Description - taken from upstream avisory: A missing ACL check for handling SIP INVITEs allows a device to make calls on networks intended to be prohibited as defined by the "deny" and "permit" lines in sip.conf. The ACL check for handling SIP registrations was not affected. Affected: 1.6.x Corrected in: 1.6.1.8

Contrary to a prior posting, this vulnerability only affects the 1.6.1.x branch of Asterisk, not 1.6.x as a whole. All vulnerable ebuilds have been purged from the tree, 1.6.1.8 has been added. As all these ebuilds are hardmasked in the tree (and the stable 1.2 ebuilds are not all affected), a GLSA will not be issued. Closing bug.
