kernel: IP fragments with random offsets allow a remote denial of service (FragmentSmack)

A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment reassembly algorithm by sending specially crafted packets which could lead to a CPU...

kernel: a bug in ip_frag_reasm() can cause a crash in ip_do_fragment()

A security flaw was found in the ipfragreasm function in net/ipv4/ipfragment.c in the Linux kernel which can cause a later system crash in ipdofragment. With certain non-default, but non-rare, configuration of a victim host, an attacker can trigger this crash remotely, thus leading to a remote...

QEMU: slirp: heap buffer overflow while reassembling fragmented datagrams

A heap buffer overflow issue was found in the way SLiRP networking back-end in QEMU processes fragmented packets. It could occur while reassembling the fragmented datagrams of an incoming packet. A privileged user/process inside guest could use this flaw to crash the QEMU process resulting in DoS...

RHEL 7 : kernel (RHSA-2018:2785)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2785 advisory. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: A flaw named SegmentSmack was found in...

DEBIAN-CVE-2018-5391

The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation...

CVE-2018-6923

In FreeBSD before 11.1-STABLE, 11.2-RELEASE-p2, 11.1-RELEASE-p13, ip fragment reassembly code is vulnerable to a denial of service due to excessive system resource consumption. This issue can allow a remote attacker who is able to send an arbitrary ip fragments to cause the machine to consume...
