Vyper 安全漏洞

Vyper is the Pythonic smart contract language for EVM. A security vulnerability exists in Vyper 0.3.10 and prior versions, which stems from a security issue with the built-in sqrt parameter...

There is a large precision error in sqrt calculation of lp

Lines of code Vulnerability details Impact Compared with div, there is a larger precision error in calculating lp through sqrt, so there should be a way to check whether there are excess tokens left when adding liquidity. Proof of Concept function testCalcLpTokenSupplyDiff public uint256 memory...

SUSE CVE-2022-0778

The BNmodsqrt function, which computes a modular square root, contains a bug that can cause it to loop forever for non-prime moduli. Internally this function is used when parsing certificates that contain elliptic curve public keys in compressed form or explicit elliptic curve parameters with a...

CVE-2022-0778 - Infinite loop in BN_mod_sqrt() reachable when parsing certificates

Security Advisory ID: BSA-2022-1752 Component: OpenSSL Revision: 2.0 The BNmodsqrt function, which computes a modular square root, contains a bug that can cause it to loop forever for non-prime moduli. More information is at https://www.openssl.org/news/secadv/20220315.txt Affected Products Broca...

openssl: Infinite loop in BN_mod_sqrt() reachable when parsing certificates

A flaw was found in OpenSSL. It is possible to trigger an infinite loop by crafting a certificate that has invalid elliptic curve parameters. Since certificate parsing happens before verification of the certificate signature, any process that parses an externally supplied certificate may be subje...

Name of the Vulnerable Software and Affected Versions OpenSSL versions 1.0.2 through 1.0.2zc OpenSSL versions 1.1.1 through 1.1.1m OpenSSL versions 3.0.0 through 3.0.1 Description The BN mod sqrt function in OpenSSL contains a bug that can cause it to loop forever for non-prime moduli, leading to...

CVE-2017-9230

The Bitcoin Proof-of-Work algorithm does not consider a certain attack methodology related to 80-byte block headers with a variety of initial 64-byte chunks followed by the same 16-byte chunk, multiple candidate root values ending with the same 4 bytes, and calculations involving sqrt numbers. Th...
