CVE-ID: CVE-2018-19210
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition.
The vulnerability exists due to insufficient validation of user-supplied input processed by the TIFFWriteDirectorySec function, as defined in the tif_dirwrite.c source code file. A remote attacker can trick the victim into opening or executing a file that submits malicious input, trigger a NULL pointer dereference and cause the service to crash.
MitigationUpdate the affected package libtiff.
