Title: Asterisk: Multiple vulnerabilities (GLSA 201006-20)
Date: June 04, 2010
Bug(s): #281107, #283624, #284892, #295270
Multiple vulnerabilities in Asterisk might allow remote attackers to cause
a Denial of Service condition, or conduct other attacks.
Asterisk is an open source telephony engine and toolkit.
Vulnerable: < 1.2.37
Unaffected: >= 1.2.37
Architectures: All supported architectures
Multiple vulnerabilities have been reported in Asterisk:
- Nick Baggott reported that Asterisk does not properly process
overly long ASCII strings in various packets (CVE-2009-2726).
- Noam Rathaus and Blake Cornell reported a flaw in the IAX2 protocol
- amorsen reported an input
processing error in the RTP protocol implementation
- Patrik Karlsson reported an information
disclosure flaw related to the REGISTER message (CVE-2009-3727).
library, related to AJAX calls (CVE-2008-7220).
A remote attacker could exploit these vulnerabilities by sending a
specially crafted package, possibly causing a Denial of Service
condition, or resulting in information disclosure.
There is no known workaround at this time.
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
already no longer affected by this issue.
