An out-of-bounds write vulnerability exists in TPM2.0's Module Library allowing writing of a 2-byte data past the end of TPM2.0 command in the CryptParameterDecryption routine. An attacker who can successfully exploit this vulnerability can lead to denial of service (crashing the TPM chip/process or rendering it unusable) and/or arbitrary code execution in the TPM context.
An out-of-bounds read vulnerability exists in TPM2.0's Module Library allowing a 2-byte read past the end of a TPM2.0 command in the CryptParameterDecryption routine. An attacker who can successfully exploit this vulnerability can read or access sensitive data stored in the TPM.
A remote code execution vulnerability exists in the way that Microsoft Graphics Components handle objects in memory. An attacker who successfully exploited the vulnerability could execute arbitrary code on a target system.
To exploit the vulnerability, a user would have to open a specially crafted file.
The security update addresses the vulnerability by correcting how Microsoft Graphics Components handle objects in memory.
