-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2011:178 http://www.mandriva.com/security/ _______________________________________________________________________ Package : glibc Date : November 25, 2011 Affected: 2010.1, Enterprise Server 5.0 _______________________________________________________________________ Problem Description: Multiple vulnerabilities was discovered and fixed in glibc: Multiple untrusted search path vulnerabilities in elf/dl-object.c in certain modified versions of the GNU C Library (aka glibc or libc6), including glibc-2.5-49.el5_5.6 and glibc-2.12-1.7.el6_0.3 in Red Hat Enterprise Linux, allow local users to gain privileges via a crafted dynamic shared object (DSO) in a subdirectory of the current working directory during execution of a (1) setuid or (2) setgid program that has in (a) RPATH or (b) RUNPATH. NOTE: this issue exists because of an incorrect fix for CVE-2010-3847 (CVE-2011-0536). The GNU C Library (aka glibc or libc6) before 2.12.2 and Embedded GLIBC (EGLIBC) allow context-dependent attackers to execute arbitrary code or cause a denial of service (memory consumption) via a long UTF8 string that is used in an fnmatch call, aka a stack extension attack, a related issue to CVE-2010-2898, as originally reported for use of this library by Google Chrome (CVE-2011-1071). The addmntent function in the GNU C Library (aka glibc or libc6) 2.13 and earlier does not report an error status for failed attempts to write to the /etc/mtab file, which makes it easier for local users to trigger corruption of this file, as demonstrated by writes from a process with a small RLIMIT_FSIZE value, a different vulnerability than CVE-2010-0296 (CVE-2011-1089). locale/programs/locale.c in locale in the GNU C Library (aka glibc or libc6) before 2.13 does not quote its output, which might allow local users to gain privileges via a crafted localization environment variable, in conjunction with a program that executes a script that uses the eval function (CVE-2011-1095). Integer overflow in posix/fnmatch.c in the GNU C Library (aka glibc or libc6) 2.13 and earlier allows context-dependent attackers to cause a denial of service (application crash) via a long UTF8 string that is used in an fnmatch call with a crafted pattern argument, a different vulnerability than CVE-2011-1071 (CVE-2011-1659). crypt_blowfish before 1.1, as used in glibc on certain platforms, does not properly handle 8-bit characters, which makes it easier for context-dependent attackers to determine a cleartext password by leveraging knowledge of a password hash (CVE-2011-2483). The updated packages have been patched to correct these issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-0536 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-1071 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-1089 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-1095 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-1659 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-2483 _______________________________________________________________________ Updated Packages: Mandriva Linux 2010.1: 4af7f6efb12c5be3ad435a6d9865be57 2010.1/i586/glibc-2.11.1-8.3mnb2.i586.rpm 82f97e43fc7ab7ee2fbfc92d9ed844f0 2010.1/i586/glibc-devel-2.11.1-8.3mnb2.i586.rpm 013f4da3b270a6860e9ae171b456a488 2010.1/i586/glibc-doc-2.11.1-8.3mnb2.i586.rpm 65da2025a253885a3a3e0699eb407a61 2010.1/i586/glibc-doc-pdf-2.11.1-8.3mnb2.i586.rpm e5b6f256bad2b8afa7674e2f4d3c80bc 2010.1/i586/glibc-i18ndata-2.11.1-8.3mnb2.i586.rpm 319ecf5d08bc0e0aab9b0cf3e5cf6a6e 2010.1/i586/glibc-profile-2.11.1-8.3mnb2.i586.rpm 99c144bfc7581d9f3b885c7a630c89ce 2010.1/i586/glibc-static-devel-2.11.1-8.3mnb2.i586.rpm 966e023400d62e841942b69bae4d06de 2010.1/i586/glibc-utils-2.11.1-8.3mnb2.i586.rpm 577f1f88b14add8ea8753b17d730cb8a 2010.1/i586/nscd-2.11.1-8.3mnb2.i586.rpm 2e1bffb07071cb21ef6363c21588f4b7 2010.1/SRPMS/glibc-2.11.1-8.3mnb2.src.rpm Mandriva Linux 2010.1/X86_64: 05e4da86aea47726b27c00e3f26e3445 2010.1/x86_64/glibc-2.11.1-8.3mnb2.x86_64.rpm d3689fe0a7ae8e4c0e309b34c82cabfd 2010.1/x86_64/glibc-devel-2.11.1-8.3mnb2.x86_64.rpm b8be4de2a9c6a8e3effe06234429a227 2010.1/x86_64/glibc-doc-2.11.1-8.3mnb2.x86_64.rpm 1ac19950a67c4ee965b0ae9d2d6a0396 2010.1/x86_64/glibc-doc-pdf-2.11.1-8.3mnb2.x86_64.rpm 54031c917cb54a5abc42ebaf30dfe894 2010.1/x86_64/glibc-i18ndata-2.11.1-8.3mnb2.x86_64.rpm 18c2a1354df2094a7508b1990420ab5b 2010.1/x86_64/glibc-profile-2.11.1-8.3mnb2.x86_64.rpm f8cef0d317c3ccbb5446672a1cf00ad6 2010.1/x86_64/glibc-static-devel-2.11.1-8.3mnb2.x86_64.rpm 78b27e0739627abebc7c43fbf82e107b 2010.1/x86_64/glibc-utils-2.11.1-8.3mnb2.x86_64.rpm e37194682e8ef10c21a8d8483e76b3f4 2010.1/x86_64/nscd-2.11.1-8.3mnb2.x86_64.rpm 2e1bffb07071cb21ef6363c21588f4b7 2010.1/SRPMS/glibc-2.11.1-8.3mnb2.src.rpm Mandriva Enterprise Server 5: 73cffaaa03648c9eb01ed50b5fdd0cee mes5/i586/glibc-2.8-1.20080520.5.8mnb2.i586.rpm 5e9ec7d6e3f319b5076dd51506d47032 mes5/i586/glibc-devel-2.8-1.20080520.5.8mnb2.i586.rpm c80b37f1a750968735f8ce51c920e84e mes5/i586/glibc-doc-2.8-1.20080520.5.8mnb2.i586.rpm 7de1f541c2bf6e17a4f3007cad517140 mes5/i586/glibc-doc-pdf-2.8-1.20080520.5.8mnb2.i586.rpm 27a365665846989b629b0cb3fb15acfd mes5/i586/glibc-i18ndata-2.8-1.20080520.5.8mnb2.i586.rpm 3f2f68a0bc47bace3586919671c7f1b4 mes5/i586/glibc-profile-2.8-1.20080520.5.8mnb2.i586.rpm 17019cf79cf3864c537e12aefd48a23d mes5/i586/glibc-static-devel-2.8-1.20080520.5.8mnb2.i586.rpm 7ad8f634ee4e0c5fc0f340dcfebcf0fb mes5/i586/glibc-utils-2.8-1.20080520.5.8mnb2.i586.rpm 53a5dc175995723322a13a7e3bbd6c41 mes5/i586/nscd-2.8-1.20080520.5.8mnb2.i586.rpm 6fcd77d9eac9fa71f91dcb1218afd628 mes5/SRPMS/glibc-2.8-1.20080520.5.8mnb2.src.rpm Mandriva Enterprise Server 5/X86_64: 33f73ece95aa39c59e0370449f13d3af mes5/x86_64/glibc-2.8-1.20080520.5.8mnb2.x86_64.rpm 626f8e4774270e50c5e9bf2bc7dfa64c mes5/x86_64/glibc-devel-2.8-1.20080520.5.8mnb2.x86_64.rpm c9d59258ac0fc0463c585405bb46327a mes5/x86_64/glibc-doc-2.8-1.20080520.5.8mnb2.x86_64.rpm f81b494a1d394c48921c99983288c538 mes5/x86_64/glibc-doc-pdf-2.8-1.20080520.5.8mnb2.x86_64.rpm 1c972a49ecbfc91d0a156dd743894c14 mes5/x86_64/glibc-i18ndata-2.8-1.20080520.5.8mnb2.x86_64.rpm 45aa431a8a9920d188698ae64fe5466d mes5/x86_64/glibc-profile-2.8-1.20080520.5.8mnb2.x86_64.rpm ecf5dca4c8bc49c1e3ebeb2a698b38a3 mes5/x86_64/glibc-static-devel-2.8-1.20080520.5.8mnb2.x86_64.rpm 8de7d2dfa8ea598aac75faf24f606f13 mes5/x86_64/glibc-utils-2.8-1.20080520.5.8mnb2.x86_64.rpm 7615c6e96903c8c146d5ae2d2912c6ee mes5/x86_64/nscd-2.8-1.20080520.5.8mnb2.x86_64.rpm 6fcd77d9eac9fa71f91dcb1218afd628 mes5/SRPMS/glibc-2.8-1.20080520.5.8mnb2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
