Security update for postgresql16
This update for postgresql16 fixes the following issues:
Update to version 16.13 (bsc#1258754).
Security issues fixed:
- CVE-2026-2003: improper validation of type 'oidvector' may allow disclose a few bytes of server memory (bsc#1258008).
- CVE-2026-2004: intarray missing validation of type of input to selectivity estimator could lead to arbitrary code execution (bsc#1258009).
- CVE-2026-2005: buffer overrun in contrib/pgcrypto's PGP decryption functions could lead to arbitrary code execution (bsc#1258010).
- CVE-2026-2006: inadequate validation of multibyte character lengths could lead to arbitrary code execution (bsc#1258011).
Regression fixes:
- the substring() function raises an error 'invalid byte sequence for encoding' on non-ASCII text values if the source of that value is a database column (caused by CVE-2026-2006 fix).
- a standby may halt and return an error 'could not access status of transaction'.

Описание
Improper validation of type "oidvector" in PostgreSQL allows a database user to disclose a few bytes of server memory. We have not ruled out viability of attacks that arrange for presence of confidential information in disclosed bytes, but they seem unlikely. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected.

Missing validation of type of input in PostgreSQL intarray extension selectivity estimator function allows an object creator to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected.

Heap buffer overflow in PostgreSQL pgcrypto allows a ciphertext provider to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected.

Описание
Missing validation of multibyte character length in PostgreSQL text manipulation allows a database user to issue crafted queries that achieve a buffer overrun. That suffices to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected.
