TITLE

Haxx libcurl Information disclosure vulnerability

DESCRIPTION

curl 7.1.1 to and including 7.75.0 is vulnerable to an "Exposure of Private Personal Information to an Unauthorized Actor" by leaking credentials in the HTTP Referer: header. libcurl does not strip off user credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second HTTP request. This could lead to exposure of the credentials to the server to which requests were redirected. (CVE-2021-22876) A vulnerability was found in curl where a flaw in the option parser for sending NEW_ENV variables libcurl can pass uninitialized data from a stack-based buffer to the server. This issue leads to potentially revealing sensitive internal information to the server using a clear-text network protocol. The highest threat from this vulnerability is to confidentiality. (CVE-2021-22898). -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-4881-1 security@debian.org https://www.debian.org/security/ Alessandro Ghedini March 30, 2021 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : curl CVE ID : CVE-2020-8169 CVE-2020-8177 CVE-2020-8231 CVE-2020-8284 CVE-2020-8285 CVE-2020-8286 CVE-2021-22876 CVE-2021-22890 Debian Bug : 965280 965281 968831 977161 977162 977163 Multiple vulnerabilities were discovered in cURL, an URL transfer library: CVE-2020-8169 Marek Szlagor reported that libcurl could be tricked into prepending a part of the password to the host name before it resolves it, potentially leaking the partial password over the network and to the DNS server(s). CVE-2020-8177 sn reported that curl could be tricked by a malicious server into overwriting a local file when using th -J (--remote-header-name) and -i (--include) options in the same command line. CVE-2020-8231 Marc Aldorasi reported that libcurl might use the wrong connection when an application using libcurl's multi API sets the option CURLOPT_CONNECT_ONLY, which could lead to information leaks. CVE-2020-8284 Varnavas Papaioannou reported that a malicious server could use the PASV response to trick curl into connecting back to an arbitrary IP address and port, potentially making curl extract information about services that are otherwise private and not disclosed. CVE-2020-8285 xnynx reported that libcurl could run out of stack space when using tha FTP wildcard matching functionality (CURLOPT_CHUNK_BGN_FUNCTION). CVE-2020-8286 It was reported that libcurl didn't verify that an OCSP response actually matches the certificate it is intended to. CVE-2021-22890 Mingtao Yang reported that, when using an HTTPS proxy and TLS 1.3, libcurl could confuse session tickets arriving from the HTTPS proxy as if they arrived from the remote server instead. This could allow an HTTPS proxy to trick libcurl into using the wrong session ticket for the host and thereby circumvent the server TLS certificate check. For the stable distribution (buster), these problems have been fixed in version 7.64.0-4+deb10u2. We recommend that you upgrade your curl packages.

Description: Gatekeeper Operator v0.2 Gatekeeper is an open source project that applies the OPA Constraint Framework to enforce policies on your Kubernetes clusters. This advisory contains the container images for Gatekeeper that include security updates, and container upgrades. For support options for any other use, see the Gatekeeper open source project website at: https://open-policy-agent.github.io/gatekeeper/website/docs/howto/. Security updates: * golang.org/x/crypto: empty plaintext packet causes panic (CVE-2021-43565) * golang: crypto/elliptic IsOnCurve returns true for invalid field elements (CVE-2022-23806) 3. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. The requirements to apply the upgraded images are different whether or not you used the operator. Complete the following steps, depending on your installation: - - Upgrade gatekeeper operator: The gatekeeper operator that is installed by the gatekeeper operator policy has `installPlanApproval` set to `Automatic`. This setting means the operator will be upgraded automatically when there is a new version of the operator. No further action is required for upgrade. If you changed the setting for `installPlanApproval` to `manual`, then you must view each cluster to manually approve the upgrade to the operator. - - Upgrade gatekeeper without the operator: The gatekeeper version is specified as part of the Gatekeeper CR in the gatekeeper operator policy. To upgrade the gatekeeper version: a) Determine the latest version of gatekeeper by visiting: https://catalog.redhat.com/software/containers/rhacm2/gatekeeper-rhel8/5fadb4a18d9a79d2f438a5d9. b) Click the tag dropdown, and find the latest static tag. An example tag is 'v3.3.0-1'. c) Edit the gatekeeper operator policy and update the image tag to use the latest static tag. For example, you might change this line to image: 'registry.redhat.io/rhacm2/gatekeeper-rhel8:v3.3.0-1'. Bugs fixed (https://bugzilla.redhat.com/): 2030787 - CVE-2021-43565 golang.org/x/crypto: empty plaintext packet causes panic 2053429 - CVE-2022-23806 golang: crypto/elliptic IsOnCurve returns true for invalid field elements 5.
