Mandrake Linux Security Update Advisory
________________________________________________________________________
Package name: libgtop
Date: December 19th, 2001
Advisory ID: MDKSA-2001:094
Affected versions: 7.1, 7.2, 8.0, 8.1, Corporate Server 1.0.1
________________________________________________________________________
Problem Description:
A remote format string vulnerability was found in the libgtop daemon by
Laboratory intexxia. By sending a specially crafted format string to
the server, a remote attacker could potentially execute arbitrary code
on the remote system with the daemon's permissions. By default libgtop
runs as the user nobody, but the flaw could be used to compromise local
system security by allowing the attacker to exploit other local
vulnerabilities. A buffer overflow was also found by Flavio Veloso
which could allow the client to execute code on the server. Both
vulnerabilities are patched in this update and will be fixed upstream
in version 1.0.14. libgtop_daemon is not invoked by default anywhere
in Mandrake Linux.

Mandrake Linux 8.1, look for it in "updates/8.1/RPMS/". Updated source
RPMs are available as well, but you generally do not need to download
them.
Please be aware that sometimes it takes the mirrors a few hours to
update.
