Synopsis :

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

Description :

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.
