CVE Reference(s):

Description


Some vulnerabilities have been reported in libTIFF, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system.

1) A boundary error in the "TIFFFetchShortPair()" function in tif_dirread.c can be exploited to cause a stack-based overflow via a TIFF image file with a specially crafted "DotRange", "YCbCrSubsampling", "HalftoneHints", or "PageNumber" tag.

2) Boundary errors within the decoders for JPEG, PixarLog, and NeXT RLE streams can be exploited to cause heap-based buffer overflows.

3) An infinite loop in the "EstimateStripByteCounts()" function can be exploited to cause a DoS.

4) Various unchecked arithmetic operations, including range check operations, can be exploited to bypass certain sanity checks.

5) A flaw within the handling of custom tags can lead to abnormal behaviour.

Successful exploitation allows crashing applications linked against libTIFF or execution of arbitrary code.


Solution:
Update to version 3.9.0beta.
