The Unidirectional Lightweight Encapsulation ULE decapsulation component in dvb-core/dvbnet.c in the dvb driver in the Linux kernel 2.6.17.8 allows remote attackers to cause a denial of service crash via an SNDU length of 0 in a ULE packet...

SUSE CVE-2014-8160

net/netfilter/nfconntrackprotogeneric.c in the Linux kernel before 3.18 generates incorrect conntrack entries during handling of certain iptables rule sets for the SCTP, DCCP, GRE, and UDP-Lite protocols, which allows remote attackers to bypass intended access restrictions via packets with...

SUSE 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...

SUSE CVE-2017-15192

In Wireshark 2.4.0 to 2.4.1 and 2.2.0 to 2.2.9, the BT ATT dissector could crash. This was addressed in epan/dissectors/packet-btatt.c by considering a case where not all of the BTATT packets have the same encapsulation level...

SUSE CVE-2019-19330

The HTTP/2 implementation in HAProxy before 2.0.10 mishandles headers, as demonstrated by carriage return CR, ASCII 0xd, line feed LF, ASCII 0xa, and the zero character NUL, ASCII 0x0, aka Intermediary Encapsulation Attacks...
