GHSA-9RCW-C2F9-2J55 OpenZeppelin Contracts Bytes's lastIndexOf function with position argument performs out-of-bound memory access on empty buffers

Impact The lastIndexOfbytes,byte,uint256 function of the Bytes.sol library may access uninitialized memory when the following two conditions hold: 1 the provided buffer length is empty i.e. buffer.length == 0 and position is not 2256 - 1 i.e. pos != typeuint256.max. The pos argument could be used...

CVE-2024-45304

Cairo-Contracts are OpenZeppelin Contracts written in Cairo for Starknet, a decentralized ZK Rollup. This vulnerability can lead to unauthorized ownership transfer, contrary to the original owner's intention of leaving the contract without an owner. It introduces a security risk where an unintend...

CVE-2024-27094

OpenZeppelin Contracts is a library for secure smart contract development. The Base64.encode function encodes a bytes input by iterating over it in chunks of 3 bytes. When this input is not a multiple of 3, the last iteration may read parts of the memory that are beyond the input buffer. The...
