Gentoo Linux Security Advisory
Title: X.Org: Heap overflow in pixmap allocation (GLSA 200509-07)
Severity: high
Exploitable: local
Date: September 12, 2005
Bug(s): #105688
ID: 200509-07
Synopsis
An integer overflow in pixmap memory allocation potentially allows any X.Org user to execute arbitrary code with elevated privileges.
Background
X.Org is X.Org Foundation's Public Implementation of the X Window System.
Affected Packages
Package: x11-base/xorg-x11
Vulnerable: < 6.8.2-r3
Unaffected: >= 6.8.2-r3
Architectures: All supported architectures
Description
X.Org is missing an integer overflow check during pixmap memory allocation.
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: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=x11-base/xorg-x11-6.8.2-r3" |
