http://security.gentoo.org/

Severity:	normal
Title:	Opera: Multiple vulnerabilities
Date:	03/04/2008
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	Architecture(s)
www-client/opera	< 9.26	>= 9.26	All supported architectures

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 ">=www-client/opera-9.26"
