SUSE Linux Enterprise Desktop 11 SP1

______________________________________________________________________________

 

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:
