RSBAC 1.3.5 released


Arrow  SecurityAlert : 2911
Arrow  CVE : CVE-2007-3945
Arrow  SecurityRisk : Medium  Security Risk Medium  (About)
Arrow  Remote Exploit : Yes
Arrow  Local Exploit : No
Arrow  Exploit Available : No
Arrow  Credit : Amon Ott
Arrow  Published : 25.07.2007

Arrow  Affected Software : RSBAC 1.3.5



Arrow  Advisory Content :  

Hello everyone!

Rule Set Based Access Control (RSBAC) 1.3.5 has been released for both
Linux kernels 2.4.34.5 and 2.6.22.1.
You can download the new version from http://www.rsbac.org

RSBAC is one of the leading access control systems for the Linux
kernel with a good selection of access control models, see
http://www.rsbac.org/why for more details.

Important changes since 1.3.4:
* Fixes compilation errors with some configurations.
* Some safety measures with null pointers.
* Fixes an important bug with User Management password hashing,
introduced with newer 2.6 kernel crypto API.

Major improvements over the 1.2.x series:

Speed and scalability:
- Cache for inherited filesystem attribute values
- Automatically scaling hash tables for generic lists to minimize
list lookups
- Change network templates to handle up to 25 ip networks and up to
10 port ranges per template
- Various smaller optimizations

More control:
- Fine grained setuid control also in RC (type of the target user)
and ACL (acl at the target user) models
- UNIX sockets as new filesystem target type, thus more fine grained
control with RC types and ACLs
- Further improved IPC communication control
- RSBAC User Management password history with configurable length to
avoid password reuse.
- New request type AUTHENTICATE against USER targets. No
authentication against RSBAC UM without this right in RC and ACL, so
even harder to brute force attack

Amon.
