CVE-2006-0454

Linux kernel before 2.6.15.3 down to 2.6.12, while constructing an ICMP response in icmpsend, does not properly handle when the ipoptionsecho function in icmp.c fails, which allows remote attackers to cause a denial of service crash via vectors such as 1 record-route and 2 timestamp IP options wi...

CVE-2006-0454

The CVE-2006-0454 issue affects the Linux kernel (2.6.x) where icmp_send mishandles failures in ip_options_echo, enabling remote attackers to crash the host via crafted ICMP options (record-route, timestamp with needaddr and truncated value). Public advisories from SUSE, Red Hat, Fedora, Ubuntu d...

Verified evasion in Snort

pre Dan Kaminsky gave a presentation at shmoocon and mentioned using ip fragmentation timers to evade intrusion detection systems. It's a pretty straightforward technique and easy to code up so we decided to look and see if Snort was vulnerable...

security flaw

Memory leak in the icmppushreply function in Linux 2.6 before 2.6.12.6 and 2.6.13 allows remote attackers to cause a denial of service memory consumption via a large number of crafted packets that cause the ipappenddata function to fail, aka "DST leak in icmppushreply."...

CVE-2006-0054

Affected component: FreeBSD ipfw (6.0-RELEASE). Vulnerability: Remote attackers can crash the firewall by sending ICMP IP fragments that match actions (reset, reject, unreach), causing an access to an uninitialized pointer. Impact: Denial of service via firewall crash. Root cause: Incorrect handl...

PT-2006-1142 · Freebsd · Freebsd

Name of the Vulnerable Software and Affected Versions: FreeBSD version 6.0-RELEASE Description: The issue allows remote attackers to cause a denial of service, leading to a firewall crash. This is achieved through ICMP IP fragments that match a reset, reject, or unreach action, resulting in acces...

ipfw -- IP fragment denial of service

Problem description: The firewall maintains a pointer to layer 4 header information in the event that it needs to send a TCP reset or ICMP error message to discard packets. Due to incorrect handling of IP fragments, this pointer fails to get initialized. Impact: An attacker can cause the firewall...
