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)
