Asterisk Project Security Advisory - AST-2017-009

Buffer overflow in pjproject header parsing can cause crash in Asterisk

By carefully crafting invalid values in the Cseq and the Via header port, pjproject’s packet parsing code can create strings larger than the buffer allocated to hold them. This will usually cause Asterisk to crash immediately. The packets do not have to be authenticated.


Asterisk Project Security Advisory - AST-2017-010 - CVE-2017-16671

Buffer overflow in CDR's set user

No size checking is done when setting the user field for Party B on a CDR. Thus, it is possible for someone to use an arbitrarily large string and write past the end of the user field storage buffer. The earlier AST-2017-001 advisory for the CDR user field overflow was for the Party A buffer.


Asterisk Project Security Advisory - AST-2017-011 - CVE-2017-16672

Memory/File Descriptor/RTP leak in pjsip session resource

A memory leak occurs when an Asterisk pjsip session object is created and that call gets rejected before the session itself is fully established. When this happens the session object never gets destroyed. This then leads to file descriptors and RTP ports being leaked as well.
