Information Disclosure

github.com/google/go-tpm is vulnerable to information disclosure. An attacker is able to discover the encUsageAuth and encMigrationAuth values and calculateusageAuth ^ encMigrationAuth since the migrationAuth can be guessed for all keys created with CreateWrapKey, and subsequently discover the au...

CVE-2020-8918

An improperly initialized 'migrationAuth' value in Google's go-tpm TPM1.2 library versions prior to 0.3.0 can lead an eavesdropping attacker to discover the auth value for a key created with CreateWrapKey. An attacker listening in on the channel can collect both 'encUsageAuth' and...

CVE-2020-8918 TPM 1.2 key authorization values are vulnerable to a TPM transport eavesdropper

An improperly initialized 'migrationAuth' value in Google's go-tpm TPM1.2 library versions prior to 0.3.0 can lead an eavesdropping attacker to discover the auth value for a key created with CreateWrapKey. An attacker listening in on the channel can collect both 'encUsageAuth' and...

CVE-2020-8918

The CVE-2020-8918 issue affects Google's go-tpm TPM1.2 library prior to 0.3.0, where a bug initializes migrationAuth, allowing a local attacker eavesdropping on TPM1.2 transport to compute usageAuth for keys created with CreateWrapKey by XOR’ing encUsageAuth and encMigrationAuth. TPM2.0 is not af...

Microsoft Guidance for Addressing Security Feature Bypass in GRUB

Executive Summary Microsoft is aware of a vulnerability in the GRand Unified Boot Loader GRUB, commonly used by Linux. This vulnerability, known as “There’s a Hole in the Boot”, could allow for Secure Boot bypass. To exploit this vulnerability, an attacker would need to have administrative...

Information Disclosure

kernel is vulnerable to information disclosure. The vulnerability exists through a flaw in the way memory containing security-related data was handled in tpmread could allow a local, unprivileged user to read the results of a previously run TPM command...

New Crypto in Go 1.14

Go 1.14 is out and with it come a few nice updates to crypto/tls! Will this certificate work? Certificate selection in TLS1 is a mess. I was going to try and describe it here to make the point, but I kept getting it wrong and it was even too messy for something just meant to make the point that i...
