Ubuntu 12.04 LTS / 14.04 LTS / 14.10 / 15.04 : firefox vulnerability (USN-2571-1)

Medium Nessus Plugin ID 83086


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


Robert Kaiser discovered a use-after-free during plugin initialization in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash or execute arbitrary code with the privileges of the user invoking Firefox.

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.
