Vulnerability Assessment Details
X.org, XFree86: Integer and stack overflows in libXpm
Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200409-34
(X.org, XFree86: Integer and stack overflows in libXpm)
Chris Evans has discovered multiple integer and stack overflow
vulnerabilities in the X Pixmap library, libXpm, which is a part of the X
Window System. These overflows can be exploited by the execution of a
malicious XPM file, which can crash applications that are dependent on
A carefully-crafted XPM file could crash applications that are linked
against libXpm, potentially permiting the execution of arbitrary code with
the rights 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 -pv ">=x11-base/xorg-x11-6.7.0-r2"
# emerge ">=x11-base/xorg-x11-6.7.0-r2"
All XFree86 users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=x11-base/xfree-4.3.0-r7"
# emerge ">=x11-base/xfree-4.3.0-r7"
Note: Usage of XFree86 is deprecated on the AMD64, HPPA, IA64, MIPS, PPC
and SPARC architectures: XFree86 users on those architectures should switch
to X.org rather than upgrading XFree86.
