USN-626-1: Firefox and xulrunner vulnerabilities

Packages

firefox-3.0 -
xulrunner-1.9 -

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 and xulrunner, as used by browsers
such as Epiphany, did not properly perform URI splitting with pipe
symbols when passed a command-line URI. If Firefox or xulrunner were
passed a malicious URL, an attacker may be able to execute local
content with chrome privileges. (CVE-2008-2933)
