-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDKSA-2006:210 http://www.mandriva.com/security/ _______________________________________________________________________ Package : syslinux Date : November 16, 2006 Affected: 2007.0 _______________________________________________________________________ Problem Description: SYSLINUX is a boot loader for the Linux operating system which operates off an MS-DOS/Windows FAT filesystem. It is built with a private copy of libpng, and as such could be susceptible to some of the same vulnerabilities: Buffer overflow in the png_decompress_chunk function in pngrutil.c in libpng before 1.2.12 allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via unspecified vectors related to "chunk error processing," possibly involving the "chunk_name". (CVE-2006-3334) It is questionable whether this issue is actually exploitable, but the patch to correct the issue has been included in versions < 1.2.12. Tavis Ormandy, of the Gentoo Linux Security Auditing Team, discovered a typo in png_set_sPLT() that may cause an application using libpng to read out of bounds, resulting in a crash. (CVE-2006-5793) Packages have been patched to correct these issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3334 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-5793 _______________________________________________________________________ Updated Packages: Mandriva Linux 2007.0: a2d0440a0b3a9c931479800703a2d60e 2007.0/i586/pxelinux-3.20-3.1mdv2007.0.i586.rpm 1dcefe1c500d17ddc430c9990b202c2b 2007.0/i586/syslinux-3.20-3.1mdv2007.0.i586.rpm 4c973128add1460edb19f4826a1bad7a 2007.0/i586/syslinux-devel-3.20-3.1mdv2007.0.i586.rpm 3893ea9327016ffbd67429924376378d 2007.0/SRPMS/syslinux-3.20-3.1mdv2007.0.src.rpm Mandriva Linux 2007.0/X86_64: f8a364fb18e1a5a17d9112738925555c 2007.0/x86_64/pxelinux-3.20-3.1mdv2007.0.i586.rpm dc169368f3b24012fd34030a82de0367 2007.0/x86_64/syslinux-3.20-3.1mdv2007.0.i586.rpm e4ef6f30ce1ff80b91e21e883eff1d27 2007.0/x86_64/syslinux-devel-3.20-3.1mdv2007.0.i586.rpm 3893ea9327016ffbd67429924376378d 2007.0/SRPMS/syslinux-3.20-3.1mdv2007.0.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
