Detailed vulnerability description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can create a use-after-free, triggered by network traffic or a capture file. This was addressed in epan/dissectors/packet-dcerpc-nt.c and epan/dissectors/packet-dcerpc-spoolss.c by using the wmem file scope for private strings, pass it to the affected application and perform a denial of service (DoS) attack.
