Summary
Gentoo Linux Security Advisory GLSA 200809-07
https://security.gentoo.org/
Severity: Normal
Title: libTIFF: User-assisted execution of arbitrary code
Date: September 08, 2008
Bugs: #234080
ID: 200809-07
Synopsis
=======
Multiple buffer underflow vulnerabilities in libTIFF may allow for the
remote execution of arbitrary code.
Background
=========
libTIFF provides support for reading and manipulating TIFF (Tagged
Image File Format) images.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/tiff < 3.8.2-r4 >= 3.8.2-r4
==========
Drew Yao (Apple Product Security) and Clay Wood reported multiple
buffer underflows in the LZWDecode() and LZWDecodeCompat() functions in
tif_lzw.c when processing TIFF files.
Impact
=====
A remote attacker could entice a user to open a specially crafted TIFF
file with an application making use of libTIFF, possibly resulting in
the remote execution of arbitrary code with the privileges of the user
running the application.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All libTIFF users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/tiff-3.8.2-r4"
