FreeBSD : asterisk -- Buffer Overrun in PJSIP transaction layer (0537afa3-3ce0-11e7-bf9d-001999f8d30b)
The Asterisk project reports : A remote crash can be triggered by sending a SIP packet to Asterisk with a specially crafted CSeq header and a Via header with no branch parameter. The issue is that the PJSIP RFC 2543 transaction key generation algorithm does not allocate a large enough buffer. By...

Digium Asterisk PJSIP Stack ACK Denial of Service
A denial of service vulnerability exists in Digium Asterisk when the PJSIP stack is used. The vulnerability is due to improper processing of ACKs from an unrecognized endpoint, that causes a NULL pointer dereference. A remote unauthenticated attacker can exploit this vulnerability by sending an A...
Asterisk 13.10.x < 13.11.1 ACK Handling Unrecognized Username NULL Pointer Dereference DoS (AST-2016-006)
According to its SIP banner, the version of Asterisk running on the remote host is 13.10.x prior to 13.11.1. It is, therefore, affected by a NULL pointer dereference flaw due to improper handling of ACK packets from an unknown username. An unauthenticated, remote attacker can exploit this to cras...

FreeBSD : asterisk -- Crash on ACK from unknown endpoint (7fda7920-7603-11e6-b362-001999f8d30b)
The Asterisk project reports : Asterisk can be crashed remotely by sending an ACK to it from an endpoint username that Asterisk does not recognize. Most SIP request types result in an 'artificial' endpoint being looked up, but ACKs bypass this lookup. The resulting NULL pointer results in a crash...
Digium Asterisk PJSIP Channel Driver REGISTER Denial of Service
A denial of service vulnerability exists in Digium Asterisk. The vulnerability is due to errors when processing incoming REGISTER requests with lengthy Contact Header URI. A remote authenticated attacker can exploit this vulnerability to cause a denial of service condition...
FreeBSD : PJSIP -- TCP denial of service in PJProject (e21474c6-031a-11e6-aa86-001999f8d30b)
The Asterisk project reports : PJProject has a limit on the number of TCP connections that it can accept. Furthermore, PJProject does not close TCP connections it accepts. By default, this value is approximately 60. An attacker can deplete the number of allowed TCP connections by opening TCP...
FreeBSD : asterisk -- Long Contact URIs in REGISTER requests can crash Asterisk (ee50726e-0319-11e6-aa86-001999f8d30b)
The Asterisk project reports : Asterisk may crash when processing an incoming REGISTER request if that REGISTER contains a Contact header with a lengthy URI. This crash will only happen for requests that pass authentication. Unauthenticated REGISTER requests will not result in a crash occurring...
