A Denial Of Service vulnerability in MiniUPnP MiniUPnPd through 2.1 exists due to a NULL pointer dereference in copyIPv6IfDifferent in pcpserver.c.

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

  - A Denial Of Service vulnerability in MiniUPnP MiniUPnPd through 2.1 exists due to a NULL pointer     dereference in copyIPv6IfDifferent in pcpserver.c. (CVE-2019-12111)

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

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - The upnp_event_prepare function in upnpevents.c in MiniUPnP MiniUPnPd through 2.1 allows a remote attacker
    to leak information from the heap due to improper validation of an snprintf return value. (CVE-2019-12107)

  - A Denial Of Service vulnerability in MiniUPnP MiniUPnPd through 2.1 exists due to a NULL pointer
    dereference in GetOutboundPinholeTimeout in upnpsoap.c for int_port. (CVE-2019-12108)

  - A Denial Of Service vulnerability in MiniUPnP MiniUPnPd through 2.1 exists due to a NULL pointer
    dereference in GetOutboundPinholeTimeout in upnpsoap.c for rem_port. (CVE-2019-12109)

  - An AddPortMapping Denial Of Service vulnerability in MiniUPnP MiniUPnPd through 2.1 exists due to a NULL
    pointer dereference in upnpredirect.c. (CVE-2019-12110)

  - A Denial Of Service vulnerability in MiniUPnP MiniUPnPd through 2.1 exists due to a NULL pointer
    dereference in copyIPv6IfDifferent in pcpserver.c. (CVE-2019-12111)

The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4542-1 advisory.

    It was discovered that MiniUPnPd did not properly validate callback addresses. A remote attacker could     possibly use this issue to expose sensitive information. (CVE-2019-12107)

    It was discovered that MiniUPnPd incorrectly handled unpopulated user XML input. An attacker could     possibly use this issue to cause MiniUPnPd to crash, resulting in a denial of service. (CVE-2019-12108,     CVE-2019-12109)

    It was discovered that MiniUPnPd incorrectly handled an empty description when port mapping. An attacker     could possibly use this issue to cause MiniUPnPd to crash, resulting in a denial of service.
    (CVE-2019-12110)

    It was discovered that MiniUPnPd did not properly parse certain PCP requests. An attacker could possibly     use this issue to cause MiniUPnPd to crash, resulting in a denial of service. (CVE-2019-12111)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Security patches.

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Ben Barnea and colleagues from VDOO discovered several vulnerabilities in miniupnpd, a small daemon that provides UPnP Internet Gateway Device and Port Mapping Protocol services. The issues are basically information leak, NULL pointer dereferences and uses after free.

For Debian 8 'Jessie', these problems have been fixed in version 1.8.20140523-4+deb8u1.

We recommend that you upgrade your miniupnpd packages.
