SCA: security update for @openzeppelin/contracts, @openzeppelin/contracts-upgradeable (GHSA-9rcw-c2f9-2j55)

medium Tenable Self-Hosted Container Security Plugin ID 428438

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - OpenZeppelin Contracts is a library for secure smart contract development. Starting in version 5.2.0 and
 prior to version 5.4.0, the `lastIndexOf(bytes,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 `2**256 - 1` (i.e. `pos != type(uint256).max`). The `pos`
 argument could be used to access arbitrary data outside of the buffer bounds. This could lead to the
 operation running out of gas, or returning an invalid index (outside of the empty buffer). Processing this
 invalid result for accessing the `buffer` would cause a revert under normal conditions. When triggered,
 the function reads memory at offset `buffer + 0x20 + pos`. If memory at that location (outside the
 `buffer`) matches the search pattern, the function would return an out of bound index instead of the
 expected `type(uint256).max`. This creates unexpected behavior where callers receive a valid-looking index
 pointing outside buffer bounds. Subsequent memory accesses that don't check bounds and use the returned
 index must carefully review the potential impact depending on their setup. Code relying on this function
 returning `type(uint256).max` for empty buffers or using the returned index without bounds checking could
 exhibit undefined behavior. Users should upgrade to version 5.4.0 to receive a patch. (CVE-2025-54070)
