heap buffer overflow running jhead with "poc" option
Running 'jhead poc' with the attached file raises heap buffer overflow
which may allow a remote attacker to cause unspecified impact including
denial-of-service attack
I expected the program to terminate without segfault, but the program crashes
as follow
