ONLY THE LAST DISPUTE IS CONSIDERED UNRESOLVED IN THE Distributor CONTRACT

Lines of code Vulnerability details Impact The Distributor.disputeTree function is used to freeze the Merkle tree update until the dispute is resolved. This is done by setting the disputer state variable to msg.sender. disputeTree is an external function which can be called by anyone by providing...

The merkle tree might be revoked again after being used to claim rewards.

Lines of code Vulnerability details Impact The merkle tree might be revoked again after being used to claim rewards. Proof of Concept The governor can revoke the merkle tree using revokeTree. function revokeTree external onlyGovernorOrGuardian if disputer != address0 revert UnresolvedDispute;...

Poor detection of disputed trees allows claiming tokens from a disputed tree

Lines of code Vulnerability details Targets Impact Users can claim rewards from a Merkle tree that's being disputed. This can potentially lead to loss of funds since a malicious trusted EOA can claim funds from a malicious tree while it's being disputed. Proof of Concept The...

SUSE CVE-2023-2861

A flaw was found in the 9p passthrough filesystem 9pfs implementation in QEMU. The 9pfs server did not prohibit opening special files on the host side, potentially allowing a malicious client to escape from the exported 9p tree by creating and opening a device file in the shared folder...

PT-2023-18008 · Google · Android Kernel

Name of the Vulnerable Software and Affected Versions: Android kernel Description: The issue is related to a possible out of bounds write in the load dt data function of storage.c due to a missing bounds check. This could lead to local escalation of privilege, requiring System execution privilege...

Improper Input Validation

@openzeppelin/contracts and @openzeppelin/contracts-upgradeable are vulnerable to Improper Input Validation. If a contract uses multiproofs for verification and the merkle tree processing includes a node with value 0 at depth 1, then the contract may be insecure. Balanced trees with three or fewe...

OpenZeppelin Contracts using MerkleProof multiproofs may allow proving arbitrary leaves for specific trees

Impact When the verifyMultiProof, verifyMultiProofCalldata, processMultiProof, or processMultiProofCalldata functions are in use, it is possible to construct merkle trees that allow forging a valid multiproof for an arbitrary set of leaves. A contract may be vulnerable if it uses multiproofs for...

PT-2023-5746 · Linux · Linux Kernel

Name of the Vulnerable Software and Affected Versions: Linux Kernel versions prior to 6.4 Description: The issue is related to a use-after-free flaw in the radix tree lookup function in the Linux Kernel's Radix tree node cache. This flaw may allow a local attacker to crash the system and lead to ...

CVE-2023-34459

OpenZeppelin Contracts is a library for smart contract development. Starting in version 4.7.0 and prior to version 4.9.2, when the verifyMultiProof, verifyMultiProofCalldata, procesprocessMultiProof, or processMultiProofCalldat functions are in use, it is possible to construct merkle trees that...

CVE-2023-34459

OpenZeppelin Contracts (versions 4.7.0–4.9.1) are affected by a multiproof forgery issue when using verifyMultiProof/verifyMultiProofCalldata/processMultiProof/processMultiProofCalldata. If the merkle tree includes a node with value 0 at depth 1 under the root, a adversarial or certain benign tre...
