Description

The version of php72 installed on the remote host is prior to 7.2.33-1.25. The version of php73 installed on the remote host is prior to 7.3.21-1.28. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1425 advisory.

 - In PHP versions 7.2.x below 7.2.33, 7.3.x below 7.3.21 and 7.4.x below 7.4.9, while processing PHAR files using phar extension, phar_parse_zipfile could be tricked into accessing freed memory, which could lead to a crash or information disclosure. (CVE-2020-7068)
