postgresql: PostgreSQL libpq: Buffer overflow allows server superuser to overwrite client stack memory

A flaw was found in PostgreSQL libpq. A server superuser can exploit a buffer overflow vulnerability in the PQfn function, which is used by client functions such as loexport, loread, lolseek64, and lotell64. This allows the superuser to send an arbitrarily large response, overwriting the client's...
