DESCRIPTION:
Debian has issued an update for linux-2.6. This fixes multiple
vulnerabilities, which can be exploited by malicious, local users to
cause a DoS (Denial of Service), gain escalated privileges, or to
disclose certain system and potentially sensitive information, and by
malicious people to cause a DoS (Denial of Service) or potentially
compromise a vulnerable system.

1) An error withing the Econet protocol implementation can be
exploited to cause a stack overflow by sending specially crafted
network traffic.

2) An error within the "econet_sendmsg()" function in
net/econet/af_econet.c when handling remote addresses can be
exploited to cause a crash.

3) An error within the "ec_dev_ioctl()" function in
net/econet/af_econet.c incorrectly enforces access restriction, which
can be exploited to assign an Econet address to arbitrary interfaces.

4) The "get_name()" function in net/tipc/socket.c is not properly
initializing a structure before copying it to userspace. This can be
exploited to disclose potentially sensitive information.

SOLUTION:
Apply updated packages.
