Ubuntu 16.04 LTS / 18.04 LTS : PostgreSQL vulnerabilities (USN-4090-1)

high Nessus Plugin ID 127806

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4090-1 advisory.

 Tom Lane discovered that PostgreSQL did not properly restrict functions declared as SECURITY DEFINER. An attacker could use this to execute arbitrary SQL with the permissions of the function owner.
 (CVE-2019-10208)

 Andreas Seltenreich discovered that PostgreSQL did not properly handle user-defined hash equality operators. An attacker could use this to expose sensitive information (arbitrary PostgreSQL server memory). This issue only affected Ubuntu 19.04. (CVE-2019-10209)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
