SOT Linux Security Advisory

Subject: Updated mc package for SOT Linux 2003
Advisory ID: SLSA-2004:16
Date: Monday, April 12, 2004

1. Problem description

According to a message from Ilya Teterin posted on Bugtraq, the Midnight Commander application uses a uninitialized buffer to handle symlinks in VFS. This allows attackers to execute arbitrary code during symlink conversion. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2003-1023 to the problem.

Users of MC should update to these erratum packages which are not vulnerable to this issue.
