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.
