Ubuntu 20.04 LTS / 22.04 LTS : PostgreSQL vulnerability (USN-5906-1)

low Nessus Plugin ID 172050

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5906-1 advisory.

 - PostgreSQL Project reports: A modified, unauthenticated server can send an unterminated string during the establishment of Kerberos transport encryption. When a libpq client application has a Kerberos credential cache and doesn't explicitly disable option gssencmode, a server can cause libpq to over-read and report an error message containing uninitialized bytes from and following its receive buffer. If libpq's caller somehow makes that message accessible to the attacker, this achieves a disclosure of the over-read bytes. We have not confirmed or ruled out viability of attacks that arrange for a crash or for presence of notable, confidential information in disclosed bytes. (CVE-2022-41862)

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

Solution

Update the affected packages.
