CVE-2018-0495

Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the gcryeccecdsasign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. T...

CVE-2018-0495

CVE-2018-0495 affects Libgcrypt prior to 1.7.10 and 1.8.x prior to 1.8.3. The root cause is a memory-cache side-channel (ROHNP) in the ECDSA signing path (_gcry_ecc_ecdsa_sign in cipher/ecc-ecdsa.c), enabling an attacker with local or co-resident VM access to recover ECDSA private keys. Mitigatio...

botan2 -- ECDSA side channel

botan2 developers report: A side channel in the ECDSA signature operation could allow a local attacker to recover the secret key. Found by Keegan Ryan of NCC Group. Bug introduced in 2.5.0, fixed in 2.7.0. The 1.10 branch is not affected...

CVE-2016-1000342

In the Bouncy Castle JCE Provider version 1.55 and earlier ECDSA does not fully validate ASN.1 encoding of signature on verification. It is possible to inject extra elements in the sequence making up the signature and still have it validate, which in some cases may allow the introduction of...

Bouncy Castle JCE Provider Design Vulnerability

Bouncy Castle JCE Provider is a Java-based encryption package. A security vulnerability exists in Bouncy Castle JCE Provider version 1.55 and earlier, which stems from ECDSA's failure to adequately validate signature encoding using ASN.1. An attacker can exploit the vulnerability to introduce...

CVE-2016-1000342

CVE-2016-1000342 is associated with Bouncy Castle JCE Provider up to version 1.55 and earlier, where ECDSA does not fully validate ASN.1 encoding of signatures during verification. This can allow injection of extra elements in the signature sequence and may permit the introduction of “invisible” ...
