Description

The remote host is affected by the vulnerability described in GLSA-201203-21 (Asterisk: Multiple vulnerabilities)

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.
