TITLE

Red Hat Security Advisory 2021-5191-02

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: 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.

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. 8) - aarch64, ppc64le, s390x, x86_64 3. Description: The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP. This version of the OpenShift Serverless Operator is supported on Red Hat OpenShift Container Platform versions 4.6, 4.7, 4.8 and 4.9, and includes security and bug fixes and enhancements.
