Synopsis
The remote Red Hat host is missing one or more security updates.Description
The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2023:5209 advisory.- Insufficient granularity of access control in out-of-band management in some Intel(R) Atom and Intel Xeon Scalable Processors may allow a privileged user to potentially enable escalation of privilege via adjacent network access. (CVE-2022-21216)
- Incorrect default permissions in some memory controller configurations for some Intel(R) Xeon(R) Processors when using Intel(R) Software Guard Extensions which may allow a privileged user to potentially enable escalation of privilege via local access. (CVE-2022-33196)
- There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName.
X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME incorrectly specified the type of the x400Address field as ASN1_TYPE. This field is subsequently interpreted by the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an ASN1_STRING. When CRL checking is enabled (i.e. the application sets the X509_V_FLAG_CRL_CHECK flag), this vulnerability may allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory contents or enact a denial of service. In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network. (CVE-2023-0286)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
