______________________________________________________________________________
An update that solves 7 vulnerabilities and has 46 fixes is
now available. It includes one version update.
Description:
The SUSE Linux Enterprise 11 Service Pack 1 kernel has been
updated to version 2.6.32.49 and fixes various bugs and
security issues.
* CVE-2011-3188: The TCP/IP initial sequence number
generation effectively only used 24 bits of 32 to generate
randomness, making a brute force man-in-the-middle attack
on TCP/IP connections feasible. The generator was changed
to use full 32bit randomness.
* CVE-2011-2699: Fernando Gont discovered that the IPv6
stack used predictable fragment identification numbers. A
remote attacker could exploit this to exhaust network
resources, leading to a denial of service.
* CVE-2011-2203: A NULL ptr dereference on mounting
corrupt hfs filesystems was fixed which could be used by
local attackers to crash the kernel.
* CVE-2011-1833: Added a kernel option to ensure
ecryptfs is mounting only on paths belonging to the current
ui, which would have allowed local attackers to potentially
gain privileges via symlink attacks.
* CVE-2011-1576: The Generic Receive Offload (GRO)
implementation in the Linux kernel allowed remote attackers
to cause a denial of service via crafted VLAN packets that
are processed by the napi_reuse_skb function, leading to
(1) a memory leak or (2) memory corruption, a different
vulnerability than CVE-2011-1478.
* CVE-2011-4330: A name overflow in the hfs filesystem
was fixed, where mounting a corrupted hfs filesystem could
lead to a stack overflow and code execution in the kernel.
This requires a local attacker to be able to mount hfs
filesystems.
* CVE-2011-4326: A bug was found in the way headroom
check was performed in udp6_ufo_fragment() function. A
remote attacker could use this flaw to crash the system.
The following non-security bugs have been fixed:
* ALSA: hda - Fix S3/S4 problem on machines with
VREF-pin mute-LED (bnc#732535).

(bnc#722429).

* pv-on-hvm/kexec: add xs_reset_watches to shutdown
watches from old kernel (bnc#694863).
* x86: undo_limit_pages() must reset page count.
* mm/vmstat.c: cache align vm_stat (bnc#729721).
* s390/ccwgroup: fix uevent vs dev attrs race
(bnc#659101,LTC#69028).
