Handling 'unknown'-type values from string literals without type designation can disclose bytes, potentially revealing notable and confidential information. This issue exists due to excessive data output in aggregate function calls, enabling remote users to read some portion of system memory. ## Affected - `postgresql >= 11.0, < 11.22` - `postgresql >= 12.0, < 12.17` - `postgresql >= 13.0, < 13.13` - `postgresql >= 14.0, < 14.10` - `postgresql >= 15.0, < 15.5` - `postgresql = 16.0` - `codeready_linux_builder_eus = 9.2` - `codeready_linux_builder_eus_for_power_little_endian_eus = 9.0_ppc64le` - `codeready_linux_builder_eus_for_power_little_endian_eus = 9.2_ppc64le` - `codeready_linux_builder_for_arm64_eus = 8.6_aarch64` - `codeready_linux_builder_for_arm64_eus = 9.0_aarch64` - `codeready_linux_builder_for_arm64_eus = 9.2_aarch64` - `codeready_linux_builder_for_ibm_z_systems_eus = 9.0_s390x` - `codeready_linux_builder_for_ibm_z_systems_eus = 9.2_s390x` - `codeready_linux_builder_for_power_little_endian_eus = 9.0_ppc64le` - `codeready_linux_builder_for_power_little_endian_eus = 9.2_ppc64le` - `software_collections = 1.0` - `enterprise_linux = 8.0` - `enterprise_linux = 9.0` - `enterprise_linux_eus = 8.6` - `enterprise_linux_eus = 8.8` - `enterprise_linux_eus = 9.0` - `enterprise_linux_eus = 9.2` - `enterprise_linux_for_arm_64 = 8.0` - `enterprise_linux_for_arm_64 = 8.8_aarch64` - `enterprise_linux_for_ibm_z_systems = 8.0_s390x` - `enterprise_linux_for_ibm_z_systems_eus = 8.6_s390x` - `enterprise_linux_for_ibm_z_systems_eus = 8.8_s390x` - `enterprise_linux_for_ibm_z_systems_eus = 9.0_s390x` - `enterprise_linux_for_ibm_z_systems_eus = 9.2_s390x` - `enterprise_linux_for_power_little_endian = 8.0_ppc64le` - `enterprise_linux_for_power_little_endian_eus = 8.6_ppc64le` - `enterprise_linux_for_power_little_endian_eus = 8.8_ppc64le` - `enterprise_linux_for_power_little_endian_eus = 9.0_ppc64le` - `enterprise_linux_for_power_little_endian_eus = 9.2_ppc64le` - `enterprise_linux_server_aus = 8.2` - `enterprise_linux_server_aus = 8.4` - `enterprise_linux_server_aus = 8.6` - `enterprise_linux_server_aus = 9.2` - `enterprise_linux_server_tus = 8.2` - `enterprise_linux_server_tus = 8.4` - `enterprise_linux_server_tus = 8.6` ## Remediation Upgrade past the affected range: - `postgresql 15.5`
