-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2013:284 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : glibc Date : November 25, 2013 Affected: Enterprise Server 5.0 _______________________________________________________________________ Problem Description: Multiple vulnerabilities was found and corrected in glibc: Integer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string, which triggers a heap-based buffer overflow (CVE-2012-4412). Stack-based buffer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string that triggers a malloc failure and use of the alloca function (CVE-2012-4424). Multiple integer overflows in malloc/malloc.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allow context-dependent attackers to cause a denial of service (heap corruption) via a large value to the (1) pvalloc, (2) valloc, (3) posix_memalign, (4) memalign, or (5) aligned_alloc functions (CVE-2013-4332). A stack (frame) overflow flaw, which led to a denial of service (application crash), was found in the way glibc's getaddrinfo() function processed certain requests when called with AF_INET6. A similar flaw to CVE-2013-1914, this affects AF_INET6 rather than AF_UNSPEC (CVE-2013-4458). The PTR_MANGLE implementation in the GNU C Library (aka glibc or libc6) 2.4, 2.17, and earlier, and Embedded GLIBC (EGLIBC) does not initialize the random value for the pointer guard, which makes it easier for context- dependent attackers to control execution flow by leveraging a buffer-overflow vulnerability in an application and using the known zero value pointer guard to calculate a pointer address (CVE-2013-4788). The updated packages have been patched to correct these issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-4412 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-4424 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-4332 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-4458 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-4788 _______________________________________________________________________ Updated Packages: Mandriva Enterprise Server 5: ca2e58ecf7a2d62e523b1395175896b5 mes5/i586/glibc-2.8-1.20080520.5.10mnb2.i586.rpm 917ad59055eaebd5e68e5c2e73bb1839 mes5/i586/glibc-devel-2.8-1.20080520.5.10mnb2.i586.rpm 38faa00ce7b79dc37a7494b90c0b4f6c mes5/i586/glibc-doc-2.8-1.20080520.5.10mnb2.i586.rpm 8510201c6ee5f9b9ff4e5a62ea6082d8 mes5/i586/glibc-doc-pdf-2.8-1.20080520.5.10mnb2.i586.rpm a2f9bfe66d75446bd5e963673cb99184 mes5/i586/glibc-i18ndata-2.8-1.20080520.5.10mnb2.i586.rpm b4513eff5fef362f619f6ae0ea35ce5f mes5/i586/glibc-profile-2.8-1.20080520.5.10mnb2.i586.rpm a82b76207b1aca73c057c486a5e07636 mes5/i586/glibc-static-devel-2.8-1.20080520.5.10mnb2.i586.rpm df8b74ecfd447b107364e217da29f5d9 mes5/i586/glibc-utils-2.8-1.20080520.5.10mnb2.i586.rpm 3e9ce8665a7e61176c3b11cd266172b0 mes5/i586/nscd-2.8-1.20080520.5.10mnb2.i586.rpm 8e2ebc125c5a6e7dcf17d4535f7f911c mes5/SRPMS/glibc-2.8-1.20080520.5.10mnb2.src.rpm Mandriva Enterprise Server 5/X86_64: 7c1b3450ba04c65d1a911e44c1554b67 mes5/x86_64/glibc-2.8-1.20080520.5.10mnb2.x86_64.rpm f5fe7d527fc92c69118e8c492e88de4f mes5/x86_64/glibc-devel-2.8-1.20080520.5.10mnb2.x86_64.rpm cc8afd4f3f5d54455d008d24412edc3d mes5/x86_64/glibc-doc-2.8-1.20080520.5.10mnb2.x86_64.rpm 0a946db4c66a3ae2985b983870d9b3fb mes5/x86_64/glibc-doc-pdf-2.8-1.20080520.5.10mnb2.x86_64.rpm 35f418e46f2739e07666b2b80a968c55 mes5/x86_64/glibc-i18ndata-2.8-1.20080520.5.10mnb2.x86_64.rpm c750b3334f6bb43d62370fbf1fc30a74 mes5/x86_64/glibc-profile-2.8-1.20080520.5.10mnb2.x86_64.rpm c6795a180161f94eb06074fdf588a5ed mes5/x86_64/glibc-static-devel-2.8-1.20080520.5.10mnb2.x86_64.rpm 01dd2eaae2dd444ed7b1e80411478a03 mes5/x86_64/glibc-utils-2.8-1.20080520.5.10mnb2.x86_64.rpm 0e29e9d7d90d5a92b19b53cda9642d6c mes5/x86_64/nscd-2.8-1.20080520.5.10mnb2.x86_64.rpm 8e2ebc125c5a6e7dcf17d4535f7f911c mes5/SRPMS/glibc-2.8-1.20080520.5.10mnb2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
