Qt gray-scale buffer overflow
|qt-grayscale-bo (69975)||High Risk|
Qt is vulnerable to a buffer overflow, caused by improper bounds checking by the TIFF reader when parsing malicious files. By persuading a victim to open a specially-crafted gray-scale image file, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
Apply the appropriate update for your system. See References.
