Description GLSAMaker/CVETool Bot gentoo-dev 2018-01-25 15:55:34 UTC 
CVE-2017-17850 (https://nvd.nist.gov/vuln/detail/CVE-2017-17850):
  An issue was discovered in Asterisk 13.18.4 and older, 14.7.4 and older,
  15.1.4 and older, and 13.18-cert1 and older. A select set of SIP messages
  create a dialog in Asterisk. Those SIP messages must contain a contact
  header. For those messages, if the header was not present and the PJSIP
  channel driver was used, Asterisk would crash. The severity of this
  vulnerability is somewhat mitigated if authentication is enabled. If
  authentication is enabled, a user would have to first be authorized before
  reaching the crash point.
