How to fix?

Upgrade SLES:15.2 postgresql12-plperl to version 12.6-8.16.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql12-plperl package and not the postgresql12-plperl package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

An information leak was discovered in postgresql in versions before 13.2, before 12.6 and before 11.11. A user having UPDATE permission but not SELECT permission to a particular column could craft queries which, under some circumstances, might disclose values from that column in error messages. An attacker could use this flaw to obtain information stored in a column they are allowed to write but not read.
