high Nessus Plugin ID 135229

Synopsis

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

Description

Two use-after-free bugs were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could exploit these to cause a denial of service or execute arbitrary code.

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.

Solution

Update the affected firefox package.
