I. FRONT AND CENTER
---------------------
1.Rebinding attacks unbound
By Federico Biancuzzi
DNS rebinding was discovered in 1996 and affected the Java Virtual Machine (VM). Recently a group of researchers at Stanford found out that this vulnerability is still present in browsers and that the common solution, known as DNS pinning, is not effective anymore.

2.Aspect-Oriented Programming
By Rohit Sethi
Aspect-oriented programming (AOP) is a paradigm that is quickly gaining traction in the development world. At least partially spurred by the popularity of the Java Spring framework [1], people are beginning to understand the substantial benefits that AOP brings to development.

Perbandingan Linux vs FreeBSD vs OpenBSD  


linux (most of linux distribution):



Proteksi stack pake virtual address, randomize stack



handling overflow pakek SIGSEGV, stack bisa dioverwrite



mudah sekali bypass va







freebsd 6.1:



handling overflow pakek SIGSEGV, stack bisa di overwrite



bypass stack shield masih gagal coz i'm not freebsd user





openbsd 3.9:



handling overflow pakek SIGABRT, overflow di kill pakek sys_kill()



sulit sekali overwrite stack, proteksi non executable stack



it seems imposible to exploits stack overflow in openbsd





returning libc??sama kena SIGABRT







PoC :



linux http://student.te.ugm.ac.id/~phoenix03/compare.txt



freebsd ??



openbsd ??







Ada yang mau kasih tambahan referense bypass proteksi stack



di mesin bsd. thx jika ada referensi
