CVE-2012-5237
The dissect_hsrp function in epan/dissectors/packet-hsrp.c in the HSRP dissector in Wireshark 1.8.x before 1.8.3 allows remote attackers to cause a denial of service (infinite loop) via a malformed packet.
Does this matter?
Lower severity and a low EPSS score (0.89%). Track it; it rarely justifies an emergency change on its own.
