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

      -------------------------------------------------------------------=

       Package          /  Vulnerable  /                      Unaffected
      -------------------------------------------------------------------=

    1  media-libs/tiff     < 3.8.2-r4                        >=3D 3.8.2-r=
4

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"
