A new vulnerability has been discovered in libXpm, which is included in X.org, that can potentially lead to remote code execution.
|Package||x11-base/xorg-x11 on all architectures|
|Affected versions||< 6.8.2-r1|
|Unaffected versions||revision >= 6.8.0-r5
libXpm is a pixmap manipulation library for the X Window System, included in X.org.
Chris Gilbert has discovered potentially exploitable buffer overflow cases in libXpm that weren't fixed in previous libXpm versions.
A carefully-crafted XPM file could crash X.org, potentially allowing the execution of arbitrary code with the privileges of the user running the application.
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
