CVE-2022-0778

CVE-2022-0778 该漏洞会在解析椭圆曲线密钥时触发 OpenSSL 中 BNmodsqrt 函数的无限循环。这意味着一个恶意构造的 X.509 证书可以对任何未修补的服务器发起 DoS 攻击。 漏洞的核心在于解析以压缩格式表示点的 EC 密钥过程中：在解析此类密钥时，OpenSSL 会尝试扩展压缩点，试图计算曲线定义素数 p 的模平方根。然而，p 的素性未在任何地方检查，即使在需要它的 BNmodsqrt 中也不例外；因此，由于 p 不是预期的素数，实现中的一个错误会导致无限循环。 中文版说明可以见我的博客OpenSSL CVE-2022-0778漏洞问题复现与非法证书构造 致...

Gitea SSH Key Parser Denial of Service

Gitea's SSH key ingestion endpoint accepts keys in RFC 4716 SSH2 format and normalises them before storage. The normalisation function contains an ON² string concatenation loop with no input size limit, meaning a single malicious key submission can force the server to perform an amount of work th...

ConnectBot SSH Client Library: Excessive allocation and integer overflow in DER private-key parsing

Summary The DER parser used for application-supplied private keys did not safely validate encoded length values before converting them to Int values or allocating arrays. A malformed private-key file could encode a length that overflowed or wrapped around, or request an allocation much larger tha...
