Kernel: tcp: integer overflow while processing SACK blocks allows remote denial of service

An integer overflow flaw was found in the way the Linux kernel's networking subsystem processed TCP Selective Acknowledgment SACK segments. While processing SACK segments, the Linux kernel's socket buffer SKB data structure becomes fragmented. Each fragment is about TCP maximum segment size MSS...

The SUSE Linux Enterprise 15 Azure kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2019-11477: A sequence of SACKs may have been crafted such that one can trigger an integer overflow, leading to a kernel panic. - CVE-2019-11478: It was...

UBUNTU-CVE-2019-11479

Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote attacker could use this to cause a denial of service. This has been fixed in stable kerne...

Dissecting Weird Packets

I was investigating traffic in my home lab yesterday, and noticed that about 1% of the traffic was weird. Before I describe the weird, let me show you a normal frame for comparison's sake. This is a normal frame with Ethernet II encapsulation. It begins with 6 bytes of the destination MAC address...
