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). Bugs fixed (https://bugzilla.redhat.com/): 2030932 - CVE-2021-44228 log4j-core: Remote code execution in Log4j 2.x when logs contain an attacker-controlled string value 5. 8) - aarch64, ppc64le, s390x, x86_64 3.

Software Description: - curl: HTTP, HTTPS, and FTP client and client libraries Details: Viktor Szakats discovered that curl did not strip off user credentials from referrer header fields. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 ESM: curl 7.35.0-1ubuntu2.20+esm7 libcurl3 7.35.0-1ubuntu2.20+esm7 libcurl3-gnutls 7.35.0-1ubuntu2.20+esm7 libcurl3-nss 7.35.0-1ubuntu2.20+esm7 In general, a standard system update will make all the necessary changes. Red Hat OpenShift Container Storage is highly scalable, production-grade persistent storage for stateful applications running in the Red Hat OpenShift Container Platform. In addition to persistent storage, Red Hat OpenShift Container Storage provides a multicloud data management service with an S3 compatible API. Bug Fix(es): * Previously, when the namespace store target was deleted, no alert was sent to the namespace bucket because of an issue in calculating the namespace bucket health. With this update, the issue in calculating the namespace bucket health is fixed and alerts are triggered as expected. (BZ#1993873) * Previously, the Multicloud Object Gateway (MCG) components performed slowly and there was a lot of pressure on the MCG components due to non-optimized database queries. With this update the non-optimized database queries are fixed which reduces the compute resources and time taken for queries. Bugs fixed (https://bugzilla.redhat.com/): 1993873 - [4.8.z clone] Alert NooBaaNamespaceBucketErrorState is not triggered when namespacestore's target bucket is deleted 2006958 - CVE-2020-26301 nodejs-ssh2: Command injection by calling vulnerable method with untrusted input 5
