=========================================================== Ubuntu Security Notice USN-407-1 January 15, 2007 libgtop2 vulnerability https://launchpad.net/bugs/79206 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 5.10 Ubuntu 6.06 LTS Ubuntu 6.10 This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. The problem can be corrected by upgrading your system to the following package versions: Ubuntu 5.10: libgtop2-5 2.12.0-0ubuntu1.1 Ubuntu 6.06 LTS: libgtop2-7 2.14.1-0ubuntu1.1 Ubuntu 6.10: libgtop2-7 2.14.4-0ubuntu1.1 In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: Liu Qishuai discovered a buffer overflow in the /proc parsing routines in libgtop. By creating and running a process in a specially crafted long path and tricking an user into running gnome-system-monitor, an attacker could exploit this to execute arbitrary code with the user's privileges.
