cause a Denial of Service condition, or conduct other attacks.
Background
==========
Asterisk is an open source telephony engine and toolkit.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------

overly long ASCII strings in various packets (CVE-2009-2726).
* Noam Rathaus and Blake Cornell reported a flaw in the IAX2 protocol
implementation (CVE-2009-2346).

specially crafted package, possibly causing a Denial of Service
condition, or resulting in information disclosure.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Asterisk users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/asterisk-1.2.37"
NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since January 5, 2010. It is likely that your system is
