Vulnerabilidades

A BIOS bug in firmware for a particular PC model leaves the Platform authorization value empty. This can be used to permanently brick the TPM in multiple ways, as well as to non-permanently DoS the system.

NetworkPkg/IScsiDxe has remotely exploitable buffer overflows.

Example EDK2 encrypted private key in the IpSecDxe.efi present potential security risks.

A heap overflow in LzmaUefiDecompressGetInfo function in EDK II.

An unlimited recursion in DxeCore in EDK II.

Null pointer dereference in Tianocore EDK2 may allow an authenticated user to potentially enable escalation of privilege via local access.

Logic issue EDK II may allow an unauthenticated user to potentially enable denial of service via adjacent access.

Use after free vulnerability in EDK II may allow an authenticated user to potentially enable escalation of privilege, information disclosure and/or denial of service via adjacent access.

Logic issue in DxeImageVerificationHandler() for EDK II may allow an authenticated user to potentially enable escalation of privilege via local access.

Integer truncation in EDK II may allow an authenticated user to potentially enable escalation of privilege via local access.

Integer overflow in DxeImageVerificationHandler() EDK II may allow an authenticated user to potentially enable denial of service via local access.

Uncontrolled resource consumption in EDK II may allow an unauthenticated user to potentially enable denial of service via network access.

Improper authentication in EDK II may allow a privileged user to potentially enable information disclosure via network access.

Buffer overflow in the Reclaim function in Tianocore EDK2 before SVN 16280 allows physically proximate attackers to gain privileges via a long variable name.

Multiple integer overflows in the Pre-EFI Initialization (PEI) boot phase in the Capsule Update feature in the UEFI implementation in EDK2 allow physically proximate attackers to bypass intended access restrictions by providing crafted data that is not properly handled during the coalescing phase.

Integer overflow in the Drive Execution Environment (DXE) phase in the Capsule Update feature in the UEFI implementation in EDK2 allows physically proximate attackers to bypass intended access restrictions via crafted data.

Bounds checking in Tianocompress before November 7, 2017 may allow an authenticated user to potentially enable an escalation of privilege via local access.
