    Multiple vulnerabilities have been discovered in OpenSLP. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could possibly cause a Denial of Service condition or       have other unspecified impacts.
  Workaround :

    There is no known workaround at this time.

According to the versions of the openslp packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Buffer overflow in the SLPFoldWhiteSpace function in     common/slp_compare.c in OpenSLP 2.0 allows remote     attackers to have unspecified impact via a crafted     string.(CVE-2016-7567)

  - The _xrealloc function in xlsp_xmalloc.c in OpenSLP     2.0.0 allows remote attackers to cause a denial of     service (NULL pointer dereference and crash) via a     large number of crafted packets, which triggers a     memory allocation failure.(CVE-2016-4912)

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

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