Multiple buffer overflows in Asterisk Open Source 1.4.x before 1.4.18.1 and
1.4.19-rc3, Open Source 1.6.x before 1.6.0-beta6, Business Edition C.x.x
before C.1.6.1, AsteriskNOW 1.0.x before 1.0.2, Appliance Developer Kit
before 1.4 revision 109386, and s800i 1.1.x before 1.1.0.2 allow remote
attackers to (1) write a zero to an arbitrary memory location via a large
RTP payload number, related to the ast_rtp_unset_m_type function in
main/rtp.c; or (2) write certain integers to an arbitrary memory location
via a large number of RTP payloads, related to the process_sdp function in
channels/chan_sip.c.
