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
recorded in asterisk's menuselect system, knocking out ODBC build if not
present (though this is only done, afaict, due to a missing dependency
in a unixodbc package on some linux version), so add libltdl as a
BUILD_DEPENDS.
Doesn't affect the packages, other than -odbc wasn't built before
unless you had libltdl installed, so no bump.
- Fix compliance with RFC 3261 section 18.2.2. (aka Cisco phone fix)
- Resolve a change in IPv6 header parsing due to the Cisco phone fix issue.
- Resolve potential crash when using SIP TLS support.
- Improve reliability when using SIP TLS.
- AST-2011-006, shell access via remote authenticated manager
sessions (logged-in manager users can execute shell commands via
the manager interface without having the "system" privilege that
should be required)
- AST-2011-005, DoS with remote unauthenticated sessions (add limits
to prevent unauthenticated users from tying up all available FDs for
the manager interface, SIP-over-TCP, Skinny and the built in HTTP
server).
(updating by way of upstream patch file, the full tar.gz isn't
available yet).
