+ <title>Asterisk: Two SIP Denial of Service vulnerabilities</title>
+ <synopsis>
+ Asterisk is vulnerable to two Denial of Service issues in the SIP channel.
+ </synopsis>
+ <product type="ebuild">asterisk</product>
+ <announced>April 02, 2007</announced>
+ <revised>April 02, 2007: 01</revised>

+ <affected>
+ <package name="net-misc/asterisk" auto="yes" arch="*">
+ <unaffected range="ge">1.2.14-r2</unaffected>

+ <background>
+ <p>
+ Asterisk is an open source implementation of a telephone private branch
+ exchange (PBX).
+ </p>
+ </background>
+ <description>
+ <p>
+ The Madynes research team at INRIA has discovered that Asterisk
+ contains a null pointer dereferencing error in the SIP channel when
+ handling INVITE messages. Furthermore qwerty1979 discovered that
+ Asterisk 1.2.x fails to properly handle SIP responses with return code
+ 0.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ A remote attacker could cause an Asterisk server listening for SIP
+ messages to crash by sending a specially crafted SIP message or
+ answering with a 0 return code.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All Asterisk users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose net-misc/asterisk</code>
+ <p>
+ Note: Asterisk 1.0.x is no longer supported upstream so users should
+ consider upgrading to Asterisk 1.2.x.
