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.
