http://downloads.asterisk.org/pub/telephony/asterisk/ChangeLog-1.6.2.1 9 The Asterisk Development Team has announced the release of Asterisk versions 1.4.41.1, 1.6.2.18.1, and 1.8.4.3, which are security releases.
These releases are available for immediate download at http://downloads.asterisk.org/pub/telephony/asterisk/releases
The release of Asterisk 1.4.41.1, 1.6.2.18, and 1.8.4.3 resolves several issues as outlined below :
- AST-2011-008: If a remote user sends a SIP packet containing a null, Asterisk assumes available data extends past the null to the end of the packet when the buffer is actually truncated when copied. This causes SIP header parsing to modify data past the end of the buffer altering unrelated memory structures. This vulnerability does not affect TCP/TLS connections. -- Resolved in 1.6.2.18.1 and 1.8.4.3
- AST-2011-009: A remote user sending a SIP packet containing a Contact header with a missing left angle bracket (<) causes Asterisk to access a NULL pointer. -- Resolved in 1.8.4.3
- AST-2011-010: A memory address was inadvertently transmitted over the network via IAX2 via an option control frame and the remote party would try to access it. -- Resolved in 1.4.41.1, 1.6.2.18.1, and 1.8.4.3
The issues and resolutions are described in the AST-2011-008, AST-2011-009, and AST-2011-010 security advisories.
For more information about the details of these vulnerabilities, please read the security advisories AST-2011-008, AST-2011-009, and AST-2011-010, which were released at the same time as this announcement.
