Ubuntu Security Notice USN-1355-2

Posted Feb 4, 2012

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1355-2 - USN-1355-1 fixed vulnerabilities in Firefox. This update provides an updated Mozvoikko package for use with the latest Firefox. It was discovered that if a user chose to export their Firefox Sync key the "Firefox Recovery Key.html" file is saved with incorrect permissions, making the file contents potentially readable by other users. Nicolas Gregoire and Aki Helin discovered that when processing a malformed embedded XSLT stylesheet, Firefox can crash due to memory corruption. If the user were tricked into opening a specially crafted page, an attacker could exploit this to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. Various other issues were also addressed.
