http://security.gentoo.org/

Severity:	normal
Title:	Opera: Two remote code execution vulnerabilities
Date:	01/12/2007
Bugs:	#160369
ID:	200701-08

Synopsis

Two vulnerabilities may allow the execution of arbitrary code.

Background

Opera is a multi-platform web browser.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
www-client/opera	< 9.10	>= 9.10	All supported architectures

Description

Christoph Deal discovered that JPEG files with a specially crafted DHT marker can be exploited to cause a heap overflow. Furthermore, an anonymous person discovered that Opera does not correctly handle objects passed to the "createSVGTransformFromMatrix()" function.

Impact

An attacker could potentially exploit the vulnerabilities to execute arbitrary code with the privileges of the user running Opera by enticing a victim to open a specially crafted JPEG file or a website containing malicious JavaScript code.

Workaround

The vendor recommends disabling JavaScript to avoid the "createSVGTransformFromMatrix" vulnerability. There is no known workaround for the other vulnerability.

Resolution

All Opera users should update to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/opera-9.10"
