9 January 2024
Several security issues were fixed in PostgreSQL.
Releases
Packages
- postgresql-9.5 - Object-relational SQL database
Details
Pedro Gallegos discovered that PostgreSQL incorrectly handled modifying
certain SQL array values. A remote attacker could use this issue to obtain
sensitive information, or possibly execute arbitrary code. (CVE-2023-5869)
Hemanth Sandrana and Mahendrakar Srinivasarao discovered that PostgreSQL
allowed the pg_signal_backend role to signal certain superuser processes,
contrary to expectations. (CVE-2023-5870)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04
-
postgresql-9.5
-
9.5.25-0ubuntu0.16.04.1+esm6
Available with Ubuntu Pro
-
postgresql-client-9.5
-
9.5.25-0ubuntu0.16.04.1+esm6
Available with Ubuntu Pro
After a standard system update you need to restart PostgreSQL to make
all the necessary changes.
