GLSA-200408-14 : acroread: UUDecode filename 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-200408-14
(acroread: UUDecode filename buffer overflow)

acroread contains two errors in the handling of UUEncoded filenames.
First, it fails to check the length of a filename before copying it
into a fixed size buffer and, secondly, it fails to check for the
backtick shell metacharacter in the filename before executing a command
with a shell.

Impact :

By enticing a user to open a PDF with a specially crafted filename, an
attacker could execute arbitrary code or programs with the permissions
of the user running acroread.

Workaround :

There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version of acroread.
