Package        : unarj
Vulnerability  : several
Problem-Type   : local (remote)
Debian-specific: no
CVE ID         : CAN-2004-0947 CAN-2004-1027
Debian Bug     : 281922

Several vulnerabilities have been discovered in unarj, a non-free ARJ
unarchive utility.  The Common Vulnerabilities and Exposures Project
identifies the following vulnerabilities:

CAN-2004-0947

    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.

CAN-2004-1027

    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.


Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
