OpenSSH has recently discovered two vulnerabilities that could potentially lead to “Man in the middle” (MITM) attacks and denial of service (DOS) under specific conditions.
The first vulnerability, CVE-2016-10708, allows an attacker to potentially force a client to reuse a previously used session ID, which could lead to an MITM attack. The second vulnerability, CVE-2016-10707, could result in a situation where an attacker could trigger a null-pointer dereference by sending a maliciously crafted packet, resulting in a denial of service.
DOS, which stands for Disk Operating System, was a popular operating system for personal computers in the 1980s and early 1990s. Designed to manage operations with hard drives and other data storage devices like floppy disks, DOS operates through a command line interface where users can input commands directly into the system. Users can perform various functions such as running applications, navigating the file system, creating and deleting files, formatting discs, and more using DOS commands.
