EulerOS Virtualization 3.0.2.6 : libldb (EulerOS-SA-2021-2896)

high Nessus Plugin ID 156497

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

 - A flaw was found in samba. Spaces used in a string around a domain name (DN), while supposed to be ignored, can cause invalid DN strings with spaces to instead write a zero-byte into out-of-bounds memory, resulting in a crash. The highest threat from this vulnerability is to system availability.
 (CVE-2020-27840)

 - A flaw was found in Samba's libldb. Multiple, consecutive leading spaces in an LDAP attribute can lead to an out-of-bounds memory write, leading to a crash of the LDAP server process handling the request. The highest threat from this vulnerability is to system availability. (CVE-2021-20277)

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.

Solution

Update the affected libldb packages.
