Synopsis ========
A vulnerability in X.Org X11 library could lead to a Denial of Service condition.
Background ==========
X.Org is an implementation of the X Window System. The X.Org X11 library provides the X11 protocol library files.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-libs/libX11 < 1.7.1 >= 1.7.1
Description ===========
It was discovered that XLookupColor() and other X.Org X11 library functions lacked proper validation of the length of their string parameters.
Impact ======
An attacker could emit arbitrary X protocol requests to the X server through malicious crafted string parameters in applications linked against X.Org X11 library.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All X.Org X11 library users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=x11-libs/libX11-1.7.1"
