Mandriva Update for mozilla MDVSA-2012:066 (mozilla)

The remote host is missing an update for the 'mozilla' package(s) announced via the referenced advisory.

Security issues were identified and fixed in mozilla firefox and thunderbird: Mozilla developers identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code (CVE-2012-0468, CVE-2012-0467). Using the Address Sanitizer tool, security researcher Aki Helin from OUSPG found that IDBKeyRange of indexedDB remains in the XPConnect hashtable instead of being unlinked before being destroyed. When it is destroyed, this causes a use-after-free, which is potentially exploitable (CVE-2012-0469). Using the Address Sanitizer tool, security researcher Atte Kettunen from OUSPG found a heap corruption in gfxImageSurface which allows for invalid frees and possible remote code execution. This happens due to float error, resulting from graphics values being passed through different number systems (CVE-2012-0470). Anne van Kesteren of Opera Software found a multi-octet encoding issue where certain octets will destroy the following octets in the processing of some multibyte character sets. This can leave users vulnerable to cross-site scripting (XSS) attacks on maliciously crafted web pages (CVE-2012-0471). Security research firm iDefense reported that researcher wushi of team509 discovered a memory corruption on Windows Vista and Windows 7 systems with hardware acceleration disabled or using incompatible video drivers. This is created by using cairo-dwrite to attempt to render fonts on an unsupported code path. This corruption causes a potentially exploitable crash on affected systems (CVE-2012-0472). Mozilla community member Matias Juntunen discovered an error in WebGLBuffer where FindMaxElementInSubArray receives wrong template arguments from FindMaxUshortElement. This bug causes maximum index to be computed incorrectly within WebGL.drawElements, allowing the reading of illegal video memory (CVE-2012-0473). Security researchers Jordi Chancel and Eddy Bordi reported that they could short-circuit page loads to show the address of a different site than what is loaded in the window in the addressbar. Security researcher Chris McGowen independently reported the same flaw, and further demonstrated that this could lead to loading scripts from the attacker's site, leaving users vulnerable to cross-site scripting (XSS) attacks (CVE-2012-0474 ...
