GitHub Vulnerability Alerts

CVE-2024-27094

Impact

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.

Although the encode function pads the output for these cases, up to 4 bits of data are kept between the encoding and padding, corrupting the output if these bits were dirty (i.e. memory after the input is not 0). These conditions are more frequent in the following scenarios:

• A bytes memory struct is allocated just after the input and the first bytes of it are non-zero.
• The memory pointer is set to a non-empty memory location before allocating the input.

Developers should evaluate whether the extra bits can be maliciously manipulated by an attacker.

Patches

Upgrade to 5.0.2 or 4.9.6.

Release Notes

OpenZeppelin/openzeppelin-contracts (@​openzeppelin/contracts)

v4.9.6

Compare Source

• Base64: Fix issue where dirty memory located just after the input buffer is affecting the result. (#​4929)

v4.9.5

Compare Source

• Multicall: Make aware of non-canonical context (i.e. msg.sender is not _msgSender()), allowing compatibility with ERC2771Context. Patch duplicated Address.functionDelegateCall in v4.9.4 (removed).

v4.9.4

Compare Source

• ERC2771Context and Context: Introduce a _contextPrefixLength() getter, used to trim extra information appended to msg.data.
