Description


Some vulnerabilities have been reported in LibTIFF, which can be exploited by malicious people to potentially compromise an application using the library.

1) A boundary error within the "EXPAND2D()" macro in libtiff/tif_fax3.h when decoding CCITT Group 4 compressed TIFF images can be exploited to cause a heap-based buffer overflow via specially crafted TIFF images.

Successful exploitation may allow execution of arbitrary code.

2) A boundary error within the ThunderScan decoder when processing images with an incorrect number of bitspersample can be exploited to cause a heap-based buffer overflow via specially crafted ThunderScan encoded files.

3) An error within the handling of certain TIFF files can be exploited to cause a memory corruption by tricking a user into opening a specially crafted TIFF file.

4) An error within the "OJPEGReadHeaderInfoSecStreamSof()" function in libtiff/tif_ojpeg.c can be exploited to cause a memory corruption by tricking a user into opening a specially crafted TIFF file.

5) An integer overflow error exists within the "tiffdump" utility, which can be exploited by e.g. tricking a user into opening a specially crafted TIFF file containing a directory with a large item count.


Solution:
Update to version 3.9.5.
