The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 05d311bc-9991-11f1-bc50-6cc21735f730 advisory.

    The PostgreSQL project reports:

              CVE-2026-6464: psql COPY FROM STDIN, if the copy fails               before data rows begin, processes the following data lines               as psql commands.

              CVE-2026-6471: Logical decoding lets a REPLICATION-               privileged user dlopen an arbitrary file via the decoding               plugin choice, running arbitrary code as the server's OS               user.


              CVE-2026-14662: Integer wraparound in tsvector and tsquery               functions can undersize an allocation, causing a buffer               overflow and arbitrary code execution.


              CVE-2026-14663: pgcrypto silently encrypts to and decrypts               from cleartext for ciphers OpenSSL has disabled, letting an               attacker recover cleartext.

              CVE-2026-14668: Type confusion in the ctid selectivity               estimator discloses a derivative of an arbitrary 4-byte span               of server memory.


              CVE-2026-14669: Heap buffer overflow in to_char(timestamptz)               via a long POSIX timezone abbreviation allows arbitrary code               execution.


              CVE-2026-14670: Heap buffer overflow in plperl, on return of               a tied hash, allows the function owner to execute arbitrary               code.


              CVE-2026-14671: Type confusion in module refint allows an               object creator to execute arbitrary code.


              CVE-2026-14672: SCRAM authentication reveals whether a role               exists via an observable difference in the reported               iteration count.


              CVE-2026-14673: amcheck fails to clear an untrusted search               path, letting an EXECUTE grantee run arbitrary functions as               an expression index's owner.


              CVE-2026-14676: Heap buffer overflow in pg_stat_statements               via crafted queries with array constants allows arbitrary               code execution.


              CVE-2026-14677: Integer wraparound in 32-bit pltcl/plperl               builds can undersize an allocation, allowing arbitrary code               execution.


              CVE-2026-14678: pg_trgm's picksplit function reads past the               end of a heap buffer, potentially disclosing limited memory.


              CVE-2026-14679: Stack buffer overflow in argument-name               matching lets an object creator write a few attacker-               influenced bytes into server memory.


              CVE-2026-14680: Type confusion via internal-typed function               arguments allows any user to execute arbitrary code.


              CVE-2026-14681: GSSAPI encryption is not properly enforced               when coupled with an initial direct SSL connection.


              CVE-2026-15741: Expression deparse of EXTRACT() allows SQL               injection via a hostile object definition, affecting pg_dump               and psql.


              CVE-2026-15742: Integer wraparound in fuzzystrmatch's               levenshtein() functions allows writes to arbitrary addresses               and code execution.


              CVE-2026-16238: Type confusion in               pg_restore_attribute_stats() allows arbitrary code execution               via conflated range/multirange values.


              CVE-2026-16239: Type confusion via cursor DECLARE and CLOSE               allows a user to execute arbitrary code.


              CVE-2026-16241: Integer underflow in ECPG can crash the               client via a bytea value lacking its mandatory prefix.


              CVE-2026-18024: The ascii() function reads past the end of a               buffer, disclosing a few bytes of server memory.


              CVE-2026-18408: psql's \unrestrict lets a malicious pg_dump               origin-server superuser execute arbitrary code in the               restoring client.


              CVE-2026-19385: Heap buffer overflow in pg_dump, when               dumping long function transform lists, allows arbitrary code               execution.
