MassDNS is a simple high-performance DNS stub resolver targetting those who seek to resolve a massive amount of domain names in the order of millions or even billions. Without special configuration, MassDNS is capable of resolving over 350,000 names per second using publicly available resolvers...

Denial Of Service (DoS)

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: A memory leak flaw was found in the way the Linux kernel's memory subsystem handled resource clean up in the mmap failure path when the MAPHUGETLB flag was set...

Denial Of Service (DoS)

The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: A flaw was found in the way the Linux kernel's Event Poll epoll subsystem handled large, nested epoll structures. A local, unprivileged user could use this flaw t...

Denial Of Service (DoS)

kernel-rt is vulnerable to denial of service DoS attacks. The vulnerability exists as the epoll implementation in the Linux kernel 2.6.37.2 and earlier does not properly traverse a tree of epoll file descriptors, which allows local users to cause a denial of service through a crafted application...

Security update for the Linux Kernel (important)

The openSUSE Leap 42.2 kernel was updated to 4.4.92 to receive various security and bugfixes. The following security bugs were fixed: - CVE-2017-13080: Wi-Fi Protected Access WPA and WPA2 allowed reinstallation of the Group Temporal Key GTK during the group key handshake, allowing an attacker...

libevent Denial of Service Vulnerability

libevent is an event-triggered network library for windows, linux, bsd and other platforms, the internal use of select, epoll, kqueue and other system calls to manage the event mechanism. A denial of service vulnerability exists in libevent. An attacker can exploit this vulnerability to crash an...

[SECURITY] Fedora 25 Update: python-tornado-4.4.2-1.fc25

Tornado is an open source version of the scalable, non-blocking web server and tools. The framework is distinct from most mainstream web server frameworks and certainly most Python frameworks because it is non-blocking and reasonably fast. Because it is non-blocking and uses epoll, it can handle...

The vulnerability of the Linux operating system, which allows a hacker to trigger a service failure

The vulnerability of the system call epollctl fs/eventpoll.c in the Linux operating system arises from the improper handling of the ELOOP error in operations like EPOLLCTLADD. Exploiting this vulnerability allows a local attacker to cause a service to terminate abnormally through a specially...
