GLSA-200809-07 : libTIFF: User-assisted execution of arbitrary code

Medium Nessus Plugin ID 34114


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200809-07 (libTIFF: User-assisted execution of arbitrary code)

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.


All libTIFF users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/tiff-3.8.2-r4'
