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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
