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

Several vulnerabilities were discovered in OpenLDAP, a free implementation of the Lightweight Directory Access Protocol. An unauthenticated remote attacker can take advantage of these flaws to cause a denial of service (slapd daemon crash, infinite loops) via specially crafted packets.

For Debian 9 stretch, these problems have been fixed in version 2.4.44+dfsg-5+deb9u7.

We recommend that you upgrade your openldap packages.

    This flaw allows an attacker who sends a malicious     packet processed by OpenLDAP to force a failed     assertion in csnNormalize23(). The highest threat from     this vulnerability is to system     availability.(CVE-2020-25710)

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 remote host is running a version of macOS / Mac OS X that is 11.x prior to 11.4 Big Sur. It is, therefore, affected by multiple vulnerabilities including the following:

 - A remote attacker may be able to cause unexpected application termination or arbitrary code execution.
    (CVE-2021-30712)

  - A remote attacker may be able to cause unexpected application termination or arbitrary code execution.
    (CVE-2021-30678)

  - An application may be able to execute arbitrary code with kernel privileges. (CVE-2021-30704)

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

A flaw was discovered in OpenLDAP before 2.4.57 leading to a double free and slapd crash in the saslAuthzTo processing, resulting in denial of service.
