medium Tenable Cloud Security Plugin ID 406517

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - 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. (CVE-2021-3393)

 - A flaw was found in PostgreSQL in versions before 13.2. This flaw allows a user with SELECT privilege on
 one column to craft a special query that returns all columns of the table. The highest threat from this
 vulnerability is to confidentiality. (CVE-2021-20229)
