Description SMASH SMASH 2024-05-02 10:36:26 UTC

After deserializing the quote info it was not checked whether the magic number in the attest is equal TPM2_GENERATED_VALUE. So a malicious attacker could generate arbitrary quote data which was not detected by Fapi_VerifyQuote. Now the number magic number is checked in verify quote and also
in the deserialization of TPM2_GENERATED. The check is also added to the Unmarshal function for TPMS_ATTEST.

Comment 2 Matthias Gerstner 2024-05-03 14:16:21 UTC

The FAPI library is not yet present in the following codestreams:

- SUSE:SLE-12-SP3:Update
- SUSE:SLE-12-SP5:Update
- SUSE:SLE-15:Update

I submitted updates for:

- SUSE:SLE-15-SP3:Update
- SUSE:SLE-15-SP4:Update
- SUSE:SLE-15-SP6:Update

The Factory package has been bumped to version 4.1 containing the fixes.

Once the Factory submission has been accepted, I will forward this package to
SUSE:ALP:Source:Standard:1.0, which is also affected.
