Amazon Linux AMI : php72, php73 (ALAS-2020-1397)

medium Nessus Plugin ID 138639

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The version of php72 installed on the remote host is prior to 7.2.31-1.23. The version of php73 installed on the remote host is prior to 7.3.19-1.26. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1397 advisory.

 In PHP versions 7.2.x below 7.2.31, 7.3.x below 7.3.18 and 7.4.x below 7.4.6, when HTTP file uploads are allowed, supplying overly long filenames or field names could lead PHP engine to try to allocate oversized memory storage, hit the memory limit and stop processing the request, without cleaning up temporary files created by upload request. This potentially could lead to accumulation of uncleaned temporary files exhausting the disk space on the target server. (CVE-2019-11048)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'yum update php72' to update your system.
 Run 'yum update php73' to update your system.
