EulerOS Virtualization 2.10.0 : python-ldap (EulerOS-SA-2022-2914)

medium Nessus Plugin ID 169400


The remote EulerOS Virtualization host is missing a security update.


According to the versions of the python-ldap package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- python-ldap before 3.4.0 is vulnerable to a denial of service when ldap.schema is used for untrusted schema definitions, because of a regular expression denial of service (ReDoS) flaw in the LDAP schema parser. By sending crafted regex input, a remote authenticated attacker could exploit this vulnerability to cause a denial of service condition. (CVE-2021-46823)

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.


Update the affected python-ldap packages.
