TITLE

Red Hat Security Advisory 2022-5924-01

DESCRIPTION

When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches. curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using and trustingthe responses it got *before* the TLS handshake as if they were authenticated.Using this flaw, it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-through the TLS traffic from the legitimate server and trick curl into sending data back to the user thinking the attacker's injected data comes from the TLS-protected server. A STARTTLS protocol injection flaw via man-in-the-middle was found in curl prior to 7.79.0. Such multiple "pipelined" responses are cached by curl. Over POP3 and IMAP an attacker can inject fake response data. 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. Dockerfiles and scripts should be amended either to refer to this new image specifically, or to the latest image generally. Bugs fixed (https://bugzilla.redhat.com/): 2107342 - CVE-2022-30631 golang: compress/gzip: stack exhaustion in Reader.Read 5. Description: Red Hat 3scale API Management delivers centralized API management features through a distributed, cloud-hosted layer. It includes built-in features to help in building a more successful API program, including access control, rate limits, payment gateway integration, and developer experience tools. This advisory is intended to use with Container Images, for Red Hat 3scale API Management 2.11.1. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied.
