LibTIFF DOTRANGE buffer overflow
|libtiff-dotrange-bo (80339)||High Risk|
LibTIFF is vulnerable to a stack-based buffer overflow, caused by improper bounds checking when handling DOTRANGE tags. 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.
Upgrade to the latest version of LibTIFF (4.0.2 or later), available from the LibTIFF Web site. See References.
