An issue was discovered in Asterisk Open Source 15.x before 15.4.1.
MEDIUM 6.5EPSS 6.70%
Does this matter?
Lower severity and a low EPSS score (6.70%). Track it; it rarely justifies an emergency change on its own.
Description
An issue was discovered in Asterisk Open Source 15.x before 15.4.1. When connected to Asterisk via TCP/TLS, if the client abruptly disconnects, or sends a specially crafted message, then Asterisk gets caught in an infinite loop while trying to read the data stream. This renders the system unusable.
