Incorrect hash in sha2

The v0.9.7 release of the sha2 crate introduced a new AVX2-accelerated backend which was automatically enabled for all x86/x8664 CPUs where AVX2 support was autodetected at runtime. This backend was buggy and would miscompute results for long messages i.e. messages spanning multiple SHA blocks. T...

GO-2021-0160 Incorrect calculation affecting RSA computations in math/big

Int.Exp Montgomery mishandled carry propagation and produced an incorrect output, which makes it easier for attackers to obtain private RSA keys via unspecified vectors. This issue can affect RSA computations in crypto/rsa, which is used by crypto/tls. TLS servers on 32-bit systems could plausibl...

Incentivizer rewards are unclear and can be more than allotted?

Handle cmichel Vulnerability details Note that the Incentivizer.create allocates programInfo.amount.sum tokens to be rewarded. It's unclear how the rewards that are actually paid out see Program.unsettled over the duration relate to this value. The ProgramInfo.amountPerShare returns the...

_getFirstSample returns wrong sample if count < sampleMemory

Inaccurate fees computation

Handle cmichel Vulnerability details The MixinTransfer.shareKey function wants to compute a fee such that time + fee time == timeRemaining timePlusFee: uint fee = getTransferFeekeyOwner, timeShared; uint timePlusFee = timeShared + fee; However, if the time remaining is less than the computed fee...

OverlayV1UniswapV3Market computes wrong market liquidity

Handle cmichel Vulnerability details The OverlayV1UniswapV3Market.fetchPricePoint tries to compute the market depth in OVL terms as marketLiquidity in ETH / ovlPrice in ETH per OVL. To get the market liquidity in ETH and not the other token pair, it uses the ethIs0 boolean. marketLiquidity = ethI...

Diffie-Hellman Key Agreement Protocol 资源管理错误漏洞

The Diffie-Hellman Key Agreement Protocol is a key negotiation protocol. It was originally described in Diffie and Hellman's seminal paper on public key cryptography. The key negotiation protocol allows Alice and Bob to exchange public key values and securely compute a shared key K based on...
