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