A security issue affects these releases of Ubuntu and its derivatives:

Software Description

Details

A flaw was discovered in the browser engine. A variable could be made to overflow causing the browser to crash. If a user were tricked into opening a malicious web page, an attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2008-2785)

Billy Rios discovered that Firefox did not properly perform URI splitting with pipe symbols when passed a command-line URI. If Firefox were passed a malicious URL, an attacker may be able to execute local content with chrome privileges. (CVE-2008-2933)
