Description



The Asterisk project reports:



If an SDP offer or answer is received with the Opus


codec and with the format parameters separated using a


space the code responsible for parsing will recursively


call itself until it crashes. This occurs as the code


does not properly handle spaces separating the parameters.


This does NOT require the endpoint to have Opus configured


in Asterisk. This also does not require the endpoint to


be authenticated. If guest is enabled for chan_sip or


anonymous in chan_pjsip an SDP offer or answer is still


processed and the crash occurs.
