Gentoo Linux Security Advisory GLSA 200803-09


                                        http://security.gentoo.org/

Severity: Normal
Title: Opera: Multiple vulnerabilities
Date: March 04, 2008
Bugs: #210260
ID: 200803-09


Synopsis

Multiple vulnerabilities have been discovered in Opera, allowing for
file disclosure, privilege escalation and Cross-Site scripting.

Background

Opera is a fast web browser that is available free of charge.

Affected packages

-------------------------------------------------------------------
 Package           /  Vulnerable  /                     Unaffected
-------------------------------------------------------------------

1 www-client/opera < 9.26 >= 9.26

Description

Mozilla discovered that Opera does not handle input to file form fields
properly, allowing scripts to manipulate the file path (CVE-2008-1080).
Max Leonov found out that image comments might be treated as scripts,
and run within the wrong security context (CVE-2008-1081). Arnaud
reported that a wrong representation of DOM attribute values of
imported XML documents allows them to bypass sanitization filters
(CVE-2008-1082).

Impact

A remote attacker could entice a user to upload a file with a known
path by entering text into a specially crafted form, to execute scripts
outside intended security boundaries and conduct Cross-Site Scripting
attacks.

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 &quot;&gt;=www-client/opera-9.26&quot;
