Problem description

Some vulnerabilities were discovered and corrected in the Linux 2.6
kernel:

The 2.6 kernel prior to 2.6.12 allows remote attackers to poison the
bridge forwarding table using frames that have already been dropped by
filtering, which can cause the bridge to forward spoofed packets
(CVE-2005-3272).

Prior to 2.6.15.5, the kernel allows local users to cause a DoS
("endless recursive fault") via unknown attack vectors related to a
"bad elf entry address" on Intel processors (CVE-2006-0741).

A race condition in the socket buffer handling in the 2.6.9 kernel and
earlier versions could allow a remote attacker to cause a DoS (crash)
(CVE-2006-2446).

Stephane Eranian discovered an issue with permon2.0 where, under
certain circumstances, the perfmonctl() system call may not correctly
manage the file descriptor reference count, resulting in the system
possibly running out of file structure (CVE-2006-3741).

Prior to and including 2.6.17, the Universal Disk Format (UDF)
filesystem driver allowed local users to cause a DoS (hang and crash)
via certain operations involving truncated files (CVE-2006-4145).

Various versions of the Linux kernel allowed local users to cause a DoS
(crash) via an SCTP socket with a certain SO_LINGER value, which is
possibly related to the patch used to correct CVE-2006-3745
(CVE-2006-4535).

The __block_prepate_write function in the 2.6 kernel before 2.6.13 does
not properly clear buffers during certain error conditions, which
allows users to read portions of files that have been unlinked
(CVE-2006-4813).

The clip_mkip function of the ATM subsystem in the 2.6 kernel allows
remote attackers to dause a DoS (panic) via unknown vectors that cause
the ATM subsystem to access the memory of socket buffers after they are
freed (CVE-2006-4997).

The seqfile handling in the 2.6 kernel up to 2.6.18 allows local users
to cause a DoS (hang or oops) via unspecified manipulations that
trigger an infinite loop while searching for flowlabels
(CVE-2006-5619).

A missing call to init_timer() in the isdn_ppp code of the Linux kernel
can allow remote attackers to send a special kind of PPP pakcet which
may trigger a kernel oops (CVE-2006-5749).

The aio_setup_ring() function initializes a variable incorrectly which
can be used in error path to free allocated resources which could allow
a local user to crash the node (CVE-2006-5754).

A vulnerability in the bluetooth support could allow for overwriting
internal CMTP and CAPI data structures via malformed packets
(CVE-2006-6106).

The provided packages are patched to fix these vulnerabilities. All
users are encouraged to upgrade to these updated kernels immediately
and reboot to effect the fixes.
