    Package        : php7.4
    Version        : 7.4.33-1+deb11u10
    CVE ID         : CVE-2025-14178
    Debian Bug     : 1123574

    Multiple security issues were found in PHP, a widely-used open source
    general purpose scripting language, which could result in server side
    request forgery or denial of service.

    CVE-2025-14178

        Heap buffer overflow in array_merge().

    GHSA-www2-q4fc-65wf

        dns_get_record() and other DNS functions don't have any null contain
        check, which may lead to SSRF or unexpected behavior.  While this
        has a (low) security impact, no CVE ID was assigned for this
        vulnerability yet.

    For Debian 11 bullseye, these problems have been fixed in version
    7.4.33-1+deb11u10.

    We recommend that you upgrade your php7.4 packages.

    For the detailed security status of php7.4 please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/php7.4
