- From the www.info-zip.org site:

 Zip 2.3 and (presumably) all previous versions have a buffer-
 overrun vulnerability relating to deep directory paths that could
 potentially lead to local privilege escalation (e.g., in the case of
 automated, Zip-based backups). See the FAQ page for details.

 All versions of UnZip through 5.50 have a number of directory-
 traversal vulnerabilities, and version 5.50 also has a textmode data-
 corruption bug that affects 16-bit ports such as MS-DOS. See the FAQ
 page for details.


Here are the details from the Slackware 10.1 ChangeLog:
+--------------------------+
patches/packages/infozip-5.52-i486-1.tgz: Upgraded to unzip552.tar.gz and
 zip231.tar.gz. These fix some buffer overruns if deep directory paths are
 packed into a Zip archive which could be a security vulnerability (for
 example, in a case of automated archiving or backups that use Zip). However,
 it also appears that these now use certain assembly instructions that might
 not be available on older CPUs, so if you have an older machine you may wish
 to take this into account before deciding whether you should upgrade.
 (* Security fix *)
