Description:
Ferenczi Viktor has discovered a weakness in Debian, which can be exploited by malicious, local users to bypass certain security restrictions and potentially cause a DoS (Denial of Service).
The weakness is caused due to the "/var/log/debian-installer/cdebconf" directory being left behind with world-writable permissions after completion of installation using the network install CD. This can potentially be exploited by malicious users to cause a DoS by e.g. filling up the /var/log partition.
The vulnerability has been confirmed in debian-31r1a-i386-netinst.iso and also reported in version 3.1r1. Other versions may also be affected.
