X.Org: Heap overflow in pixmap allocation — GLSA 200509-07

An integer overflow in pixmap memory allocation potentially allows any X.Org user to execute arbitrary code with elevated privileges.

Package	x11-base/xorg-x11 on all architectures
Affected versions	< 6.8.2-r3
Unaffected versions	>= 6.8.2-r3

X.Org is X.Org Foundation's Public Implementation of the X Window System.

X.Org is missing an integer overflow check during pixmap memory allocation.

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

There is no known workaround at this time.

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

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=x11-base/xorg-x11-6.8.2-r3"
