postgresql: PostgreSQL: Denial of Service via uncontrolled recursion in SSL/GSS negotiation

A flaw was found in PostgreSQL. Uncontrolled recursion during SSL Secure Sockets Layer and GSS Generic Security Service negotiation allows an attacker to achieve a sustained denial of service. This can be exploited by an attacker with access to a PostgreSQL AFUNIX socket. If SSL and GSS are both...

postgresql: PostgreSQL: Information disclosure via buffer over-read in pg_restore_attribute_stats()

A flaw was found in PostgreSQL. This buffer over-read vulnerability in the pgrestoreattributestats function allows a table maintainer to infer memory values. By providing array values of unmatched length, a malicious table maintainer can cause query planning to read past the end of an array,...

postgresql: PostgreSQL CREATE TYPE does not check multirange schema CREATE privilege

A flaw was found in PostgreSQL CREATE TYPE handling for multirange types. The database failed to properly verify schema CREATE privileges during multirange type creation. An authenticated database user could exploit this issue to hijack queries that rely on searchpath resolution for user-defined ...

postgresql: PostgreSQL: Operating system account hijack via symlink following in pg_basebackup and pg_rewind

A flaw was found in PostgreSQL. This vulnerability, related to symlink following in pgbasebackup plain format and pgrewind, allows an origin superuser to overwrite local files. By exploiting this, an attacker could potentially hijack the operating system account. This attack has practical...

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...

postgresql: PostgreSQL: Arbitrary code execution vulnerability in 'refint' module

A flaw was found in PostgreSQL. A stack buffer overflow in the 'refint' module allows an unprivileged database user to execute arbitrary code as the operating system user running the database. Additionally, a separate vulnerability exists where, if an application uses a user-controlled column as ...
