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 >=3D 3.8.2-r= 4
Description ===========
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 ">=3Dmedia-libs/tiff-3.8.2-r4"
References ==========
