kernel: Bluetooth implementations may not sufficiently validate elliptic curve parameters during Diffie-Hellman key exchange

A vulnerability in Bluetooth pairing potentially allows an attacker with physical proximity within 30 meters to gain unauthorized access via an adjacent network, intercept traffic and send forged pairing messages between two vulnerable Bluetooth devices. This may result in information disclosure,...

CVE-2019-14332

CVE-2019-14332 affects D-Link 6600-AP and DWL-3600AP (Ax 4.2.0.14). The issue is the use of weak SSH ciphers (e.g., diffie-hellman-group1-sha1) in affected firmware. Evidence in multiple sources confirms the vulnerability details and affected devices; some sources also reference related SSH brute...

nss: Empty or malformed p256-ECDH public keys may trigger a segmentation fault

Empty or malformed p256-ECDH public keys may trigger a segmentation fault due values being improperly sanitized before being copied into memory and used. This vulnerability affects Firefox ESR 60.8, Firefox 68, and Thunderbird 60.8...

SIAM Conference on Applied Algebraic Geometry 2019 - Isogenies mini-symposium

So here we are in the nice city of Bern, in the Teutonic Switzerland, for SIAM Conference on Applied Algebraic Geometry 2019 that this year counts more than 750 attendees! The weather is warm enough but the isogenies topic has never been so hot! So for this occurrence of the conference Tanja Lang...

libssh2 Input Validation Error Vulnerability

libssh2 is a client-side C library that implements the SSH2 protocol, which is capable of executing remote commands, file transfers, and providing a secure transmission channel for remote programs. An input validation error vulnerability exists in the...

UBUNTU-CVE-2019-13115

In libssh2 before 1.9.0, kexmethoddiffiehellmangroupexchangesha256keyexchange in kex.c has an integer overflow that could lead to an out-of-bounds read in the way packets are read from the server. A remote attacker who compromises a SSH server may be able to disclose sensitive information or caus...

CVE-2019-6629

On BIG-IP 14.1.0-14.1.0.5, undisclosed SSL traffic to a virtual server configured with a Client SSL profile may cause TMM to fail and restart. The Client SSL profile must have session tickets enabled and use DHE cipher suites to be affected. This only impacts the data plane, there is no impact to...

openssl: Malicious server can send large prime to client during DH(E) TLS handshake causing the client to hang

During key agreement in a TLS handshake using a DHE based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This...

Using Ed25519 signing keys for encryption

@Benjojo12 and I are building an encryption tool that will also support SSH keys as recipients, because everyone effectively already publishes their SSH public keys on GitHub. For RSA keys, this is dangerous but straightforward: a PKCS1 v1.5 signing key is the same as an OAEP encryption key...
