GLSA-200606-01 : Opera: Buffer overflow

This script is Copyright (C) 2006-2015 Tenable Network Security, Inc.

Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200606-01
(Opera: Buffer overflow)

SEC Consult has discovered a buffer overflow in the code
processing style sheet attributes. It is caused by an integer
signedness error in a length check followed by a call to a string
function. It seems to be hard to exploit this buffer overflow to
execute arbitrary code because of the very large amount memory that has
to be copied.

Impact :

A remote attacker can entice a user to visit a web page containing
a specially crafted style sheet attribute that will crash the user's
browser and maybe lead to the execution of arbitrary code.

Workaround :

There is no known workaround at this time.

Solution :

# emerge --sync
# emerge --ask --oneshot --verbose '>=www-client/opera-8.54'
