kernel: ipvlan: out-of-bounds write caused by unclear skb->cb

A flaw was found in the IPVLAN network driver in the Linux kernel. This issue is caused by missing skb-cb initialization in ipoptionsecho and can lead to an out-of-bounds write stack overflow. This may allow a local user to cause a denial of service or potentially achieve local privilege escalati...

DEBIAN-CVE-2019-16411

An issue was discovered in Suricata 4.1.4. By sending multiple IPv4 packets that have invalid IPv4Options, the function IPV4OptValidateTimestamp in decode-ipv4.c tries to access a memory region that is not allocated. There is a check for o-len data + 3" places one beyond the 3 bytes, because the...

Denial Of Service (DOS)

Linux kernel is vulnerable to denial of service DOS attacks. The vulnerability exists in the ipv4pktinfoprepare function in net/ipv4/ipsockglue.c in the Linux kernel. Malicious IP options present would cause the ipv4pktinfoprepare function to drop/free the dst. Attackers could cause a denial of...

ICMPExfil - Exfiltrate data with ICMP

ICMP Exfil allows you to transmit data via valid ICMP packets. You use the client script to pass in data you wish to exfiltrate, then on the device you're transmitting to you run the server. Anyone watching-- human or security system-- will just see valid ICMP packets, there's nothing malicious...
