วงการ admin สะเทือน งานเข้ากันเต็มๆ เมื่อ ssl library ยอดฮิต อย่าง openssl เป็นเป้า ตาม Heartbleed attack เลยต้องอัพเดต กัน โดยเฉพาะเครื่องเก่าๆ ส่วนผม มีเครื่องนึงที่เป็น ubuntu precise 12.04 เลยต้องลงไม้ลงมือกันหน่อย

ที่ทำไม่ได้ไรมาก จากการตรวจสอบ พบว่า ตาม USN-2165-1: OpenSSL vulnerabilities http://www.ubuntu.com/usn/usn-2165-1/ ได้ระบุวิธีไว้แล้ว
Ubuntu 12.04 LTS:
libssl1.0.0 1.0.1-4ubuntu5.12

พอดู เป็นลิงก์ไปยัง source package
เริ่มจาก update source กัน .ให้แน่ใจว่าเปิด repo precise-security/main อยู่ แล้ว
จากนั้นติดตั้ง package ที่จำเป็นในการ build

  1. root@campus:~# apt-get update
  2. root@campus:~# apt-get upgrade
  3. root@campus:~# apt-get install devscripts
  4. root@campus:~# apt-get build-dep openssl
  5. root@campus:~# apt-get source openssl
  6. root@campus:~# apt-get source openssl

เมื่อเสร็จสิ้น จะได้ dpkg เพื่อลงทับอันเก่า
