Name of the Vulnerable Software and Affected Versions: Azure Virtual Machines (affected versions not specified) Description: Improper access control in Azure Virtual Machines allows an authorized attacker to perform spoofing locally. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

A remote attacker can recover plaintext because a certain Lucky 13 countermeasure doesn't properly consider the case of a hardware accelerator. This issue is related to the implementation of TLS and SSL protocols in Mbed TLS, allowing an attacker to access confidential data.

The issue is related to a side channel in modular exponentiation, which could disclose an RSA private key used in a secure enclave. This is due to a dependency of the instruction timing on the instruction data, allowing a remote attacker to access confidential data.

A side channel issue allows the recovery of an ECC private key. This is related to functions such as `mbedtls ecp check pub priv`, `mbedtls pk parse key`, `mbedtls pk parse keyfile`, `mbedtls ecp mul`, and `mbedtls ecp mul restartable`. The issue can be exploited by a remote attacker to gain access to confidential data.
