Synopsis ========
Multiple vulnerabilities have been found in Asterisk, the worst of which may allow execution of arbitrary code.
Background ==========
Asterisk is an open source telephony engine and toolkit.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/asterisk < 1.8.10.1 >= 1.8.10.1
Description ===========
Two vulnerabilities have been found in Asterisk:
* The "milliwatt_generate()" function in app_milliwatt.c is vulnerable to a stack overrun (AST-2012-002). * The "ast_parse_digest()" function in utils.c is vulnerable to a stack-based buffer overflow (AST-2012-003).
Impact ======
A remote unauthenticated attacker could execute arbitrary code 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-1.8.10.1"
