PHP 7.3.x < 7.3.16 Multiple Vulnerabilities

high Nessus Plugin ID 134944

Synopsis

The version of PHP running on the remote web server is affected by multiple vulnerabilities.

Description

According to its banner, the version of PHP running on the remote web server is 7.3.x prior to 7.3.16. It is, therefore, affected by the following vulnerabilities:

 - An out of bounds read resulting in the use of an uninitialized value in exif. (CVE-2020-7064)

 - A stack buffer overflow in mb_strtolower() allows overwriting of a stack-allocated buffer with an overflown array from .rodata. (CVE-2020-7065)

 - get_headers() silently truncates anything after a null byte in the URL it uses. An unauthenticated, remote attacker can exploit this to leak sensitive information or cause the web server to unexpectedly process attacker-controlled data. (CVE-2020-7066) Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to PHP version 7.3.16 or later.
