+ <title>CHMlib: User-assisted remote execution of arbitrary code</title>
+ <synopsis>
+ A memory corruption vulnerability in CHMlib could lead to the remote
+ execution of arbitrary code.
+ </synopsis>
+ <product type="ebuild">CHMlib</product>
+ <announced>February 27, 2007</announced>
+ <revised>May 20, 2008: 02</revised>
+ <bug>163989</bug>
+ <access>remote</access>
+ <affected>
+ <package name="dev-libs/chmlib" auto="yes" arch="*">
+ <unaffected range="ge">0.39</unaffected>
+ <vulnerable range="lt">0.39</vulnerable>
+ </package>
+ </affected>
+ <background>
+ <p>
+ CHMlib is a library for the MS CHM (Compressed HTML) file format plus
+ extracting and HTTP server utils.
+ </p>
+ </background>
+ <description>
+ <p>
+ When certain CHM files that contain tables and objects stored in pages
+ are parsed by CHMlib, an unsanitized value is passed to the alloca()
+ function resulting in a shift of the stack pointer to arbitrary memory
+ locations.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ An attacker could entice a user to open a specially crafted CHM file,
+ resulting in the execution of arbitrary code with the permissions of
+ the user viewing the file.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All CHMlib users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/chmlib-0.39&quot;</code>
+ </resolution>
