Debian DSA-837-1 : mozilla-firefox - buffer overflow

high Nessus Plugin ID 19806

Synopsis

The remote Debian host is missing a security-related update.

Description

Tom Ferris discovered a bug in the IDN hostname handling of Mozilla Firefox, which is also present in the other browsers from the same family that allows remote attackers to cause a denial of service and possibly execute arbitrary code via a hostname with dashes.

Solution

Upgrade the mozilla-firefox package.

For the stable distribution (sarge) this problem has been fixed in version 1.0.4-2sarge4.
