A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 8.04 LTS
Software description
- devhelp
- epiphany-browser
- midbrowser
- yelp
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)
