The SdpContents::Session::Medium::parse function in resip/stack/SdpContents.cxx in reSIProcate 1.10.2 allows remote attackers to cause a denial of service (memory consumption) by triggering many media connections.

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

  - The SdpContents::Session::Medium::parse function in resip/stack/SdpContents.cxx in reSIProcate 1.10.2     allows remote attackers to cause a denial of service (memory consumption) by triggering many media     connections. (CVE-2017-11521)

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

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2865 advisory.

  - The SdpContents::Session::Medium::parse function in resip/stack/SdpContents.cxx in reSIProcate 1.10.2     allows remote attackers to cause a denial of service (memory consumption) by triggering many media     connections. (CVE-2017-11521)

  - The ConnectionBase::preparseNewBytes function in resip/stack/ConnectionBase.cxx in reSIProcate through     1.10.2 allows remote attackers to cause a denial of service (buffer overflow) or possibly execute     arbitrary code when TLS communication is enabled. (CVE-2018-12584)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
