AI-Generated

A buffer over-read vulnerability in the PostgreSQL ascii() SQL function can allow an attacker to disclose up to 3 bytes of memory beyond the allocated buffer by using a specially crafted text value. While this issue is similar to a previously fixed vulnerability, its impact is considered lower. Database administrators using affected versions prior to PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 should prioritize patching to mitigate potential information disclosure risks.
