Vulnerability identifier: #VU16348

CSH Severity: Low

CVE-ID: CVE-2018-19060

CWE-ID: CWE-476

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to cause DoS condicion on the target system.

The vulnerability exists due to NULL pointer dereference condition in the GooString.h source code file when the filenames of embedded files are insufficiently validated before a save path is constructed. A remote attacker can trick the victim into accessing an embedded file that submits malicious input, trigger a NULL pointer dereference and cause the service to crash.
