NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql15-docs package and not the postgresql15-docs package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

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 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
