Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
Multiple buffer underflow vulnerabilities in libTIFF may allow for the
remote execution of arbitrary code.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
libTIFF provides support for reading and manipulating TIFF (Tagged
Image File Format) images.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
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
=3D=3D=3D=3D=3D=3D
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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All libTIFF users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dmedia-libs/tiff-3.8.2-r4"
