F5 Networks BIG-IP : Diffie-Hellman key exchange protocol vulnerability (K000148343)

The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the K000148343 advisory. Validating the order of the public keys in the Diffie-Hellman Key Agreement Protocol, when an approved safe prime is...

CVE-2024-41996

Validating the order of the public keys in the Diffie-Hellman Key Agreement Protocol, when an approved safe prime is used, allows remote attackers from the client side to trigger unnecessarily expensive server-side DHE modular-exponentiation calculations. The client may cause asymmetric resource...

Diffie-Hellman 安全漏洞

Diffie-Hellman is a key negotiation protocol open-sourced by Diffie-Hellman. This key negotiation protocol allows Alice and Bob to exchange public key values and securely compute the shared key K based on knowledge of these values and their own corresponding private keys, enabling further secure...

Potential Gas and Overflow Issues with Decimal Shift Left in _convertDecimals Function

Lines of code Vulnerability details Impact The exponentiation operation in the decimal shift left scenario can lead to high gas consumption and potential integer overflow. The gas cost and risk of overflow increase with the value of the exponent, which could make the function expensive or even...

Incorrect Results In Exponentiation

gnark-crypto is vulnerable to Incorrect Results in Exponentiation. The vulnerability is due to the use of exponentiation à la GLV ExpGLV when the exponent exceeds the group order of the pairing target group GT. This sometimes results in incorrect outcomes compared to normal exponentiation Exp...

GHSA-PFFG-92CG-XF5C gnark-crypto's exponentiation in the pairing target group GT using GLV can give incorrect results

Impact When the exponent is bigger than r, the group order of the pairing target group GT, the exponentiation à la GLV ExpGLV can sometimes give incorrect results compared to normal exponentiation Exp. The issue impacts all users using ExpGLV for exponentiations in GT. This does not impact Exp an...

Siemens SCALANCE W1750D Uncontrolled Resource Consumption (CVE-2002-20001)

The Diffie-Hellman Key Agreement Protocol allows remote attackers from the client side to send arbitrary numbers that are actually not public keys, and trigger expensive server-side DHE modular- exponentiation calculations, aka a DHEater attack. The client needs very little CPU resources and...

IO FinNet tss-lib vulnerable to timing attack from non-constant time scalar arithmetic

io.finnet tss-lib before 2.0.0 can leak the lambda value of a private key via a timing side-channel attack because it relies on Go big.Int, which is not constant time for Cmp, modular exponentiation, or modular inverse. An example leak is in crypto/paillier/paillier.go. bnb-chain/tss-lib and...

SUSE CVE-2015-0837

The mpipowm function in Libgcrypt before 1.6.3 and GnuPG before 1.4.19 allows attackers to obtain sensitive information by leveraging timing differences when accessing a pre-computed table during modular exponentiation, related to a "Last-Level Cache Side-Channel Attack."...

SUSE CVE-2016-0702

The MODEXPCTIMECOPYFROMPREBUF function in crypto/bn/bnexp.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g does not properly consider cache-bank access times during modular exponentiation, which makes it easier for local users to discover RSA keys by running a crafted application on the...

SUSE CVE-2022-40735

The Diffie-Hellman Key Agreement Protocol allows use of long exponents that arguably make certain calculations unnecessarily expensive, because the 1996 van Oorschot and Wiener paper found that "appropriately short exponents" can be used when there are adequate subgroup constraints, and these sho...
