Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS : Apache::Session::LDAP vulnerability (USN-6596-1)

high Nessus Plugin ID 189459

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-6596-1 advisory.

 It was discovered that Apache::Session::LDAP incorrectly handled invalid X.509 certificates. If a user or an automated system were tricked into opening a specially crafted invalid X.509 certificate, a remote attacker could possibly use this issue to perform spoofing and obtain sensitive information.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected libapache-session-ldap-perl package.
