CVE-2016-2232 [MEDIUM] CVE-2016-2232 asterisk: remote crash vulnerability when receiving UDPTL FAX data (AST-2016-003)
CVE-2016-2232 asterisk: remote crash vulnerability when receiving UDPTL FAX data (AST-2016-003)
The following flaw was found in Asterisk:
If no UDPTL packets are lost there is no problem. However, a lost packet causes Asterisk to use the available error correcting redundancy packets. If those redundancy packets have zero length then Asterisk uses an uninitialized buffer pointer and length value which can cause invalid memory accesses later when the packet is copied.
