  • A couple more pictures here.
  • Even more p0r… err.. Pics here.

Critical Security Flaw Silently Patched

  • The attack allows a (unpriviliged) user process that has access to the X server (so, any GUI application) to unconditionally escalate to root.
  • It doesn’t take advantage of any bug in the X server!
  • Been an issue since Kernel 2.6 was released October 8th 2003

Root Privileges Through Linux Kernel Bug (Same story, different angle. Slashdot claims they are not related, despite the fact that they are.)

  • More of a conceptual issue.
  • The problem is in the memory management area of Linux allows local attackers to execute code at root level.
  • SUSE maintainer Andrea Arcangeli provided a fix for the problem in September 2004

C# comes to Android via MonoDroid

Linux Backup:

  1. fwbackups
    1. Great UI
    2. Supports multiple OSes
    3. Remote backup support
    4. Image backup support (not  positive on this)
  2. Mondo Rescue
    1. Backs up your GNU/Linux server or workstation to tape, CD-R, CD-RW, DVD-R[W], DVD+R[W], NFS or hard disk partition.
    2. Allows you to restore your computer from bare metal.
    3. It supports adjustments in disk geometry, including migration from non-RAID to RAID.
  3. Back in Time
    1. Inspired from “flyback project” and “TimeVault”.
    2. Keep in mind that Back In Time is just a GUI. The real magic is done by rsync (take snapshots and restore), diff (check if somethind changed) and cp (make hardlinks).
    3. A new snapshot is created only if something changed since the last snapshot (if any).

Chris’ favorite for a network: BackupPC

Data Rescue:
ddrescue – Copies data (best effort) from bad sectors to good sectors
dd_rhelp – A nice tool to make using ddrescue easier.
