kernel: net: IPv6 fragmentation implementation of nexthdr field may be associated with an invalid option

The IPv6 fragmentation implementation in the Linux kernel does not consider that the nexthdr field may be associated with an invalid option, which allows local users to cause a denial of service out-of-bounds read and BUG or possibly have unspecified other impact via crafted socket and send syste...

Denis and Co.

In April 2017, we published a detailed review of a malicious program that used DNS tunneling to communicate to its C&C. That study prompted us to develop a technology to detect similar threats, which allowed us to collect a multitude of malware samples using DNS tunneling. In this article, we wil...

CVE-2018-5703

The tcpv6synrecvsock function in net/ipv6/tcpipv6.c in the Linux kernel through 4.14.11 allows attackers to cause a denial of service slab out-of-bounds write or possibly have unspecified other impact via vectors involving TLS...

Compromising IPv4 Networks via IPv6: mitm6

mitm6 is a pentesting tool that exploits the default configuration of Windows to take over the default DNS server. It does this by replying to DHCPv6 messages, providing victims with a link-local IPv6 address and setting the attackers host as default DNS server. As DNS server, mitm6 will...
