Command-line Network Packet Crafting and Injection Utility: nemesis

The Nemesis Project is designed to be a command line based, portable human IP stack for UNIX-like and Windows systems. The suite is broken down by protocol, and should allow for useful scripting of injected packets from simple shell scripts. Key Features ARP/RARP, DNS, ETHERNET, ICMP, IGMP, IP,...

Fast and More Efficient Stateless SYN Scanner And Banner Grabber: PolarBearScan

polarbearscan is an attempt to do faster and more efficient banner grabbing and port scanning. It combines two different ideas which hopefully will make it somewhat worthy of your attention and time. The first of these ideas is to use stateless SYN scanning using cryptographically protected cooki...

CVE-2015-3913

CVE-2015-3913 affects Huawei Campus series switch IP stacks. According to Huawei’s advisory HWPSIRT-2015-02003, the vulnerability arises from improper handling of IP options in the IP stack when processing crafted ICMP requests, which can cause a board reboot (denial of service). Other connected ...

openSUSE Security Update : the Linux Kernel (openSUSE-2016-1426)

The openSUSE Leap 42.2 kernel was updated to 4.4.36 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended...

Updated kernel packages fix security vulnerabilities

This update is based on the upstream 4.4.30 kernel and fixes at least these security issues: The filesystem implementation in the Linux kernel through 4.8.2 preserves the setgid bit during a setxattr call, which allows local users to gain group privileges by leveraging the existence of a setgid...

Important: kernel

Issue Overview: The IP stack in the Linux kernel before 4.6 allows remote attackers to cause a denial of service stack consumption and panic or possibly have unspecified other impact by triggering use of the GRO path for packets with tunnel stacking, as demonstrated by interleaved IPv4 headers an...
