Package        : tiff
Version        : 4.0.2-6+deb7u20
CVE ID         : CVE-2018-8905
Debian Bug     : 893806 

A heap-based buffer overflow was discovered in the LZWDecodeCompat
function in tif_lzw.c (LibTIFF 4.0.9 and earlier). This vulnerability
might be leveraged by remote attackers to crash the client via a
crafted TIFF LZW file.

For Debian 7 "Wheezy", these problems have been fixed in version
4.0.2-6+deb7u20.

We recommend that you upgrade your tiff packages.
