DSA-1525-1 asterisk -- several vulnerabilities

Date Reported:

20 Mar 2008

Affected Packages:

asterisk

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2007-6430, CVE-2008-1332, CVE-2008-1333.

More information:

Several remote vulnerabilities have been discovered in Asterisk, a free software PBX and telephony toolkit. The Common Vulnerabilities and Exposures project identifies the following problems:

• CVE-2007-6430

  Tilghman Lesher discovered that database-based registrations are insufficiently validated. This only affects setups, which are configured to run without a password and only host-based authentication.

• CVE-2008-1332

  Jason Parker discovered that insufficient validation of From: headers inside the SIP channel driver may lead to authentication bypass and the potential external initiation of calls.

• CVE-2008-1333

  This update also fixes a format string vulnerability, which can only be triggered through configuration files under control of the local administrator. In later releases of Asterisk this issue is remotely exploitable and tracked as CVE-2008-1333.

The status of the old stable distribution (sarge) is currently being investigated. If affected, an update will be released through security.debian.org.

For the stable distribution (etch), these problems have been fixed in version 1:1.2.13~dfsg-2etch4.

We recommend that you upgrade your asterisk packages.

Fixed in:

Debian GNU/Linux 4.0 (stable)
