"According to the versions of the php packages installed, the EulerOS Virtualization installation on the remote host is
affected by the following vulnerabilities :

  - In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when using Postgres
    database extension, supplying invalid parameters to the parametrized query may lead to PHP attempting to
    free memory using uninitialized data as pointers. This could lead to RCE vulnerability or denial of
    service. (CVE-2022-31625)

  - In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when pdo_mysql extension
    with mysqlnd driver, if the third party is allowed to supply host to connect to and the password for the
    connection, password of excessive length can trigger a buffer overflow in PHP, which can lead to a remote
    code execution vulnerability. (CVE-2022-31626)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
