BEEP protocol dissector crash in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service

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 7185ecc9-4fb7-11f1-bc50-6cc21735f730 advisory.

    The PostgreSQL project reports:

              Missing authorization in PostgreSQL CREATE TYPE               allows an object creator to hijack other queries that use               search_path to find user-defined types, including               extension-defined types. That is to say, the victim will execute               arbitrary SQL functions of the attacker's choice.


              Integer wraparound in multiple PostgreSQL server               features allows an application input provider to cause the               server to undersize an allocation and write out-of-bounds. This               results in a segmentation fault.


              Externally-controlled format string in PostgreSQL timeofday()               function allows an attacker to retrieve portions of server               memory, via crafted timezone zones.


              Symlink following in               PostgreSQL pg_basebackup plain format and in pg_rewind allows an               origin superuser to overwrite local files, e.g.
              /var/lib/postgres/.bashrc, that hijack the operating system               account. It will remain the case that starting the server after               these commands implicitly trusts the origin superuser, due to               features like shared_preload_libraries. Hence, the attack has               practical implications only if one takes relevant action between               these commands and server start, like moving the files to a               different VM or snapshotting the VM.


              SQL injection in PostgreSQL               pg_createsubscriber allows an attacker with               pg_create_subscription rights to execute arbitrary SQL as a               superuser. The attack takes effect when pg_createsubscriber next               runs. Versions before PostgreSQL 17 are unaffected.


              PostgreSQL libpq lo_* functions let server superuser overwrite               client stack memory. Use of inherently dangerous function               PQfn(..., result_is_int=0, ...) in PostgreSQL libpq lo_export(),               lo_read(), lo_lseek64(), and lo_tell64() functions allows the               server superuser to overwrite a client stack buffer with an               arbitrarily-large response. Like gets(), PQfn(...,               result_is_int=0, ...) stores arbitrary-length, server-determined               data into a buffer of unspecified size. Because both the               \lo_export command in psql and pg_dump call lo_read(), the               server superuser can overwrite pg_dump or psql stack memory.


              PostgreSQL discloses MD5-hashed passwords via covert timing               channel. Covert timing channel in comparison of MD5-hashed               password in PostgreSQL authentication allows an attacker to               recover user credentials sufficient to authenticate. This does               not affect scram-sha-256 passwords, the default in all supported               releases. However, current databases may have MD5-hashed               passwords originating in upgrades from PostgreSQL 13 or earlier.


              PostgreSQL SSL/GSS init causes denial of service, via               uncontrolled recursion. Uncontrolled recursion in PostgreSQL SSL               and GSS negotiation allows an attacker able to connect to a               PostgreSQL AF_UNIX socket to achieve sustained denial of               service. If SSL and GSS are both disabled, an attacker can do               the same via access to a PostgreSQL TCP socket.


              PostgreSQL pg_restore_attribute_stats accepts values that cause               query planning to read past end of stats array. Buffer over-read               in PostgreSQL function pg_restore_attribute_stats() accepts               array values of unmatched length, which causes query planning to               read past end of one array. This allows a table maintainer to               infer memory values past that array end. Versions before               PostgreSQL 18 are unaffected.


              PostgreSQL refint allows stack buffer overflow and SQL               injection. Stack buffer overflow in PostgreSQL module refint               allows an unprivileged database user to execute arbitrary code               as the operating system user running the database. A distinct               attack is possible if the application declares a user-controlled               column as a refint cascade primary key and facilitates               user-controlled updates to that column. In that case, a SQL               injection allows a primary key update value provider to execute               arbitrary SQL as the database user performing the primary key               update.


              PostgreSQL REFRESH PUBLICATION allows SQL injection via table               name. SQL injection in PostgreSQL logical replication ALTER               SUBSCRIPTION ... REFRESH PUBLICATION allows a subscriber table               creator to execute arbitrary SQL with the subscription's               publication-side credentials. The attack takes effect at the               next REFRESH PUBLICATION. Versions before PostgreSQL 16 are               unaffected.

    Multiple vulnerabilities have been discocvered in Wireshark, a network     protocol analyzer which could result in denial of service or the     execution of arbitrary code.

    For the oldstable distribution (bookworm), a subset of these problems     have been fixed in version 4.0.17-0+deb12u3.

    For the stable distribution (trixie), these problems have been fixed in     version 4.4.15-0+deb13u1.

    We recommend that you upgrade your wireshark packages.
