"CVE-2018-12584 A flaw in function ConnectionBase::preparseNewBytes of
resip/stack/ConnectionBase.cxx has been detected, that allows remote
attackers to cause a denial of service (buffer overflow) or possibly
execute arbitrary code when TLS communication is enabled.

CVE-2017-11521 A flaw in function SdpContents::Session::Medium::parse
of resip/stack/SdpContents.cxx has been detected, that allows remote
attackers to cause a denial of service (memory consumption) by
triggering many media connections.

For Debian 8 'Jessie', these problems have been fixed in version
1:1.9.7-5+deb8u1.

We recommend that you upgrade your resiprocate packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
