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

For more information:
SA35265
SA38601
SA39490

1) An error within the SCTP subsystem can be exploited to cause a
crash by sending a specially crafted init package.

2) An error exists within the implementation of the TIPC protocol,
which can be exploited by malicious, local users to cause a NULL
pointer dereference by sending datagrams through AF_TIPC before
entering the network mode.

3) An error exists within the kgdb implementation for the PowerPC
architecture, which can be exploited by malicious, local users to
write to kernel memory.

NOTE: This does not affect the binary kernels packages.

4) An error exists within the implementation of the GFS2 file system,
which can be exploited by malicious, local users to trigger a
"BUG()".

5) The "nfs_release_request()" function in fs/nfs/pagelist.c can be
interrupted, which can be exploited to e.g. cause a NULL pointer
dereference by killing an application while it performs certain
actions on an NFS file.

SOLUTION:
Apply updated packages.
