This update for postgresql18 fixes the following issues: Update to version 18.3 (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). - CVE-2026-2007: pg_trgm heap buffer overflow can cause to write pattern onto server memory (bsc#1258012). 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'.
