DescriptionNVD

In GnuPG before 2.5.17, a stack-based buffer overflow exists in tpm2daemon during handling of the PKDECRYPT command for TPM-backed RSA and ECC keys.

AnalysisAI

Stack-based buffer overflow in GnuPG's tpm2daemon component allows local attackers to achieve full system compromise through specially crafted PKDECRYPT commands targeting TPM-backed RSA and ECC keys. Public exploit code exists for this vulnerability, which affects GnuPG versions before 2.5.17 and impacts users of GnuPG, Gpg4win, and Stack Overflow integrations. …
