LittleCMS, or short lcms, is a color management system for working with
|
|
ICC profiles. It is used by many applications including GIMP and
|
|
Firefox.

|
|
RedHat reported a null-pointer dereference flaw while processing
|
|
monochrome ICC profiles (CVE-2009-0793).
|
|
</p>
|
|
<p>
|
|
Chris Evans of Google discovered the following vulnerabilities:
|
|
</p>
|
|
<ul>
|
|
<li>LittleCMS contains severe memory leaks (CVE-2009-0581).</li>
|
|
<li>LittleCMS is prone to multiple integer overflows, leading to a
|
|
heap-based buffer overflow (CVE-2009-0723).</li>
|
|
<li>The
|
|
ReadSetOfCurves() function is vulnerable to stack-based buffer
|
|
overflows when called from code paths without a bounds check on channel
|
|
counts (CVE-2009-0733).</li>
|
|
</ul>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
A remote attacker could entice a user or automated system to open a
|
|
specially crafted file containing a malicious ICC profile, possibly
|
|
resulting in the execution of arbitrary code with the privileges of the
|
|
user running the application or memory exhaustion, leading to a Denial
|
|
of Service condition.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All LittleCMS users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-libs/lcms-1.18-r1"</code>
|
