Ubuntu 8.04 LTS : devhelp, epiphany-browser, midbrowser, yelp update (USN-626-2)

High Nessus Plugin ID 33827

Synopsis

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

Description

USN-626-1 fixed vulnerabilities in xulrunner-1.9. The changes required that Devhelp, Epiphany, Midbrowser and Yelp also be updated to use the new xulrunner-1.9.

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).

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 packages.
