Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
Buffer overflow in the IKEv1 and IKEv2 implementations in Cisco ASA Software before 8.4(7.30), 8.7 before 8.7(1.18), 9.0 before 9.0(4.38), 9.1 before 9.1(7), 9.2 before 9.2(4.5), 9.3 before 9.3(3.7), 9.4 before 9.4(2.4), and 9.5 before 9.5(2.2) on ASA 5500 devices, ASA 5500-X devices, ASA Services Module for Cisco Catalyst 6500 and Cisco 7600 devices, ASA 1000V devices, Adaptive Security Virtual Appliance (aka ASAv), Firepower 9300 ASA Security Module, and ISA 3000 devices allows remote attackers to execute arbitrary code or cause a denial of service (device reload) via crafted UDP packets, aka Bug IDs CSCux29978 and CSCux42019.
