Synopsis ========
Multiple vulnerabilities in Asterisk might allow remote attackers to execute arbitrary code.
Background ==========
Asterisk is an open source telephony engine and toolkit.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/asterisk < 1.8.12.1 >= 1.8.12.1
Description ===========
Multiple vulnerabilities have been found in Asterisk:
* An error in manager.c allows shell access through the MixMonitor application, GetVar, or Status (CVE-2012-2414). * An error in chan_skinny.c could cause a heap-based buffer overflow (CVE-2012-2415). * An error in chan_sip.c prevents Asterisk from checking if a channel exists before connected line updates (CVE-2012-2416). * An error in chan_iax2.c may cause an invalid pointer to be called (CVE-2012-2947). * chan_skinny.c contains a NULL pointer dereference (CVE-2012-2948).
Impact ======
A remote attacker could execute arbitrary code with the privileges of the process or cause a Denial of Service condition.
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-1.8.12.1"
