CVE-2019-15297
res_pjsip_t38 in Sangoma Asterisk 15.x before 15.7.4 and 16.x before 16.5.1 allows an attacker to trigger a crash by sending a declined stream in a response to a T.38 re-invite initiated by Asterisk.
Does this matter?
Lower severity and a low EPSS score (3.39%). Track it; it rarely justifies an emergency change on its own.
