Several vulnearbilities were discovered in the TIFF manipulation and conversion library:
A buffer overflow allows to execute arbitrary code or cause a denial of service via a crafted TIFF image with JPEG encoding. This issue affects the Debian 5.0 Lenny package only.
A buffer overflow allows to execute arbitrary code or cause a denial of service via a crafted TIFF Internet Fax image file that has been compressed using CCITT Group 4 encoding.
Heap-based buffer overflow in the thunder (aka ThunderScan) decoder allows to execute arbitrary code via a TIFF file that has an unexpected BitsPerSample value.
For the oldstable distribution (lenny), these problems have been fixed in version 3.8.2-11.4.
For the stable distribution (squeeze), these problems have been fixed in version 3.9.4-5+squeeze1.
For the testing distribution, the first two problems have been fixed in version 3.9.4-8, the last problem will be fixed soon.
For the unstable distribution (sid), these problems have been fixed in version 3.9.4-9.
We recommend that you upgrade your tiff packages.
