"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.

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
