| Package | Affected versions | Patched versions |
|---|---|---|
| php | ≥ 8.1.0, < 8.1.29≥ 8.2.0, < 8.2.20≥ 8.3.0, < 8.3.8 | 8.1.298.2.208.3.8 |
In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, when using Apache and PHP-CGI on Windows, if the system is set up to use certain code pages, Windows may use "Best-Fit" behavior to replace characters in command line given to Win32 API functions. PHP CGI module may misinterpret those characters as PHP options, which may allow a malicious user to pass options to PHP binary being run, and thus reveal the source code of scripts, run arbitrary PHP code on the server, etc.
