Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:0881-1 advisory.

 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'.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
