CVE-2024-31497
In PuTTY 0.68 through 0.80 before 0.81, biased ECDSA nonce generation allows an attacker to recover a user's NIST P-521 secret key via a quick attack in approximately 60 signatures. This is especially important in a scenario where an adversary is able to read messages signed by PuTTY or Pageant...

PT-2023-9405
Name of the Vulnerable Software and Affected Versions WolfSSL affected versions not specified Description The issue is related to the generation of the ECDSA nonce k, where a random number r is selected and then reduced modulo n, the order of the elliptic curve. The division used during the...

Issue Overview: When importing a curve25519 private key in PKCS8format with leading 0x00 bytes, it is possible to trigger an out-of-bounds read in the Network Security Services NSS library. This could lead to information disclosure. This vulnerability affects Firefox ESR 60.8, Firefox 68, and...
ALPINE-CVE-2020-12401
During ECDSA signature generation, padding applied in the nonce designed to ensure constant-time scalar multiplication was removed, resulting in variable-time execution dependent on secret data. This vulnerability affects Firefox 80 and Firefox for Android 80...
Side-channel Timing Attack
OpenSSL is vulnerable to side-channel timing attacks. These attacks are possible because the Montgomery ladder implementation doesn't run swap operations in constant time which makes it easier for local users to obtain ECDSA nonce values...
The vulnerability of Cisco IPS’ software allows a malicious individual to obtain a one-time code (nonce) for ECDSA encryption.
The vulnerability exists in the implementation of the Montgomery algorithm in OpenSSL, due to the temporal impermanence of the padding operations. Exploiting this vulnerability allows local users to obtain a one-time code nonce for ECDSA by attacking the cache through external channels using the...
EMC Documentum Content Server Multiple Vulnerabilities (ESA-2014-079)
The remote host is running a version of EMC Documentum Content Server that is affected by multiple vulnerabilities : - An error exists in the 'ssl3readbytes' function that permits data to be injected into other sessions or allows denial of service attacks. Note that this issue is exploitable only...
Security Advisory-Multiple OpenSSL vulnerabilities on Huawei products
This security advisory SA describes the impact of 7 OpenSSL vulnerabilities discovered in third-party software. The vulnerabilities are referenced in this document as follows: 1.SSL/TLS Man-in-the-Middle Vulnerability CVE-2014-0224. An unauthenticated, remote attacker with the ability to intercep...
Design/Logic Flaw
The Montgomery ladder implementation in OpenSSL through 1.0.0l does not ensure that certain swap operations have a constant-time behavior, which makes it easier for local users to obtain ECDSA nonces via a FLUSH+RELOAD cache side-channel attack...
