Vulnerability details
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to memory corruption in the DICOM dissector when checking for a negative length. A remote attacker can inject a malformed packet epan/dissectors/packet-opensafety.c onto the wire or persuade the target user to read a malformed packet trace file and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
