Synopsis
The remote Red Hat CoreOS host is missing one or more security updates for Red Hat OpenShift Enterprise.Description
The remote Red Hat Enterprise Linux CoreOS 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:3910 advisory.- An attacker can cause excessive memory growth in a Go server accepting HTTP/2 requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection. (CVE-2022-41717)
- Not all valid JavaScript whitespace characters are considered to be whitespace. Templates containing whitespace characters outside of the character set \t\n\f\r\u0020\u2028\u2029 in JavaScript contexts that also contain actions may not be properly sanitized during execution. (CVE-2023-24540)
- A compliance problem was found in the Red Hat OpenShift Container Platform. Red Hat discovered that, when FIPS mode was enabled, not all of the cryptographic modules in use were FIPS-validated. (CVE-2023-3089)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
