PHP 5.6.x < 5.6.35 Security Bypass Vulnerability
Low Nessus Plugin ID 122591
SynopsisThe version of PHP running on the remote web server is affected by a security bypass vulnerability.
DescriptionAccording to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.35. It is, therefore, affected by a security bypass vulnerability. Dumpable FPM child processes allow bypassing opcache access controls because fpm_unix.c makes a PR_SET_DUMPABLE prctl call, allowing one user (in a multiuser environment) to obtain sensitive information from the process memory of a second user's PHP applications by running gcore on the PID of the PHP-FPM worker process.
SolutionUpgrade to PHP version 5.6.35 or later.
