The vulnerability of the ip6gre_err function in the Linux operating system, which allows a hacker to exert undefined effects

The vulnerability of the ip6greerr function in the Linux operating system is related to reading beyond the buffer boundaries. Exploiting this vulnerability can allow a remote attacker to exert unpredictable effects using vectors that include GRE flags in IPv6 packets...

tcpdump buffer overflow vulnerability (CNVD-2017-02325)

tcpdump is a set of sniffing tools developed by the Tcpdump team that run under the command line. The tool allows users to intercept and display TCP/IP and other packets sent or received over a network connection to that computer. A buffer overflow vulnerability exists in several functions of the...

UBUNTU-CVE-2017-5342

In tcpdump before 4.9.0, a bug in multiple protocol parsers Geneve, GRE, NSH, OTV, VXLAN and VXLAN GPE could cause a buffer overflow in print-ether.c:etherprint...

DEBIAN-CVE-2016-8666

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 and GRE headers, a...

kernel: Remotely triggerable recursion in GRE code leading to kernel crash

A flaw was found in the way the Linux kernel's networking subsystem handled offloaded packets with multiple layers of encapsulation in the GRO Generic Receive Offload code path. A remote attacker could use this flaw to trigger unbounded recursion in the kernel that could lead to stack corruption,...
