According to the versions of the 389-ds-base packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  • race condition on reference counter leads to DoS using persistent search (CVE-2018-10850)

  • ldapsearch with server side sort allows users to cause a crash (CVE-2018-10935)

  • Server crash through modify command with large DN (CVE-2018-14624)

  • Crash in delete_passwdPolicy when persistent search connections are terminated unexpectedly (CVE-2018-14638)

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.
