CVE-2020-2102

Jenkins 2.218 and earlier, LTS 2.204.1 and earlier used a non-constant time comparison function when validating an HMAC...

CVE-2020-2101

Jenkins 2.218 and earlier, LTS 2.204.1 and earlier did not use a constant-time comparison function for validating connection secrets, which could potentially allow an attacker to use a timing attack to obtain this secret...

GHSA-92VM-WFM5-MXVV cookie-signature Timing Attack

Affected versions of cookie-signature are vulnerable to timing attacks as a result of using a fail-early comparison instead of a constant-time comparison. Timing attacks remove the exponential increase in entropy gained from increased secret length, by providing per-character feedback on the...

BSA-2020-893

Security Advisory ID : BSA-2020-893 Component : OpenSSL Revision : 2.0: Final There is an overflow bug in the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and...

DEBIAN-CVE-2019-1551

There is an overflow bug in the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are...

PT-2019-4482

Name of the Vulnerable Software and Affected Versions OpenSSL versions 1.1.1 through 1.1.1d OpenSSL versions 1.0.2 through 1.0.2t Description The issue is related to an overflow bug in the x64 64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are...

Mbed TLS -- Side channel attack on ECDSA

Janos Follath reports: Our bignum implementation is not constant time/constant trace, so side channel attacks can retrieve the blinded value, factor it as it is smaller than RSA keys and not guaranteed to have only large prime factors, and then, by brute force, recover the key...

Flaw in Scalar::check_overflow allows side-channel timing attack

Versions of libsecp256k1 prior to 0.3.1 did not execute Scalar::checkoverflow in constant time. This allows an attacker to potentially leak information via a timing attack. The flaw was corrected by modifying Scalar::checkoverflow to execute in constant time...

Versions of libsecp256k1 prior to 0.3.1 did not execute Scalar::checkoverflow in constant time. This allows an attacker to potentially leak information via a timing attack. The flaw was corrected by modifying Scalar::checkoverflow to execute in constant time...

Timing attack on HMAC signature comparison in Apache Tapestry

The code which checks HMAC in form submissions used String.equals for comparisons, which results in a timing side channel for the comparison of the HMAC signatures. This could lead to remote code execution if an attacker is able to determine the correct signature for their payload. The comparison...

UBUNTU-CVE-2019-14318

Crypto++ 8.3.0 and earlier contains a timing side channel in ECDSA signature generation. This allows a local or remote attacker, able to measure the duration of hundreds to thousands of signing operations, to compute the private key used. The issue occurs because scalar multiplication in ecp.cpp...
