CVE Name Pending

Description The Asterisk module res_pjsip_acl provides the ability to
configure ACLs that may be used to reject SIP requests from
various hosts. In affected versions of Asterisk, this
module fails to create and apply ACLs defined in
pjsip.conf. This may be worked around by reloading
res_pjsip manually after res_pjsip_acl is loaded.

Resolution The PJSIP ACL code has been changed to create and apply the
ACLs properly at startup.
