Message-Id: <E1UPuOa-0003TQ-GI@titan.mandriva.com> Date: Wed, 10 Apr 2013 14:45:00 +0200 From: security@...driva.com To: full-disclosure@...ts.grok.org.uk Subject: [ MDVSA-2013:113 ] perl -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2013:113 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : perl Date : April 10, 2013 Affected: Business Server 1.0 _______________________________________________________________________ Problem Description: Updated perl packages fix security vulnerability: It was discovered that Perl's 'x' string repeat operator is vulnerable to a heap-based buffer overflow. An attacker could use this to execute arbitrary code (CVE-2012-5195). The _compile function in Maketext.pm in the Locale::Maketext implementation in Perl before 5.17.7 does not properly handle backslashes and fully qualified method names during compilation of bracket notation, which allows context-dependent attackers to execute arbitrary commands via crafted input to an application that accepts translation strings from users (CVE-2012-6329). In order to prevent an algorithmic complexity attack against its hashing mechanism, perl will sometimes recalculate keys and redistribute the contents of a hash. This mechanism has made perl robust against attacks that have been demonstrated against other systems. Research by Yves Orton has recently uncovered a flaw in the rehashing code which can result in pathological behavior. This flaw could be exploited to carry out a denial of service attack against code that uses arbitrary user input as hash keys. Because using user-provided strings as hash keys is a very common operation, we urge users of perl to update their perl executable as soon as possible. Updates to address this issue have bene pushed to main-5.8, maint-5.10, maint-5.12, maint-5.14, and maint-5.16 branches today. Vendors* were informed of this problem two weeks ago and are expected to be shipping updates today (or otherwise very soon) (CVE-2013-1667). _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-5195 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-6329 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-1667 https://wiki.mageia.org/en/Support/Advisories/MGASA-2012-0352 https://wiki.mageia.org/en/Support/Advisories/MGASA-2013-0032 https://wiki.mageia.org/en/Support/Advisories/MGASA-2013-0094 _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: e010dd5d07ad358f78a421e97d158cc5 mbs1/x86_64/perl-5.14.2-8.1.mbs1.x86_64.rpm 2b935278aa38f3ed01fb4859036fc17a mbs1/x86_64/perl-base-5.14.2-8.1.mbs1.x86_64.rpm 8b2791b988a751ad818bbae21854bfe4 mbs1/x86_64/perl-devel-5.14.2-8.1.mbs1.x86_64.rpm 54a4521ed44b8728a1fa8af387d1e9c2 mbs1/x86_64/perl-doc-5.14.2-8.1.mbs1.noarch.rpm c7d0a40057c4ec1d24baa9b605dea7cd mbs1/x86_64/perl-Locale-Maketext-1.220.0-2.1.mbs1.noarch.rpm 1e7634153853dabcec48738081b1c2ec mbs1/SRPMS/perl-5.14.2-8.1.mbs1.src.rpm e1790a3f5f3c579ce1e5e0cb43cb6b08 mbs1/SRPMS/perl-Locale-Maketext-1.220.0-2.1.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
