GHSA-7VRM-3JC8-5WWM Incorrect Comparison in Vyper

Impact bytestrings can have dirty bytes in them, resulting in the word-for-word comparison to give incorrect results, e.g. vyper b1: Bytes32 = b"abcdef" b1 = sliceb1, 0, 1 b2: Bytes32 = b"abcdef" t: bool = b1 == b2 incorrectly evaluates to True even without dirty nonzero bytes, because there is n...

PYSEC-2022-196

Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine. In version 0.3.1 and prior, bytestrings can have dirty bytes in them, resulting in the word-for-word comparisons giving incorrect results. Even without dirty nonzero bytes, two bytestrings can compare to equal if one en...

Vyper 安全漏洞

Vyper is the Pythonic smart contract language for EVM. Vyper suffers from a security vulnerability that stems from the possibility of dirty bytes in the byte test ring in version 0.3.1 and earlier, causing word-by-word comparisons to give incorrect results. Even in the absence of dirty non-zero...

expat: Malformed 2- and 3-byte UTF-8 sequences can lead to arbitrary code execution

A flaw was found in expat. Passing malformed 2- and 3-byte UTF-8 sequences for example, from start tag names to the XML processing application on top of expat can lead to arbitrary code execution. This issue is dependent on how invalid UTF-8 is handled inside the XML processor...

Improper Verification of Cryptographic Signature in node-forge

Impact RSA PKCS1 v1.5 signature verification code does not check for tailing garbage bytes after decoding a DigestInfo ASN.1 structure. This can allow padding bytes to be removed and garbage data added to forge a signature when a low public exponent is being used. Patches The issue has been...
