Null pointer dereference

The ipfragreasm function in net/ipv4/ipfragment.c in the Linux kernel 2.6.32-rc8, and 2.6.29 and later versions before 2.6.32, calls IPINCSTATSBH with an incorrect argument, which allows remote attackers to cause a denial of service NULL pointer dereference and hang via long IP packets, possibly...

FreeBSD -- arc4random(9) predictable sequence vulnerability

Security Best Practice: Protect Yourself from Ping of Death Attacks

A Ping of Death POD is a type of attack on a computer that involves sending a malformed or otherwise malicious ping to a computer. A ping is normally 56 bytes in size or 84 bytes when IP header is considered; historically, many computer systems could not handle a ping packet larger than the maxim...

Security Best Practice: Familiarize Yourself with the Time to Live (TTL) Masking Protection

Each IP packet has a field called "Time to Live", or TTL. Each router along the way decrements this value by one. When the router decrements this value to zero it drops the packet and sends an ICMP notifying about the event...
