7. Problem description:
Buffer overflows are present in the mars_nwe package. Since the code that contains these overflows is run as root, a local root compromise is possible if users create carefully designed directories and/or bindery objects.

A sample exploit has been made available.

Thanks go to Przemyslaw Frasunek (secure@freebsdf.lublin.pl) and Babcia Padlina Ltd. for noting the problem and providing a patch.

8. Solution:
For each RPM for your particular architecture, run:

rpm -Uvh filename

where filename is the name of the RPM.

9. Verification:


 MD5 sum                           Package Name

rpm --checksig --nopgp filename
