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 ...

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 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 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 SQL execution via SQL injection in logical replication

A flaw was found in PostgreSQL. This SQL injection vulnerability exists within the logical replication feature, specifically when using the ALTER SUBSCRIPTION ... REFRESH PUBLICATION command. A malicious subscriber table creator can exploit this flaw to execute arbitrary SQL commands with the...

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: Credential recovery via covert timing channel in MD5 password comparison

A flaw was found in PostgreSQL. This vulnerability, a covert timing channel, exists in the comparison of MD5-hashed passwords during authentication. A remote attacker could exploit this to recover user credentials, gaining unauthorized access to the database. This issue specifically impacts...

Important: Red Hat Security Advisory: postgresql:16 security update

An update for the postgresql:16 module is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each...

postgresql: PostgreSQL: Information disclosure via externally-controlled format string in timeofday() function

A flaw was found in PostgreSQL. This vulnerability, an externally-controlled format string in the timeofday function, allows a remote attacker to craft specific timezone zones. Successful exploitation can lead to the retrieval of sensitive portions of server memory, potentially disclosing...

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: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...

Important: Red Hat Security Advisory: postgresql:15 security update

An update for the postgresql:15 module is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each...
