Severity: high
Exploitable: remote
Date: March 28, 2012
Bug(s): #408431
ID: 201203-21
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: net-misc/asterisk
Vulnerable: < 1.8.10.1
Unaffected: >= 1.8.10.1
Architectures: All supported architectures
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: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/asterisk-1.8.10.1"
