Ubuntu 6.06 LTS / 7.04 / 7.10 : firefox vulnerabilities (USN-623-1)

High Nessus Plugin ID 33544


The remote Ubuntu host is missing one or more security-related patches.


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).

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 packages.
