The remote Ubuntu 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5933-1 advisory.
An out-of-bounds write vulnerability exists in TPM2.0βs 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. (CVE-2023-1017)
An out-of-bounds read vulnerability exists in TPM2.0βs 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. (CVE-2023-1018)
Note that Nessus has not tested for these issues but has instead relied only on the applicationβs self-reported version number.
