    Package : asterisk
    Vulnerability : buffer overflow
    Problem type : remote
    Debian-specific: no
    CVE ID : CVE-2013-7100
    Debian Bug : 732355

    Jan Juergens discovered a buffer overflow in the parser for SMS messages
    in Asterisk.

    An additional change was backported, which is fully described in http://downloads.asterisk.org/pub/security/AST-2013-007.html

    With the fix for AST-2013-007, a new configuration option was added in
    order to allow the system adminitrator to disable the expansion of
    "dangerous" functions (such as SHELL()) from any interface which is not
    the dialplan. In stable and oldstable this option is disabled by default.
    To enable it add the following line to the section '[options]' in /etc/asterisk/asterisk.conf (and restart asterisk)

    live_dangerously = no

    For the oldstable distribution (squeeze), this problem has been fixed in version 1:1.6.2.9-2+squeeze12.

    For the stable distribution (wheezy), this problem has been fixed in
    version 1:1.8.13.1~dfsg1-3+deb7u3.

    For the testing distribution (jessie), this problem has been fixed in
    version 1:11.7.0~dfsg-1.

    For the unstable distribution (sid), this problem has been fixed in
    version 1:11.7.0~dfsg-1.

    We recommend that you upgrade your asterisk packages.
