Stack-based buffer overflow in the init_syms function in MySQL 4.0 before 4.0.25, 4.1 before 4.1.13, and 5.0 before 5.0.7-beta allows remote authenticated users who can create user-defined functions to execute arbitrary code via a long function_name field.

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.

Executive

CVE-2005-2558 is a medium public vulnerability record for Oracle mysql. It is not currently listed in the CISA Known Exploited catalog. Check the linked vendor or CERT advisories for patch status. This summary is a catalog interpretation of the ingested metadata and cites the original advisories below.

System administrator

Identify whether Oracle mysql is in your estate, then compare installed versions with the affected ranges. Affected packages or ranges on record: mysql/mysql (4.1.0); mysql/mysql (4.1.10); mysql/mysql (4.1.3); mysql/mysql (5.0.1). Check the linked vendor or CERT advisories for patch status. Prefer the vendor or distribution advisory linked in Sources before changing production systems. This is a catalog interpretation, not a runbook.
