CVE-2012-0885
chan_sip.c in Asterisk Open Source 1.8.x before 1.8.8.2 and 10.x before 10.0.1, when the res_srtp module is used and media support is improperly configured, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash)…
Does this matter?
Lower severity and a low EPSS score (2.41%). Track it; it rarely justifies an emergency change on its own.
