archives.

<description>
<p>
Tavis Ormandy of the Google Security Team discovered several
vulnerabilities in the LZH decompression component used by LHa. The
make_table function of unlzh.c contains an array index error and a
buffer overflow vulnerability. The build_tree function of unpack.c
contains a buffer underflow vulnerability. Additionally, unlzh.c
contains a code that could run in an infinite loop.
</p>
</description>
<impact type="normal">
<p>
By enticing a user to uncompress a specially crafted archive, a remote
attacker could cause a Denial of Service by CPU consumption or execute
arbitrary code with the rights of the user running the application.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All LHa users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-arch/lha-114i-r6&quot;</code>
</resolution>
