The Service Location Protocol (SLP, RFC 2608) allows an unauthenticated, remote attacker to register arbitrary services. This could allow the attacker to use spoofed UDP traffic to conduct a denial-of-service attack with a significant amplification factor.

The remote Redhat Enterprise Linux 9 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

  - openslp: Reflective denial of service amplification attack via UDP (CVE-2023-29552)

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

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.

  - openslp: memory corruption due to possible overflow in SLPFoldWhiteSpace in common/slp_compare.c     (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)

  - The Service Location Protocol (SLP, RFC 2608) allows an unauthenticated, remote attacker to register     arbitrary services. This could allow the attacker to use spoofed UDP traffic to conduct a denial-of-     service attack with a significant amplification factor. (CVE-2023-29552)

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 VMware ESXi host is less than version 7.0 and is affected by a reflected denial of service vulnerability:

  - The Service Location Protocol (SLP, RFC 2608) allows an unauthenticated, remote attacker to register arbitrary     services. This could allow the attacker to use spoofed UDP traffic to conduct a denial-of-service attack with a     significant amplification factor. (CVE-2023-29552)

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