SynopsisThe remote Debian host is missing a security update.
Descriptiontiff3 is affected by multiple issues that can result at least in denial of services of applications using libtiff4. Crafted TIFF files can be provided to trigger: abort() calls via failing assertions, buffer overruns (both in read and write mode).
tif_luv.c in libtiff allows attackers to cause a denial of service (out-of-bounds write) via an invalid number of samples per pixel in a LogL compressed TIFF image.
tif_luv.c in libtiff allows attackers to cause a denial of service (out-of-bounds writes) via a crafted TIFF image.
tif_luv.c in libtiff allows attackers to cause a denial of service (out-of-bounds reads) via a crafted TIFF image.
The NeXTDecode function in tif_next.c in LibTIFF allows remote attackers to cause a denial of service (out-of-bounds write) via a crafted TIFF image.
tif_pixarlog.c in libtiff 4.0.6 has out-of-bounds write vulnerabilities in heap allocated buffers.
tif_write.c in libtiff 4.0.6 has an issue in the error code path of TIFFFlushData1() that didn't reset the tif_rawcc and tif_rawcp members.
tif_predict.h and tif_predict.c in libtiff 4.0.6 have assertions that can lead to assertion failures in debug mode, or buffer overflows in release mode, when dealing with unusual tile size like YCbCr with subsampling.
For Debian 7 'Wheezy', these problems have been fixed in version 3.9.6-11+deb7u4.
We recommend that you upgrade your tiff3 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.
