Description

Update to 1.6.1.17 * AST-2010-003: Invalid parsing of ACL rules can compromise security * AST-2010-002: This security release is intended to raise awareness of how it is possible to insert malicious strings into dialplans, and to advise developers to read the best practices documents so that they may easily avoid these dangers. * AST-2010-001: An attacker attempting to negotiate T.38 over SIP can remotely crash Asterisk by modifying the FaxMaxDatagram field of the SDP to contain either a negative or exceptionally large value. The same crash occurs when the FaxMaxDatagram field is omitted from the SDP as well.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
