Descriptions
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 write vulnerability was found in the TPM 2.0's Module Library, which allows the writing of 2-byte data after the end of the TPM command. This flaw may lead to a denial of service or arbitrary code execution within the libtpms scope.
Francisco Falcon discovered that Libtpms did not properly manage memory when performing certain cryptographic operations. An attacker could possibly use this issue to cause a denial of service, or possibly execute arbitrary code. It was discovered that Libtpms did not properly manage memory when handling certain commands. An attacker could possibly use this issue to cause a denial of service.
