AI-suggested

Red Hat has released updated packages for PostgreSQL 16 that address these vulnerabilities. Users of Red Hat Enterprise Linux 10 and related variants should apply the security update as soon as possible. Detailed instructions for applying the update are available at https://access.redhat.com/articles/11258. Since this is an official security advisory with an available update, applying the vendor-provided patch is the primary recommended mitigation.

Description

Multiple security vulnerabilities have been identified in PostgreSQL 16 as packaged for Red Hat Enterprise Linux 10. These include missing validation of multibyte character length, missing validation of input type to the intarray selectivity estimator, and a heap buffer overflow in the pgcrypto module. These issues can lead to arbitrary code execution. Red Hat has released an important security update addressing these vulnerabilities for various architectures and variants of Red Hat Enterprise Linux 10 and CodeReady Linux Builder 10.
