+ LHa is a console-based program for packing and unpacking LHarc
+ 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 "&gt;=app-arch/lha-114i-r6"</code>
