Title
PostgreSQL libpq lo_* functions let server superuser overwrite client stack memory
Summary
Use of inherently dangerous function PQfn(..., result_is_int=0, ...) in PostgreSQL libpq lo_export(), lo_read(), lo_lseek64(), and lo_tell64() functions allows the server superuser to overwrite a client stack buffer with an arbitrarily-large response. Like gets(), PQfn(..., result_is_int=0, ...) stores arbitrary-length, server-determined data into a buffer of unspecified size. Because both the \lo_export command in psql and pg_dump call lo_read(), the server superuser can overwrite pg_dump or psql stack memory. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

A server superuser can exploit a buffer overflow vulnerability in the PQfn function, which is used by client functions such as lo_export(), lo_read(), lo_lseek64(), and lo_tell64(). This allows the superuser to send an arbitrarily large response, overwriting the client\u0027s stack memory, specifically in tools like psql and pg_dump. This could lead to arbitrary code execution on the client system."
