CyberRota Analysis
AI-GeneratedPostgreSQL's ECPG client is vulnerable to an integer underflow that can lead to a temporary denial of service when a database server administrator sends a malformed bytea value. This flaw allows the client to overwrite a significant memory region, potentially causing a SIGSEGV, and in rare instances, may lead to integrity issues specific to the client. Database administrators using affected versions prior to 18.5, 17.11, 16.15, 15.19, and 14.24 should prioritize applying updates to mitigate this risk.
Original NVD Description
Integer underflow in PostgreSQL ECPG allows a database server administrator to achieve temporary denial of service against the ECPG client via sending a bytea value lacking the mandatory prefix. The client overwrites a huge memory region with bytes outside attacker knowledge or control. This typically yields a simple SIGSEGV, but rare cases might achieve client-specific integrity impact via the write. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.
