Title: Opera: Multiple vulnerabilities (GLSA 200803-09)
Severity: normal
Exploitable: remote
Date: March 04, 2008
Bug(s): #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: www-client/opera
Vulnerable: < 9.26
Unaffected: >= 9.26
Architectures: 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:
