    Package        : php7.4     Version        : 7.4.33-1+deb11u6     CVE ID         : CVE-2022-4900 CVE-2024-5458 CVE-2024-8925 CVE-2024-8927                      CVE-2024-9026     Debian Bug     : 1072885

    Multiple security issues were found in PHP, a widely-used open source     general purpose scripting language, which could result in execution of     arbitrary code, erroneous parsing of invalid URLs or multipart form     data, configuration setting bypass, or log pollution.

    CVE-2022-4900

        It was discovered that setting the environment variable         PHP_CLI_SERVER_WORKERS to a large value leads to a heap buffer         overflow.

    CVE-2024-5458

        Due to a code logic error, filtering functions such as filter_var         when validating URLs (FILTER_VALIDATE_URL) for certain types of URLs         the function results in invalid user information (username +         password part of URLs) being treated as valid user information.
        This may lead to the downstream code accepting invalid URLs as valid         and parsing them incorrectly.

        This causes the same problems as CVE-2020-7071, but with IPv6 host         parts.

    CVE-2024-8925

        Mihail Kirov discovered an erroneous parsing of multipart form data         contained in an HTTP POST request, which could lead to legitimate         data not being processed thereby violating data integrity.

    CVE-2024-8927

        It was discovered that the `cgi.force_redirect` configuration         setting is bypassable due to environment variable collision.

    CVE-2024-9026

        In PHP-FPM, when configured to catch workers output through         catch_workers_output = yes configuration, it may be possible to         pollute the final log with up to 4 characters from the         FPM_STDIO_CMD_FLUSH macro, or remove up to 4 characters from the         logs.

    For Debian 11 bullseye, these problems have been fixed in version     7.4.33-1+deb11u6.

    We recommend that you upgrade your php7.4 packages.
