Description
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
overrunning the buffer, the memory allocation table becomes corrupted,
leading to an eventual crash.
The multi-part body parser in PJSIP contains a logical error that can
make certain multi-part body parts attempt to read memory from outside
the allowed boundaries. A specially crafted packet can trigger these
invalid reads and potentially induce a crash.
This issues is in PJSIP, and so the issue can be fixed without
performing an upgrade of Asterisk at all. However, we are releasing a
new version of Asterisk with the bundled PJProject updated to include
the fix.
If you are running Asterisk with chan_sip, this issue does not affect
you.
