CVE-2009-3550
The DCERPC/NT dissector in Wireshark 0.10.10 through 1.0.9 and 1.2.0 through 1.2.2 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a file that records a malformed packet trace.
Does this matter?
Lower severity and a low EPSS score (2.49%). Track it; it rarely justifies an emergency change on its own.
