URI_FUNC() in UriParse.c in uriparser before 0.9.1 has an out-of-bounds read (in uriParse*Ex* functions) for an incomplete URI with an IPv6 address containing an embedded IPv4 address, such as a "//[::44.1" address.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - uriparser: Out-of-bounds read in uriParse*Ex* (CVE-2018-20721)

  - An issue was discovered in uriparser before 0.9.0. UriCommon.c allows attempted operations on NULL input     via a uriResetUri* function. (CVE-2018-19200)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5172-2 advisory.

    USN-5172-1 fixed vulnerabilities in uriparser. This update provides the corresponding updates for Ubuntu     14.04 ESM and Ubuntu 16.04 ESM.

The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5172-1 advisory.

    It was discovered that uriparser mishandled certain input. An attacker could use this vulnerability to     cause uriparser to crash or possibly execute arbitrary code. (CVE-2018-19198, CVE-2018-19199,     CVE-2018-19200)

    It was discovered that uriparser incorrectly handled certain URIs. An attacker could use this     vulnerability to cause a crash or possibly leak sensitive information. (CVE-2018-20721)

The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-2834 advisory.

  - URI_FUNC() in UriParse.c in uriparser before 0.9.1 has an out-of-bounds read (in uriParse*Ex* functions)     for an incomplete URI with an IPv6 address containing an embedded IPv4 address, such as a //[::44.1     address. (CVE-2018-20721)

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

Joergen Ibsen reported an issue with uriparser, a URI parsing library compliant with RFC 3986.

An Out-of-bounds read for incomplete URIs with IPv6 addresses with embedded IPv4 address, e.g. '//[::44.1', were possible.

For Debian 8 'Jessie', this problem has been fixed in version 0.8.0.1-2+deb8u2.

We recommend that you upgrade your uriparser packages.
