The Stable team (Linux kernel developers) have announced the release of Linux kernel 2.6.25.11.They have strongly recommended any one who uses Linux kernel 2.6.25 on multiuser x86-64 system to upgrade to the vesion 2.6.25.11. The user with restriced previlleges are able to escalate their access previlleges. The announcer has not given any details of the vulnerability but it was supposed to caused by the filtereing of the LDT. |

Pin locked USB- affordable security for your data |
|
|
Sunday, 13 July 2008 |
Corsaur's padlock USB dirve provides PIN lock to provide unauthorised access to your data. It has a built in key pad to enter the pin number to enter the pin code.If it is locked, any computer that it is plugged into won't detect it as a USB device until the correct PIN is entered.This prevents any unauthorized access or "Brute Force" attack to the data on Flash Padlock. Users can program in a PIN, much like they do for an ATM machine, to lock/unlock their data. An easy to use keypad in conjunction with lock/unlock indicator lights makes the Flash Padlock highly intuitive to use.non-replaceable battery allows the PIN to be keyed-in before the stick is inserted into the USB port. The Padlock is a cross-platform device that does not need drivers.

Root exploit for Linux kernel in circulation |
|
|
Tuesday, 12 February 2008 |
|
Two exploits have been published for a security vulnerability in the Linux kernel. They allow restricted users to escalate their privileges to that of the superuser. Systems on which multiple users work in parallel are particularly at risk of an attacker exploiting the vulnerability to manipulate or gain control of a system. In tests by the heise Security editorial team, one of the exploits opened a shell with root privileges on an Ubuntu system. |

Multiple critical vulnerabilities in MPlayer |
|
|
Thursday, 07 February 2008 |
|
Three patches have been published for the open source MPlayer media player which close several security holes. The flaws allow attackers to provoke buffer overflows in components of the player. A buffer overflow in the url_escape_string function in the stream/url.c file can be provoked when processing certain URLs. An array indexing error can occur in the mov_build_index function in the libmpdemux/demux_mov.c file when parsing crafted MOV files. Comments in FLAC files can provoke a buffer overflow in get_flac_metadata (libmpdemux/demux_audio.c). A buffer overflow can be provoked in the code that evaluates responses from CDDB servers. Versions 1.0cr2 and earlier are affected. If your source is from the Subversion repository, an update (svn up) is sufficient, otherwise the patches should be installed individually |

Barcode systems susceptible to serious hacker attacks |
|
|
Tuesday, 01 January 2008 |
|
Experts say that the Barcodes our highly automated business world could now hardly do without, often display serious security holes. In particular, one- or two-dimensional systems of barcodes and matrix codes are open to common hacker attacks and to experiments that have had variable results. This was stated by "FX" of the Phenoelit group at the 24th Chaos Communication congress (24C3) in Berlin on Friday evening. Frequently, he said, all you had to do was simply copy "used" barcodes in a copyshop, or scan them in and print them out. |

Wireshark network analysis tool version 0.99.7 available |
|
|
Wednesday, 19 December 2007 |
|
The Wireshark project has marked version 0.99.7 of the open source network analysis tool as stable and released it for public consumption. Security vulnerabilities in a number of software modules were reported just under a month ago. The new version fixes these vulnerabilities. Remote attackers can exploit the bugs to cause previous versions of the software to enter an infinite loop, crash or possibly to inject arbitrary code. |
