Multiple security issues have been discovered in the PostgreSQL database system, which could result in the execution of arbitrary code or disclosure of memory content.

This update for postgresql12 fixes the following issues :

Upgrade to version 12.7 :

CVE-2021-32027: Fixed integer overflows in array subscripting calculations (bsc#1185924).

CVE-2021-32028: Fixed mishandling of junk columns in INSERT ... ON CONFLICT ... UPDATE target lists (bsc#1185925).

CVE-2021-32029: Fixed possibly-incorrect computation of UPDATE ...
RETURNING 'pg_psql_temporary_savepoint' does not exist (bsc#1185926).

CVE-2021-3393: Fixed information leakage in constraint-violation error messages (bsc#1182040).

Don't use %_stop_on_removal, because it was meant to be private and got removed from openSUSE. %_restart_on_update is also private, but still supported and needed for now (bsc#1183168).

Re-enable build of the llvmjit subpackage on SLE, but it will only be delivered on PackageHub for now (bsc#1183118).

Disable icu for PostgreSQL 10 (and older) on TW (bsc#1179945).

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2021:0043 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2021-32027:
    A flaw was found in postgresql in versions before 13.3, before 12.7, before 11.12, before 10.17 and before     9.6.22. While modifying certain SQL array values, missing bounds checks let authenticated database users     write arbitrary bytes to a wide area of server memory. The highest threat from this vulnerability is to     data confidentiality and integrity as well as system availability.

    CVE-2021-32028:
    ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when     announcing a new security problem. When the candidate has been publicized, the details for this candidate     will be provided.

    CVE-2021-32029:

    (CVE-2021-32027)

    A flaw was found in postgresql. Using an INSERT ... ON CONFLICT ... DO UPDATE command on a purpose-crafted     table, an authenticated database user could read arbitrary bytes of server memory. The highest threat from     this vulnerability is to data confidentiality. (CVE-2021-32028)
