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.
