sshd in OpenSSH before 7.3, when SHA256 or SHA512 are used for user password hashing, uses BLOWFISH hashing on a static password when the username does not exist, which allows remote attackers to enumerate users by leveraging the timing difference between responses when a large password is provid...

The vulnerability of the Cisco Unified Communications Manager software allows a malicious actor to execute arbitrary code.

The GNU Bash command shell, as of version 4.3 and later, incorrectly handles lines that follow the declaration of a function that is exported as a variable. This allows a malicious actor to execute arbitrary code by interfering with environment variables. Security researchers have confirmed that...
