70968 | Asterisk main/udptl.c Multiple Function UPDTL Packet Handling Overflow Asterisk is prone to an overflow condition. The 'decode_open_type()' and 'udptl_rx_packet()' functions in 'main/udptl.c' fail to properly sanitize user-supplied input resulting in a stack-based buffer overflow. With a specially crafted UDPTL packet, a remote attacker can potentially execute arbitrary code. |
