Several vulnerabilities have been discovered in unarj, a non-free ARJ
unarchive utility.  The Common Vulnerabilities and Exposures Project
identifies the following vulnerabilities:
    A buffer overflow has been discovered when handling long file
    names contained in an archive.  An attacker could create a
    specially crafted archive which could cause unarj to crash or
    possibly execute arbitrary code when being extracted by a victim.
    A directory traversal vulnerability has been found so that an
    attacker could create a specially crafted archive which would
    create files in the parent directory when being extracted by a
    victim.  When used recursively, this vulnerability could be used
    to overwrite critical system files and programs.
For the stable distribution (woody) these problems have been fixed in
version 2.43-3woody1.
For the unstable distribution (sid) these problems don\'t apply since
unstable/non-free does not contain the unarj package.
We recommend that you upgrade your unarj package.
