Detail
| Multiple stack-based and heap-based buffer overflows in the (1) decode_open_type and (2) udptl_rx_packet functions in main/udptl.c in Asterisk Open Source 1.4.x before 1.4.39.2, 1.6.1.x before 1.6.1.22, 1.6.2.x before 1.6.2.16.2, and 1.8 before 1.8.2.4; Business Edition C.x.x before C.3.6.3; AsteriskNOW 1.5; and s800i (Asterisk Appliance), when T.38 support is enabled, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted UDPTL packet. |

| Id | Description |
|---|---|
| 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. |
