X.Org: Buffer overflow in XRender extension

1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
x11-base/xorg-x11	< 6.8.2-r7	>= 6.8.2-r7	All supported architectures

Related bugreports: #130979

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

2. Impact Information

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

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

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

3. Resolution Information

There is no known workaround at this time.

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

Code Listing 3.1: Resolution

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