Red Hat Security Advisory: openssl-container security update

Notes

Topic
An update for openssl-container is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. [Updated 03 November 2022] This erratum was previously incorrectly marked as having a security impact of Critical, and it failed to mention all issues addressed in this update. The security impact of this erratum has been changed to Important, and CVE-2022-3786 was added to the CVE list. No changes have been made to the container image content.
Details
The ubi9/openssl image provides provides an openssl command-line tool for using the various functions of the OpenSSL crypto library. Using the OpenSSL tool, you can generate private keys, create certificate signing requests (CSRs), and display certificate information. This updates the ubi9/openssl image in the Red Hat Container Registry. To pull this container image, run one of the following commands: podman pull registry.redhat.io/rhel9/openssl (authenticated) podman pull registry.access.redhat.com/ubi9/openssl (unauthenticated) Security Fix(es): * OpenSSL: X.509 Email Address Buffer Overflow (CVE-2022-3602) * OpenSSL: X.509 Email Address Variable Length Buffer Overflow (CVE-2022-3786) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

A client connecting to a malicious server is also believed to be vulnerable in the same manner. Only OpenSSL versions 3.0.0 to 3.0.6 are vulnerable to this attack.\nThe OpenSSL binaries in Red Hat Enterprise Linux 9 are compiled with Stack Smashing Protection. Also during the build process, the compiler rearranges the variables in a way that the buffer overflow is only able to overwrite the stack canaries, limiting the maximum impact of this flaw to denial of service. Remote code execution may not be possible in such cases.\n\nRed Hat OpenStack Platform 17 does not ship OpenSSL and is not directly affected by the flaw. However, container images which product ship are of RHEL 9 which were affected. RHOSP have fixed this by respining container images through the following errata: https://access.redhat.com/errata/RHBA-2022:7429",
