arc - insecure temporary file

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.
