up an SSL connection when configured to use a back end server using the wss: URL scheme, causing proxied connections to fail. In these updated packages, SSL is used when proxying to wss: back end servers (rhbz#1141950). _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-6438 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0098 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0117 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0118 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0226 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0231 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3581 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-5704 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-8109 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0228 http://advisories.mageia.org/MGASA-2014-0135.html http://advisories.mageia.org/MGASA-2014-0305.html http://advisories.mageia.org/MGASA-2014-0527.html http://advisories.mageia.org/MGASA-2015-0011.html http://advisories.mageia.org/MGASA-2015-0099.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 2/X86_64: 8c0fc93f8b18e8d40190ef9084f2d583 mbs2/x86_64/apache-2.4.12-1.mbs2.x86_64.rpm 6c90dd9f12f65e54ff131b0f4f2d04ee mbs2/x86_64/apache-devel-2.4.12-1.mbs2.x86_64.rpm 8b58ae3f9e57e02ff94a70de04ec8f23 mbs2/x86_64/apache-doc-2.4.12-1.mbs2.noarch.rpm fefc0679674332198f1b42d5a0240351 mbs2/x86_64/apache-htcacheclean-2.4.12-1.mbs2.x86_64.rpm 22c39f085c7f81ba4186040aa20a79b4 mbs2/x86_64/apache-mod_cache-2.4.12-1.mbs2.x86_64.rpm d57f8944df9e0443ee3da9bdc2cb78d1 mbs2/x86_64/apache-mod_dav-2.4.12-1.mbs2.x86_64.rpm 7a0e6435e3aaa22e6453dca56c47abb3 mbs2/x86_64/apache-mod_dbd-2.4.12-1.mbs2.x86_64.rpm 30c9610763c492d3c5526e5625128aa8 mbs2/x86_64/apache-mod_ldap-2.4.12-1.mbs2.x86_64.rpm cdba1369c7b8dd017cf9790076bf0e15 mbs2/x86_64/apache-mod_proxy-2.4.12-1.mbs2.x86_64.rpm 4c4e73ac608bf820a87f27d00148f265 mbs2/x86_64/apache-mod_proxy_html-2.4.12-1.mbs2.x86_64.rpm 3103f59239d49810b16207502f271b8a mbs2/x86_64/apache-mod_session-2.4.12-1.mbs2.x86_64.rpm 2ef0b90590b36ca85c7103ebd02ea64b mbs2/x86_64/apache-mod_ssl-2.4.12-1.mbs2.x86_64.rpm 2f2855321b6554e400ba5542da3027ea mbs2/x86_64/apache-mod_suexec-2.4.12-1.mbs2.x86_64.rpm b312e7cd14788b86c7088cc19473515c mbs2/x86_64/apache-mod_userdir-2.4.12-1.mbs2.x86_64.rpm dee3a16d2c36fed2716a3ed17addc1e1 mbs2/SRPMS/apache-2.4.12-1.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
