X.Org: Buffer overflow in XRender extension — GLSA 200605-02

A buffer overflow in the XRender extension potentially allows any X.Org user to execute arbitrary code with elevated privileges.

Affected Packages

x11-base/xorg-x11 on all architectures
Affected versions < 6.8.2-r7
Unaffected versions >= 6.8.2-r7

Background

X.Org is X.Org Foundation's public implementation of the X Window System.

Description

X.Org miscalculates the size of a buffer in the XRender extension.

Impact

An X.Org user could exploit this issue to make the X server execute arbitrary code with elevated privileges.

Workaround

There is no known workaround at this time.

Resolution

All X.Org users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=x11-base/xorg-x11-6.8.2-r7"
