SUSE update for postgresql16

1) Input validation error

EUVDB-ID: #VU103970

Risk: Critical

CVSSv4.0: 9.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Red]

CVE-ID: CVE-2025-1094

CWE-ID: CWE-20 - Improper input validation

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to execute arbitrary SQL queries in the database.

The vulnerability exists due to insufficient validation of quoting syntax in PostgreSQL libpq functions PQescapeLiteral(), PQescapeIdentifier(), PQescapeString(), and PQescapeStringConn() and within the command line utility programs  when client_encoding is BIG5 and server_encoding is one of EUC_TW or MULE_INTERNAL. A remote attacker can pass specially crafted input to the application and execute arbitrary SQL queries in the database.

Note, the vulnerability is being actively exploited in the wild.

Mitigation

Update the affected package postgresql16 to the latest version.
