Synopsis
========
Opera contains an integer signedness error resulting in a buffer
overflow which may allow a remote attacker to execute arbitrary code.
Background
==========
Opera is a multi-platform web browser.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-client/opera lt; 8.54 gt;= 8.54
Description
===========
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.
Resolution
==========
All Opera users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose "gt;=www-client/opera-8.54"
References
==========
[ 1 ] CVE-2006-1834
