GLSA-200701-17 : libgtop: Privilege escalation

This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200701-17
(libgtop: Privilege escalation)

Liu Qishuai discovered that glibtop_get_proc_map_s() in
sysdeps/linux/procmap.c does not properly allocate memory for storing a
filename, allowing certain filenames to cause the buffer to overflow on
the stack.

Impact :

By tricking a victim into executing an application that uses the
libgtop library (e.g. libgtop_daemon or gnome-system-monitor), a local
attacker could specify a specially crafted filename to be used by
libgtop causing a buffer overflow and possibly execute arbitrary code
with the rights of the user running the application.

Workaround :

There is no known workaround at this time.

Solution :

All libgtop users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=gnome-base/libgtop-2.14.6'

Risk factor :

Low / CVSS Base Score : 3.7
(CVSS2#AV:L/AC:H/Au:N/C:P/I:P/A:P)
