Amazon Linux AMI : php72 (ALAS-2020-1367)

high Nessus Plugin ID 136628

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 7.2.30-1.22. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1367 advisory.

 In PHP versions 7.2.x below 7.2.9, 7.3.x below 7.3.16 and 7.4.x below 7.4.34, while parsing EXIF data with exif_read_data() function, it is possible for malicious data to cause PHP to read one byte of uninitialized memory. This could potentially lead to information disclosure or crash. (CVE-2020-7064)

 In PHP versions 7.2.x below 7.2.29, 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while using get_headers() with user-supplied URL, if the URL contains zero (\0) character, the URL will be silently truncated at it.
 This may cause some software to make incorrect assumptions about the target of the get_headers() and possibly send some information to a wrong server. (CVE-2020-7066)

 In PHP versions 7.2.x below 7.2.30, 7.3.x below 7.3.17 and 7.4.x below 7.4.5, if PHP is compiled with EBCDIC support (uncommon), urldecode() function can be made to access locations past the allocated memory, due to erroneously using signed numbers as array indexes. (CVE-2020-7067)

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.
