The vulnerability exists due to insufficient validation of user-supplied input processed by the testcase_read function, as defined in the ext/testcase.c source code file of the affected software. A remote attacker can trick the victim into opening or executing a file that submits malicious input, trigger a NULL pointer dereference condition and cause the affected software to crash, resulting in a DoS condition.
