Multiple Vulnerabilities in Asterisk 1.2.10 [MU-200608-01] August 23, 2006 http://labs.musecurity.com/advisories.html Affected Product/Versions: Asterisk 1.0.0 through 1.2.10 Product Overview: http://www.asterisk.org/features "Asterisk-based telephony solutions offer a rich and flexible feature set. Asterisk offers both classical PBX functionality and advanced features, and interoperates with traditional standards-based telephony systems and Voice over IP systems. Asterisk offers the features one would expect of a large proprietary PBX system such as Voicemail, Conference Bridging, Call Queuing, and Call Detail Records." Vulnerability Details: A remote stack buffer overflow condition in Asterisk's MGCP implementation could allow for arbitrary code execution. The vulnerable code is triggered with the use of a malformed AUEP (audit endpoint) response message. A second issue exists in the handling of file names sent to the Record() application which could lead to arbitrary code execution via a format string attack or arbitrary file-overwrite via directory traversal techniques. The impact of this vulnerability is minimal, however, as it requires an administrator to use a client-controlled variable as part of the filename. Solution: Mu Security would like to thank the Asterisk security team for their timely response to these issues. A patch for the buffer overflow is available from the following link: http://ftp.digium.com/pub/asterisk/asterisk-1.2.11-patch.gz To protect against the Record() vulnerability, do not use user-controlled variables ( eg, ${CALLERIDNAME} ) as part of the the filename argument. History: 08/10/06 - First contact with vendor 08/16/06 - Vendor acknowledges vulnerability 08/23/06 - Advisory released Credit: These vulnerabilities were discovered by the Mu Security research team. http://labs.musecurity.com/pgpkkey.txt Mu Security offers a new class of security analysis system, delivering a rigorous and streamlined methodology for verifying the robustness and security readiness of any IP-based product or application.

I have updated the ebuilds and patches for zaptel-1.2.8 and asterisk-1.2.11. However, since I am not a maintainer of these packages, I just have them local (and tested on x86 and amd64). I tried to contact stkn and rajiv today. If security would like me to bump these for the security fixes over asterisk-1.2.9, let me know. I can then commit them to cvs. Jay
As this also fixes bug #141551 I think you should go ahead.
i maintain only asterisk 1.0.x and have not heard from stkn. i suggest you bump the ebuild if you can install and test it. thanks.
hi jay, hi jay, I would like to test your ebuilds, too. Can you send or atach your ebuilds to this bug?

I uploaded the ebuild to my dev space. See http://dev.gentoo.org/~pfeifer/asterisk/ Just grab the 2 tbz2s or you can get the ebuilds under the net-misc dir (as well as the zaptel patch) Jay
Jay/Rajiv could you commit the updated ebuilds so we can call arch teams?

We have a fix committed: 06 Sep 2006; Stefan Knoblich <stkn@gentoo.org> +asterisk-1.2.11.ebuild: Arches please test and mark stable. Target keywords are: asterisk-1.2.11.ebuild:KEYWORDS="~alpha ~amd64 ~hppa ~ppc sparc x86"
sparc stable. on a side note it works fine on a couple x86 servers i handle (E1/FXO/FXS mostly) and people might want to take care of bug #145783 before too.

Version 1.2.11 compiles great, but have a Bug (Pickup). 1.2.12.1 and Zaptel 1.2.9.1 are out now.
Back to ebuild to fix the regression. UnCC'ing arches.
voip any news on this one?
this is kinda annoying... no info on the bug for more than 2 weeks... any news from voip??? asterisk-1.2.12.1 has been uploaded today... i guess we can go for stable marking then?
yeah I moved it from the overlay to portage after talking with stkn. I guess marking it stable should be fine - go ahead.
btw, this has been rated C1... according to the policy that results in a target delay of 5 days sparc, x86 pls test net-misc/asterisk-1.2.12.1 and mark stable if possible
even adding arches to CC now ;)
sparc stable.
