    Package        : php7.3
    Version        : 7.3.31-1~deb10u7
    CVE ID         : CVE-2024-5458
    Debian Bug     : 1072885

    PHP, a widely-used open source general purpose scripting language, is affected
    by a security problem when parsing certain types of URLs.

    Due to a code logic error filtering functions such as filter_var when
    validating URLs (FILTER_VALIDATE_URL) will result 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. The problem is related to CVE-2020-7071 but affects
    IPv6 host parts.

    For Debian 10 buster, this problem has been fixed in version
    7.3.31-1~deb10u7.

    We recommend that you upgrade your php7.3 packages.

    For the detailed security status of php7.3 please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/php7.3
