Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Recommended fix High confidence

PHP 7.4.30 (for 7.4.x line), PHP 8.0.20 (for 8.0.x line), or PHP 8.1.7 (for 8.1.x line)

  1. 1. Identify current PHP version by running: php -v
  2. 2. For PHP 7.4.x users: upgrade to PHP 7.4.30 or later
  3. 3. For PHP 8.0.x users: upgrade to PHP 8.0.20 or later
  4. 4. For PHP 8.1.x users: upgrade to PHP 8.1.7 or later
  5. 5. On Debian 10/11 systems: run 'apt-get update && apt-get install php7.4' (or appropriate version) or wait for Debian security updates
  6. 6. After upgrade, verify the fix by running: php -v and confirm the version number matches or exceeds the fixed release
  7. 7. Restart any running PHP-FPM or Apache processes to load the new version
Caveat Minor point releases within the same major.minor version typically contain only bug fixes and security patches; however, always review the PHP migration guide if jumping between major versions (e.g., 7.4 to 8.0)
