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
Buffer overflow in get_salt_from_password from sql_acl.cc for MySQL 4.0.14 and earlier, and 3.23.x, allows attackers with ALTER TABLE privileges to execute arbitrary code via a long Password field.

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 Moderate confidence

MySQL 3.23.58 (for 3.23.x) or MySQL 4.0.15+/4.1.3+ (for 4.0.x/4.1.x)

  1. 1. Identify the exact MySQL version currently installed using: mysql --version or SELECT VERSION();
  2. 2. For MySQL 3.23.x: Upgrade to MySQL 3.23.58 (the final 3.23 release with security patches)
  3. 3. For MySQL 4.0.x: Upgrade to MySQL 4.0.15 or later (earliest version with this vulnerability fixed)
  4. 4. For MySQL 4.1.0: Upgrade to the latest 4.1.x stable release (at least 4.1.3)
  5. 5. After upgrade, verify the version: mysql --version
  6. 6. Review user privileges, as the vulnerability requires ALTER TABLE privileges - audit accounts with elevated permissions
Caveat Upgrading MySQL major versions may require schema adjustments and compatibility testing; ensure backups exist before upgrading
