<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.

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.

<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.

<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

All X.org users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge sync
|
|
|
|
# emerge -pv ">=x11-base/xorg-x11-6.7.0-r2"
|
|
# emerge ">=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 ">=x11-base/xfree-4.3.0-r7"
|
|
# emerge ">=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.
