-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2013:162 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : glibc Date : May 7, 2013 Affected: Enterprise Server 5.0 _______________________________________________________________________ Problem Description: Multiple vulnerabilities has been discovered and corrected in glibc: Integer overflow in the vfprintf function in stdio-common/vfprintf.c in glibc 2.14 and other versions allows context-dependent attackers to bypass the FORTIFY_SOURCE protection mechanism, conduct format string attacks, and write to arbitrary memory via a large number of arguments (CVE-2012-0864). Multiple errors in glibc's formatted printing functionality could allow an attacker to bypass FORTIFY_SOURCE protections and execute arbitrary code using a format string flaw in an application, even though these protections are expected to limit the impact of such flaws to an application abort (CVE-2012-3404, CVE-2012-3405, CVE-2012-3406). Multiple integer overflows in the (1) strtod, (2) strtof, (3) strtold, (4) strtod_l, and other unspecified related functions in stdlib in GNU C Library (aka glibc or libc6) 2.16 allow local users to cause a denial of service (application crash) and possibly execute arbitrary code via a long string, which triggers a stack-based buffer overflow (CVE-2012-3480). Buffer overflow in the extend_buffers function in the regular expression matcher (posix/regexec.c) in glibc, possibly 2.17 and earlier, allows context-dependent attackers to cause a denial of service (memory corruption and crash) via crafted multibyte characters (CVE-2013-0242). Stack-based buffer overflow in the getaddrinfo function in sysdeps/posix/getaddrinfo.c in GNU C Library (aka glibc or libc6) 2.17 and earlier allows remote attackers to cause a denial of service (crash) via a (1) hostname or (2) IP address that triggers a large number of domain conversion results (CVE-2013-1914). The updated packages have been patched to correct these issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-0864 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3404 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3405 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3406 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3480 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-0242 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-1914 _______________________________________________________________________ Updated Packages: Mandriva Enterprise Server 5: 87712654b036070964fb35385f398279 mes5/i586/glibc-2.8-1.20080520.5.9mnb2.i586.rpm eae25c5265ca4d2dab2dbf8b0450b6a5 mes5/i586/glibc-devel-2.8-1.20080520.5.9mnb2.i586.rpm 161b6288a6c2b13b299e6e7bdd699eae mes5/i586/glibc-doc-2.8-1.20080520.5.9mnb2.i586.rpm 08948383eccf30d736dfeaef53430eab mes5/i586/glibc-doc-pdf-2.8-1.20080520.5.9mnb2.i586.rpm 6f1ae9e591ed477bf56c7a3a1f7770be mes5/i586/glibc-i18ndata-2.8-1.20080520.5.9mnb2.i586.rpm 7beb9227ce1bbff7fe2848b5fad3b4ca mes5/i586/glibc-profile-2.8-1.20080520.5.9mnb2.i586.rpm 2451007d981f0314f675e7edd387003b mes5/i586/glibc-static-devel-2.8-1.20080520.5.9mnb2.i586.rpm e502bca8475975d9e2ce11eec93a10d2 mes5/i586/glibc-utils-2.8-1.20080520.5.9mnb2.i586.rpm 63241c1d294d1972b3d12206e4d38eb3 mes5/i586/nscd-2.8-1.20080520.5.9mnb2.i586.rpm 641edd61d4e607e9ccd4c5b3c8c790ac mes5/SRPMS/glibc-2.8-1.20080520.5.9mnb2.src.rpm Mandriva Enterprise Server 5/X86_64: 4c8e423f7ddc996f087e2fc304329b31 mes5/x86_64/glibc-2.8-1.20080520.5.9mnb2.x86_64.rpm e7d749c4c4ffdd3b8320ca4af0f1ed72 mes5/x86_64/glibc-devel-2.8-1.20080520.5.9mnb2.x86_64.rpm b5fb6b11ed3bb0ab2ad5168be6371457 mes5/x86_64/glibc-doc-2.8-1.20080520.5.9mnb2.x86_64.rpm f4392e4257f604bfb9baf17740e1cc7d mes5/x86_64/glibc-doc-pdf-2.8-1.20080520.5.9mnb2.x86_64.rpm 0cddcf4e1d98b60c892ca22741b08d11 mes5/x86_64/glibc-i18ndata-2.8-1.20080520.5.9mnb2.x86_64.rpm 301995478a3f943d5d0448cbc561e436 mes5/x86_64/glibc-profile-2.8-1.20080520.5.9mnb2.x86_64.rpm 395f0f667999586e57e296c6b867e616 mes5/x86_64/glibc-static-devel-2.8-1.20080520.5.9mnb2.x86_64.rpm 0595e256f6c1e2f2c7f94cca21fd4f35 mes5/x86_64/glibc-utils-2.8-1.20080520.5.9mnb2.x86_64.rpm ea48c2685180f722187736bc8a624e58 mes5/x86_64/nscd-2.8-1.20080520.5.9mnb2.x86_64.rpm 641edd61d4e607e9ccd4c5b3c8c790ac mes5/SRPMS/glibc-2.8-1.20080520.5.9mnb2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
