An integer underflow vulnerability in PostgreSQL ECPG client allows a database server administrator to cause a temporary denial of service by sending a malformed bytea value without the required prefix. This leads to the client overwriting a large memory region, usually resulting in a segmentation fault. In rare cases, this may cause client-specific integrity issues. The vulnerability affects PostgreSQL versions prior to 18.5, 17.11, 16.15, 15.19, and 14.24.
