Package : leksbot
Vulnerability : improper setuid-root execution
Problem-Type : local
Debian-specific: yes

Maurice Massar discovered that, due to a packaging error, the program
/usr/bin/KATAXWR was inadvertently installed setuid root. This
program was not designed to run setuid, and contained multiple
vulnerabilities which could be exploited to gain root privileges.

For the stable distribution (woody) this problem has been fixed in
version 1.2-3.1.

The old stable distribution (potato) does not contain a leksbot
package.

For the unstable distribution (sid) this problem has been fixed in
version 1.2-5.

We recommend that you update your leksbot package.
