Package        : arc
Vulnerability  : insecure temporary file
Problem type   : local
Debian-specific: no
CVE ID         : CAN-2005-2945 CAN-2005-2992

Two vulnerabilities have been discovered in the ARC archive program
under Unix.  The Common Vulnerabilities and Exposures project
identifies the following problems:

CAN-2005-2945

    Eric Romang discovered that the ARC archive program under Unix
    creates a temporary file with insecure permissions which may lead
    to an attacker stealing sensitive information.

CAN-2005-2992

    Joey Schulze discovered that the temporary file was created in an
    insecure fashion as well, leaving it open to a classic symlink
    attack.

The old stable distribution (woody) does not contain arc packages.

For the stable distribution (sarge) these problems have been fixed in
version 5.21l-1sarge1.

For the unstable distribution (sid) these problems have been fixed in
version 5.21m-1.

We recommend that you upgrade your arc 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.
