fastnetmon

Community Edition FastNetMon - A high-performance DDoS detector/sensor built on top of multiple packet capture engines: NetFlow, IPFIX, sFlow, AFPACKET port mirror. What do we do? We detect hosts in the deployed network sending or receiving large volumes of traffic, packets/bytes/flows per second...

tcpreplay

Tcpreplay Tcpreplay is a suite of GPLv3 licensed utilities for UNIX and Windows under Cygwin for editing and replaying network traffic previously captured by tools like tcpdump and Wireshark. It classifies traffic as client or server, rewrites Layer 2/3/4 headers, and replays it back onto the...

CVE-2022-23085

A user-provided integer option was passed to nmreqcopyin without checking if it would overflow. This insufficient bounds checking could lead to kernel memory corruption. On systems configured to include netmap in their devfsruleset, a privileged process running in a jail can affect the host...

CVE-2022-23085

A user-provided integer option was passed to nmreqcopyin without checking if it would overflow. This insufficient bounds checking could lead to kernel memory corruption. On systems configured to include netmap in their devfsruleset, a privileged process running in a jail can affect the host...

CVE-2022-23084

The total size of the user-provided nmreq to nmreqcopyin was first computed and then trusted during the copyin. This time-of-check to time-of-use bug could lead to kernel memory corruption. On systems configured to include netmap in their devfsruleset, a privileged process running in a jail can...

Memory corruption

The total size of the user-provided nmreq to nmreqcopyin was first computed and then trusted during the copyin. This time-of-check to time-of-use bug could lead to kernel memory corruption. On systems configured to include netmap in their devfsruleset, a privileged process running in a jail can...

CVE-2022-23084

CVE-2022-23084 concerns the FreeBSD netmap component. The vulnerability is a time-of-check to time-of-use bug in nmreq_copyin(): the total size of a user-provided nmreq is computed and then trusted during the copy, enabling kernel memory corruption. Impact requires netmap in devfs_ruleset; a priv...

CVE-2022-23085: Out-of-bounds Write

A user-provided integer option was passed to nmreqcopyin without checking if it would overflow. This insufficient bounds checking could lead to kernel memory corruption. On systems configured to include netmap in their devfsruleset, a privileged process running in a jail can affect the host...

CVE-2022-23084: Time-of-check Time-of-use (TOCTOU) Race Condition

The total size of the user-provided nmreq to nmreqcopyin was first computed and then trusted during the copyin. This time-of-check to time-of-use bug could lead to kernel memory corruption. On systems configured to include netmap in their devfsruleset, a privileged process running in a jail can...

The vulnerability of the nmreq_copyin() function in the netmap component of FreeBSD allows a hacker to execute arbitrary code in the kernel context.

The vulnerability of the nmreqcopyin function in the netmap component of FreeBSD operating systems is caused by a numerical overflow. Exploiting this vulnerability could allow an attacker to execute arbitrary code within the kernel context...

The vulnerability of the nmreq_copyin() function in the netmap component of FreeBSD allows a hacker to execute arbitrary code.

The vulnerability of the nmreqcopyin function in the netmap component of FreeBSD operating systems is related to synchronization errors when using shared resources. Exploiting this vulnerability allows an attacker to execute arbitrary code within the kernel context...

FreeBSD Kernel Netmap Time-Of-Check Time-Of-Use Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on affected installations of FreeBSD Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of...
