In the pjsip channel driver (res_pjsip) in Asterisk 13.x before 13.17.1 and 14.x before 14.6.1, a carefully crafted tel URI in a From, To, or Contact header could cause Asterisk to crash.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the pjsip channel driver (res_pjsip) in Asterisk 13.x before 13.17.1 and 14.x before 14.6.1, a     carefully crafted tel URI in a From, To, or Contact header could cause Asterisk to crash. (CVE-2017-14098)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote host is affected by the vulnerability described in GLSA-201710-29 (Asterisk: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Asterisk. Please review       the referenced CVE identifiers for details.
  Impact :

    A remote attacker could execute arbitrary code, cause a denial of       service condition, or cause an unauthorized data disclosure by enticing a       user to run malicious code.
  Workaround :

    There is no known workaround at this time.

According to its SIP banner, the version of Asterisk running on the remote host is 11.x prior to 11.25.2, 13.x prior to 13.17.1, 14.x prior to 14.6.1, 11.6 prior to 11.6-cert17, or 13.13 prior to 13.13-cert5. It is therefore, affected by multiple vulnerabilities as described in AST-2017-005, AST-2017-006, and AST-2017-007.

Note for AST-2017-005, only 11.4.0 is affected in the 11.x branch.

Also note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Asterisk project reports :

A carefully crafted URI in a From, To or Contact header could cause Asterisk to crash.
