+ <description>
+ <p>
+ Tavis Ormandy of the Google Security Team discovered a static buffer
+ underflow in ncompress.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ An attacker could create a specially crafted LZW archive, that when
+ decompressed by a user or automated system would result in the
+ execution of arbitrary code with the permissions of the user invoking
+ the utility.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All ncompress users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose &quot;&gt;=app-arch/ncompress-4.2.4.1&quot;</code>
