Linux Kernel Sendpage Local Privilege Escalation
Posted Jul 19, 2012
Authored by Brad Spengler, Ramon de C Valle, Tavis Ormandy, Julien Tinnes, egypt | Site metasploit.com

The Linux kernel failed to properly initialize some entries the proto_ops struct for several protocols, leading to NULL being derefenced and used as a function pointer. By using mmap(2) to map page 0, an attacker can execute arbitrary code in the context of the kernel. Several public exploits exist for this vulnerability, including spender's wunderbar_emporium and rcvalle's ppc port, sock_sendpage.c. All Linux 2.4/2.6 versions since May 2001 are believed to be affected: 2.4.4 up to and including 2.4.37.4; 2.6.0 up to and including 2.6.30.4

Libc sigqueue() Function TGKILL si_code Spoof
Posted Mar 23, 2011
Authored by Julien Tinnes

Libc's sigqueue() function has not been updated to mitigate spoofing of the TGKILL si_code. Because of this, userland is unable to trust the pid and uid information of a TKILL signal.
