CVE-2021-22925

TITLE

Red Hat Security Advisory 2021-5137-03

DESCRIPTION

curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS`in libcurl. This rarely used option is used to send variable=content pairs toTELNET servers.Due to flaw in the option parser for sending `NEW_ENV` variables, libcurlcould be made to pass on uninitialized data from a stack based buffer to theserver. Therefore potentially revealing sensitive internal information to theserver using a clear-text network protocol.This could happen because curl did not call and use sscanf() correctly whenparsing the string provided by the application. A has been found in curl. The fix for CVE-2021-22898 doesn't remedy the vulnerability. The highest threat from this vulnerability is to confidentiality. 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. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: curl security and bug fix update Advisory ID: RHSA-2021:4511-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:4511 Issue date: 2021-11-09 CVE Names: CVE-2021-22876 CVE-2021-22898 CVE-2021-22925 ==================================================================== 1.

Description: Red Hat OpenShift Container Storage is software-defined storage integrated with and optimized for the Red Hat OpenShift Container Platform. 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.
