DESCRIPTION:
A security issue has been reported in Kerberos Applications, which
can be exploited by malicious users to bypass certain security
restrictions.
The security issue is caused due to the FTP daemon failing to drop
its effective group identifier (EGID) privileges. This can be
exploited to gain access to files and directories owned by the same
group as the EGID of the daemon process.
The security issue is reported in version 1.0.1 and prior.
SOLUTION:
Apply patch (please see the vendor's advisory for details).
PROVIDED AND/OR DISCOVERED BY:
