LibTIFF t2p_read_tiff_init() buffer overflow
|libtiff-t2preadtiffinit-bo (77088)||High Risk|
LibTIFF is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the t2p_read_tiff_init() function. By persuading a victim to open a specially-crafted TIFF file, a remote attacker could exploit this vulnerability to overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the affected application to crash.
Apply the appropriate update for your system. See References.

- CVE-2012-3401: The t2p_read_tiff_init function in tiff2pdf (tools/tiff2pdf.c) in LibTIFF 4.0.2 and earlier does not properly initialize the T2P context struct pointer in certain error conditions, which allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted TIFF image that triggers a heap-based buffer overflow.
