TITLE

Red Hat Security Advisory 2022-5924-01

DESCRIPTION

A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network. Description: Service Telemetry Framework (STF) provides automated collection of measurements and data from remote clients, such as Red Hat OpenStack Platform or third-party nodes. STF then transmits the information to a centralized, receiving Red Hat OpenShift Container Platform (OCP) deployment for storage, retrieval, and monitoring. Solution: The Service Telemetry Framework container image provided by this update can be downloaded from the Red Hat Container Registry at registry.access.redhat.com. Installation instructions for your platform are available at Red Hat Container Catalog (see References). Dockerfiles and scripts should be amended either to refer to this new image specifically, or to the latest image generally.

One of the fixes introduced a regression on Ubuntu 18.04 LTS. This update fixes the problem. We apologize for the inconvenience. Original advisory details: It was discovered that curl incorrect handled memory when sending data to an MQTT server. A remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2021-22945) Patrick Monnerat discovered that curl incorrectly handled upgrades to TLS. (CVE-2021-22946) Patrick Monnerat discovered that curl incorrectly handled responses received before STARTTLS. A remote attacker could possibly use this issue to inject responses and intercept communications. (CVE-2021-22947) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: curl 7.58.0-2ubuntu3.16 libcurl3-gnutls 7.58.0-2ubuntu3.16 libcurl3-nss 7.58.0-2ubuntu3.16 libcurl4 7.58.0-2ubuntu3.16 In general, a standard system update will make all the necessary changes.
