CVE-2020-14145

The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts where no host key for the server has been cached by the client. NOTE: some reports...

Name of the Vulnerable Software and Affected Versions: PuTTY versions 0.68 through 0.73 Description: The issue allows man-in-the-middle attackers to target initial connection attempts where no host key for the server has been cached by the client, due to an Observable Discrepancy leading to an...

CVE-2020-14002

PuTTY versions 0.68–0.73 have an observable discrepancy during algorithm negotiation that can leak information and enable MITM targeting the initial connection when no host key is cached. This is documented across multiple sources (DEBIAN/Mageia/Fedora advisories and Nessus plugin references) wit...

CVE-2020-3230

A vulnerability in the Internet Key Exchange Version 2 IKEv2 implementation in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to prevent IKEv2 from establishing new security associations. The vulnerability is due to incorrect handling of crafted IKEv2...

CVE-2019-9506 Encryption Key Negotiation of Bluetooth (KNOB) Vulnerability

The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks aka "KNOB" that can decrypt traffic and inject arbitrary...

kernel: memory leak in mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c

A flaw was found in the Linux kernel's mwifiex driver implementation when connecting to other WiFi devices in "Test Mode." A kernel memory leak can occur if an error condition is met during the parameter negotiation. This issue can lead to a denial of service if multiple error conditions meeting...

USN-4322-1: GnuTLS vulnerability

It was discovered that GnuTLS incorrectly handled randomness when performing DTLS negotiation. A remote attacker could possibly use this issue to obtain sensitive information, contrary to expectations...

CVE-2020-11501

GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 2018-07-16 because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks...
