VMware released a security advisory to address multiple vulnerabilities in ESXi, Workstation, Fusion, and Cloud Foundation. A cyber threat actor could exploit one of these vulnerabilities to take control of an affected system. CISA encourages users and administrators to review the following VMware security advisory and apply the necessary updates: VMSA-2024-0006

CISA has added two new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. CVE-2024-23225 Apple iOS and iPadOS Memory Corruption Vulnerability CVE-2024-23296 Apple iOS and iPadOS Memory Corruption Vulnerability These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information. Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.
