Amazon Linux AMI : php72, php73 (ALAS-2020-1440)

medium Nessus Plugin ID 141980

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 7.2.34-1.26. The version of php73 installed on the remote host is prior to 7.3.23-1.29. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1440 advisory.

In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when AES-CCM mode is used with openssl_encrypt() function with 12 bytes IV, only first 7 bytes of the IV is actually used. This can lead to both decreased security and incorrect encryption data. (CVE-2020-7069)

In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when PHP is processing incoming HTTP cookie values, the cookie names are url-decoded. This may lead to cookies with prefixes like
__Host confused with cookies that decode to such prefix, thus leading to an attacker being able to forge cookie which is supposed to be secure. See alsoCVE-2020-8184for more information. (CVE-2020-7070)

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

Note that Nessus has not tested for these issues 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.
