Synopsis

Multiple vulnerabilities in Asterisk might allow remote attackers to 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 Architecture(s)
net-misc/asterisk < 1.2.37 >= 1.2.37 All supported architectures

Description

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 implementation (CVE-2009-2346).

Resolution

All Asterisk users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-misc/asterisk-1.2.37"
