GLSA-200501-07 : xine-lib: Multiple overflows

This script is Copyright (C) 2005-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200501-07
(xine-lib: Multiple overflows)

Ariel Berkman discovered that xine-lib reads specific input data
into an array without checking the input size in demux_aiff.c, making
it vulnerable to a buffer overflow (CAN-2004-1300) . iDefense
discovered that the PNA_TAG handling code in pnm_get_chunk() does not
check if the input size is larger than the buffer size (CAN-2004-1187).
iDefense also discovered that in this same function, a negative value
could be given to an unsigned variable that specifies the read length
of input data (CAN-2004-1188).

Impact :

A remote attacker could craft a malicious movie or convince a
targeted user to connect to a malicious PNM server, which could result
in the execution of arbitrary code with the rights of the user running
any xine-lib frontend.

Workaround :

There is no known workaround at this time.

Solution :

All xine-lib users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose media-libs/xine-lib

Risk factor :

Critical / CVSS Base Score : 10.0
