Title: libTIFF: User-assisted execution of arbitrary code (GLSA 200809-07)
Date: September 08, 2008
Multiple buffer underflow vulnerabilities in libTIFF may allow for the
remote execution of arbitrary code.
libTIFF provides support for reading and manipulating TIFF (Tagged
Image File Format) images.
Vulnerable: < 3.8.2-r4
Unaffected: >= 3.8.2-r4
Architectures: All supported architectures
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.
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.
There is no known workaround at this time.
All libTIFF users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/tiff-3.8.2-r4"
