"Multiple vulnerabilities have been discovered in uriparser, an Uniform
Resource Identifiers (URIs) parsing library.

CVE-2018-19198

UriQuery.c allows an out-of-bounds write via a uriComposeQuery* or
uriComposeQueryEx* function because the '&' character is mishandled in
certain contexts.

CVE-2018-19199

UriQuery.c allows an integer overflow via a uriComposeQuery* or
uriComposeQueryEx* function because of an unchecked multiplication.

CVE-2018-19200

UriCommon.c allows attempted operations on NULL input via a
uriResetUri* function.

For Debian 8 'Jessie', these problems have been fixed in version
0.8.0.1-2+deb8u1.

We recommend that you upgrade your uriparser packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
