Synopsis :

The remote Fedora host is missing a security update.

Description :

Remove systemd dependencies from EL6 and F15 The Asterisk Development
Team has announced the release of Asterisk versions 1.4.41.2,
1.6.2.18.2, and 1.8.4.4, which are security releases.

These releases are available for immediate download at
http://downloads.asterisk.org/pub/telephony/asterisk/releases

The release of Asterisk 1.4.41.2, 1.6.2.18.2, and 1.8.4.4 resolves the
following issue :

AST-2011-011: Asterisk may respond differently to SIP requests from an
invalid SIP user than it does to a user configured on the system, even
when the alwaysauthreject option is set in the configuration. This can
leak information about what SIP users are valid on the Asterisk
system.

For more information about the details of this vulnerability, please
read the security advisory AST-2011-011, which was released at the
same time as this announcement.

http://downloads.asterisk.org/pub/security/AST-2011-011.pdf 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
