Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED12 / SLES12 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2021:2564-1 advisory.

 - In PHP versions 7.3.x below 7.3.29, 7.4.x below 7.4.21 and 8.0.x below 8.0.8, when using URL validation functionality via filter_var() function with FILTER_VALIDATE_URL parameter, an URL with invalid password field can be accepted as valid. This can lead to the code incorrectly parsing the URL and potentially leading to other security implications - like contacting a wrong server or making a wrong access decision.
