This update for postgresql18 fixes the following issues:
Update to version 18.2.
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).

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.

Описание
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.

Описание
Heap buffer overflow in PostgreSQL pg_trgm allows a database user to achieve unknown impacts via a crafted input string. The attacker has limited control over the byte patterns to be written, but we have not ruled out the viability of attacks that lead to privilege escalation. PostgreSQL 18.1 and 18.0 are affected.
