Title: Asterisk: Multiple vulnerabilities (GLSA 201203-21)
Date: March 28, 2012
Multiple vulnerabilities have been found in Asterisk, the worst of
which may allow execution of arbitrary code.
Asterisk is an open source telephony engine and toolkit.
Vulnerable: < 18.104.22.168
Unaffected: >= 22.214.171.124
Architectures: All supported architectures
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).
A remote unauthenticated attacker could execute arbitrary code or cause
a Denial of Service condition.
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-126.96.36.199"
