Details

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.

Original advisory 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)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 8.04

• midbrowser - 0.3.0rc1a-1~8.04.2
• epiphany-gecko - 2.22.2-0ubuntu0.8.04.5
• devhelp - 0.19-1ubuntu1.8.04.3
• yelp - 2.22.1-0ubuntu2.8.04.2

After a standard system upgrade you need to restart Devhelp, Epiphany,
Midbrowser and Yelp to effect the necessary changes.
