Name of the Vulnerable Software and Affected Versions ImageMagick versions prior to 6.9.13-44 ImageMagick versions prior to 7.1.2-19

Description The viff encoder contains an integer truncation or wraparound issue on 32-bit builds. This can trigger an out of bounds heap write, potentially causing a crash.
