Description:
Multiple 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) Boundary errors within the RLE decoding in "tif_next.c", "tif_thunder.c", and "tif_luv.c" can be exploited to cause heap-based buffer overflows. This can be exploited with a specially crafted TIFF image file to execute arbitrary code via an application linked to the vulnerable library.
2) Some unspecified integer overflows may potentially allow arbitrary code execution on a user's system.
3) A division-by-zero error can be exploited via an integer overflow to crash an application linked against the vulnerable library.
4) A division-by-zero error in the handling of "YCbCr subsampling" values in TIFF image headers can be exploited to crash an application linked against the vulnerable library.
The vulnerabilities have been reported in version 3.6.1. Other versions may also be affected.
Solution:
Update to version 3.7.1 or later.
