Debian Security Advisory DSA 301-1 [email protected] Matt Zimmerman

Package : libgtop
Vulnerability : buffer overflow
Problem-Type : remote
Debian-specific: no
CVE Id : CAN-2001-0928

The gtop daemon, used for monitoring remote machines, contains a
buffer overflow which could be used by an attacker to execute
arbitrary code with the privileges of the daemon process. If started
as root, the daemon process drops root privileges, assuming uid and
gid 99 by default.

This bug was previously fixed in DSA-098, but one of the patches was
not carried over to later versions of libgtop.

For the stable distribution (woody), this problem has been fixed in
version 1.0.13-3.1.

For the old stable distribution (potato), this problem was fixed in

For the unstable distribution (sid), this problem has been fixed in
version 1.0.13-4.

We recommend that you update your libgtop package.
