GLSA-200410-08 : ncompress: Buffer overflow

This script is Copyright (C) 2004-2014 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-200410-08
(ncompress: Buffer overflow)

compress and uncompress do not properly check bounds on command line
options, including the filename. Large parameters would trigger a
buffer overflow.

Impact :

By supplying a carefully crafted filename or other option, an attacker
could execute arbitrary code on the system. A local attacker could only
execute code with his own rights, but since compress and uncompress are
called by various daemon programs, this might also allow a remote
attacker to execute code with the rights of the daemon making use of
ncompress.

Workaround :

There is no known workaround at this time.

Solution :

All ncompress users should upgrade to the latest version:
# emerge sync
# emerge -pv '>=app-arch/ncompress-4.2.4-r1'
# emerge '>=app-arch/ncompress-4.2.4-r1'

Risk factor :

High / CVSS Base Score : 7.5
