An update that solves two vulnerabilities can now be installed.

Description:

This update for postgresql16 fixes the following issues:

Security fixes:

• CVE-2025-12817: Missing check for CREATE privileges on the schema in CREATE STATISTICS allowed table owners to create statistics in any schema, potentially leading to unexpected naming conflicts (bsc#1253332)
• CVE-2025-12818: Several places in libpq were not sufficiently careful about computing the required size of a memory allocation. Sufficiently large inputs could cause integer overflow, resulting in an undersized buffer, which would then lead to writing past the end of the buffer (bsc#1253333)

Other fixes:

• Upgrade to 16.11
