**Name of the Vulnerable Software and Affected Versions** Mbed TLS versions prior to 2.28.2 Mbed TLS versions 3.x prior to 3.3.0 **Description** An issue allows an adversary with access to precise enough information about memory accesses to recover an RSA private key after observing the victim performing a single private-key operation. This is possible if the window size used for the exponentiation is 3 or smaller, specifically when `MBEDTLS MPI WINDOW SIZE` is set to 3 or smaller. The attack typically involves an untrusted operating system attacking a secure enclave. **Recommendations** For Mbed TLS versions prior to 2.28.2, update to version 2.28.2 or later. For Mbed TLS versions 3.x prior to 3.3.0, update to version 3.3.0 or later. As a temporary workaround, consider increasing the `MBEDTLS MPI WINDOW SIZE` to a value larger than 3 to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** Mbed TLS versions prior to 2.28.2 Mbed TLS versions 3.x prior to 3.3.0 **Description** A potential heap-based buffer overflow and heap-based buffer over-read exists in DTLS if `MBEDTLS SSL DTLS CONNECTION ID` is enabled and `MBEDTLS SSL CID IN LEN MAX` is greater than 2 times `MBEDTLS SSL CID OUT LEN MAX`. This issue can be exploited by a remote attacker to overwrite data in the buffer memory and potentially recover a closed RSA key. **Recommendations** For Mbed TLS versions prior to 2.28.2, update to version 2.28.2 or later. For Mbed TLS versions 3.x prior to 3.3.0, update to version 3.3.0 or later. As a temporary workaround, consider disabling the `MBEDTLS SSL DTLS CONNECTION ID` feature until a patch is available. Restrict access to DTLS connections where `MBEDTLS SSL CID IN LEN MAX` is greater than 2 times `MBEDTLS SSL CID OUT LEN MAX` to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** Intel Processors with Intel Processor Graphics (affected versions not specified) **Description** The issue is related to insufficient control flow in certain data structures for Intel Processors with Intel Processor Graphics, which may allow an unauthenticated user to potentially enable information disclosure via local access. This could allow an attacker to disclose protected information. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Microsoft Windows versions prior to Windows XP SP4, Windows Server 2003 SP3, Windows Vista SP3, Windows Server 2008 SP3, and Windows 7 SP1 **Description** An elevation of privilege issue exists due to the improper interaction of drivers with the Windows kernel. This allows local users to gain privileges and bypass the User Account Control (UAC) feature via a crafted REG BINARY value for a SystemDefaultEUDCFont registry key. An attacker who successfully exploited this issue could run arbitrary code in kernel mode and take complete control of an affected system, enabling them to install programs, view, change, or delete data, or create new accounts with full administrative rights. **Recommendations** For Microsoft Windows XP SP2 and SP3, update to Windows XP SP4 to resolve the issue. For Windows Server 2003 SP2, update to Windows Server 2003 SP3 to resolve the issue. For Windows Vista SP1 and SP2, update to Windows Vista SP3 to resolve the issue. For Windows Server 2008 Gold, SP2, and R2, update to Windows Server 2008 SP3 to resolve the issue. For Windows 7, update to Windows 7 SP1 to resolve the issue. As a temporary workaround, consider restricting access to the SystemDefaultEUDCFont registry key to minimize the risk of exploitation.
