Gentoo Linux Security Advisory

Title: Opera: Command-line URL shell command injection (GLSA 200512-10)
Severity: normal
Exploitable: remote
Date: December 18, 2005
Bug(s): #113239
ID: 200512-10

Synopsis

Lack of URL validation in Opera command-line wrapper could be abused to execute arbitrary commands.

Background

Opera is a multi-platform web browser.

Affected Packages

Package: www-client/opera
Vulnerable: < 8.51
Unaffected: >= 8.51
Architectures: All supported architectures


Description

Peter Zelezny discovered that the shell script used to launch Opera parses shell commands that are enclosed within backticks in the URL provided via the command line.

Impact

A remote attacker could exploit this vulnerability by enticing a user to follow a specially crafted URL from a tool that uses Opera to open URLs, resulting in the execution of arbitrary commands on the targeted machine.

Workaround

There is no known workaround at this time.

Resolution

All Opera users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/opera-8.51"
