Google Testing Post-Quantum Cryptography in Chrome

Plenty has been speculated since the Snowden documents were made public about the NSA’s interest in building a quantum computer that could break current encryption securing communication worldwide. Quantum computing on a practical scale is a distant goal, but some do exist that leverage some...

The vulnerability of the Cisco Unified Communications Manager software allows a malicious individual to obtain a one-time code (nonce) for an ECDSA encryption algorithm.

The vulnerability exists in the implementation of the Montgomery algorithm in OpenSSL, due to the temporal impermanence of the operations involved in padding. Exploiting this vulnerability allows local users to obtain a one-time code nonce for ECDSA by attacking the cache through external channel...

The vulnerability of the OpenSSL software allows a malicious attacker to compromise the confidentiality, integrity, and accessibility of protected information.

The state of the race function in sslparseserverhellotlsext in t1lib.c of OpenSSL, when multiprocessing and session resumption are used, allows remote SSL servers to cause service interruptions such as memory reallocation and unexpected termination of applications, or otherwise affect the system ...

The vulnerability of the Firefox browser, which allows a malicious actor to trigger a service failure

Mozilla Firefox browser contains a vulnerability related to errors in the implementation of a certain type of key verification mechanism in the crypto.generateCRMFRequest method. Exploiting this vulnerability allows malicious actors, operating remotely, to cause a service failure abnormal...

The vulnerability of the Mozilla SeaMonkey software package, which allows a malicious individual to trigger a service failure

The Mozilla SeaMonkey browser contains a vulnerability related to errors in the implementation of a certain type of key verification mechanism in the cryptoGenerateCRMFRequest method. Exploiting this vulnerability allows malicious actors to induce a service failure abnormal termination of the...

SUSE-SU-2016:1457-1 Security update for cyrus-imapd

Previous versions of cyrus-imapd would not allow its users to disable old protocols like SSLv1 and SSLv2 that are unsafe due to various known attacks like BEAST and POODLE. https://bugzilla.cyrusimap.org/showbug.cgi?id=3867 remedies this issue by adding the configuration option 'tlsversions' to...

openssl: use-after-free on invalid EC private key import

A use-after-free flaw was found in the way OpenSSL imported malformed Elliptic Curve private keys. A specially crafted key file could cause an application using OpenSSL to crash when imported...

Botan Downgrade Vulnerability

Botan is a C++ library of cryptographic algorithms that supports AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. A degradation vulnerability exists in Botan versions 1.11.x prior to 1.11.29, which stems from the program's failure to enforce a TLS policy on the signature algorithm and the ECC ellipt...

UBUNTU-CVE-2016-2195

Integer overflow in the PointGFp constructor in Botan before 1.10.11 and 1.11.x before 1.11.27 allows remote attackers to overwrite memory and possibly execute arbitrary code via a crafted ECC point, which triggers a heap-based buffer overflow. The bigintmul and bigintsqr functions received the...

Botan ECDSA Bypass Attack Vulnerability

Botan is a C++ library of cryptographic algorithms that supports AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. A security vulnerability exists in Botan that allows remote attackers to exploit the vulnerability to perform a bypass attack on ECDSA...

nss: Use-after-free in NSS during SSL connections in low memory (MFSA 2016-15)

A use-after-free flaw was found in the way NSS handled DHE Diffie–Hellman key exchange and ECDHE Elliptic Curve Diffie-Hellman key exchange handshake messages. A remote attacker could send a specially crafted handshake message that, when parsed by an application linked against NSS, would cause th...

CVE-2015-7511

CVE-2015-7511 affects Libgcrypt up to version 1.6.4 (pre-1.6.5). The issue is an improper elliptic‑point curve multiplication during decryption that enables physical side‑channel leakage of ECDH private keys via electromagnetic emanations. Remediation is upgrading Libgcrypt to fixed releases (e.g...
