Ubuntu 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : firefox vulnerabilities (USN-1608-1)

Critical Nessus Plugin ID 62515


The remote Ubuntu host is missing a security-related patch.


It was discovered that the browser engine used in Firefox contained a memory corruption flaw. If a user were tricked into opening a specially crafted web page, a remote attacker could cause Firefox to crash or potentially execute arbitrary code as the user invoking the program. (CVE-2012-4191)

It was discovered that Firefox allowed improper access to the Location object. An attacker could exploit this to obtain sensitive information. (CVE-2012-4192).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected firefox package.
