Vulnerability CVE-2010-1224 - CERT Civis.Net

Vulnerability Name:

CVE-2010-1224 (CCN-56552)

Assigned:

2010-02-24

Published:

2010-02-24

Updated:

2018-10-10

Summary:

main/acl.c in Asterisk Open Source 1.6.0.x before 1.6.0.25, 1.6.1.x before 1.6.1.17, and 1.6.2.x before 1.6.2.5 does not properly enforce remote host access controls when CIDR notation "/0" is used in permit= and deny= configuration rules, which causes an improper arithmetic shift and might allow remote attackers to bypass ACL rules and access services from unauthorized hosts.
