An update that solves five vulnerabilities and has one security fix can now be
installed.
## Description:
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".
