+ <title>X.org, XFree86: Integer and stack overflows in libXpm</title>
+ <synopsis>
+ libXpm, the X Pixmap library that is a part of the X Window System,
+ contains multiple stack and integer overflows that may allow a
+ carefully-crafted XPM file to crash applications linked against libXpm,
+ potentially allowing the execution of arbitrary code.

+ <description>
+ <p>
+ 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
+ libXpm.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ A carefully-crafted XPM file could crash applications that are linked
+ against libXpm, potentially allowing the execution of arbitrary code
+ with the privileges of the user running the application.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All X.org users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge sync
+
+ # emerge -pv "&gt;=x11-base/xorg-x11-6.7.0-r2"
+ # emerge "&gt;=x11-base/xorg-x11-6.7.0-r2"</code>
+ <p>
+ All XFree86 users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge sync
+
+ # emerge -pv "&gt;=x11-base/xfree-4.3.0-r7"
+ # emerge "&gt;=x11-base/xfree-4.3.0-r7"</code>
+ <p>
+ 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.
