Linux Kernel 2.6.x PRCTL Core Dump Handling – Local r00t Exploit ( BID 18874 / CVE-2006-2451 )

Use Netsparker


A working version of the exploit used to escalate privileges to root in the recent Debian breakin, ah another root kernel exploit.

It’s to do with the way the kernel handles file permissions (or lack of) on core dumps.

Linux kernel is prone to a local privilege-escalation vulnerability.

A local attacker may gain elevated privileges by creating a coredump file in a directory that they do not have write access to.

A successful attack may result in a complete compromise.

Linux kernel versions prior to 2.6.17.4 are vulnerable.
