Affected Products:

openSUSE 11.3

______________________________________________________________________________

 

An update that solves 11 vulnerabilities and has two fixes

is now available. It includes one version update.

 

Description:

 

The openSUSE 11.3 kernel was updated to fix various bugs

and security issues.

 

Following security issues have been fixed: CVE-2011-4604:

If root does read() on a specific socket, it's possible to

corrupt (kernel) memory over network, with an ICMP packet,

if the B.A.T.M.A.N. mesh protocol is used.

 

CVE-2011-2525: A flaw allowed the tc_fill_qdisc() function

in the Linux kernels packet scheduler API implementation to

be called on built-in qdisc structures. A local,

unprivileged user could have used this flaw to trigger a

NULL pointer dereference, resulting in a denial of service.

 

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-2011-2213: The inet_diag_bc_audit function in

net/ipv4/inet_diag.c in the Linux kernel did not properly

audit INET_DIAG bytecode, which allowed local users to

cause a denial of service (kernel infinite loop) via

crafted INET_DIAG_REQ_BYTECODE instructions in a netlink

message, as demonstrated by an INET_DIAG_BC_JMP instruction

with a zero yes value, a different vulnerability than

CVE-2010-3880.

 

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-2011-2534: Buffer overflow in the clusterip_proc_write

function in net/ipv4/netfilter/ipt_CLUSTERIP.c in the Linux

kernel might have allowed local users to cause a denial of

service or have unspecified other impact via a crafted

write operation, related to string data that lacks a

terminating '\0' character.

 

CVE-2011-1770: Integer underflow in the dccp_parse_options

function (net/dccp/options.c) in the Linux kernel allowed

remote attackers to cause a denial of service via a

Datagram Congestion Control Protocol (DCCP) packet with an

invalid feature options length, which triggered a buffer

over-read.

 

CVE-2011-2723: The skb_gro_header_slow function in

include/linux/netdevice.h in the Linux kernel, when Generic

Receive Offload (GRO) is enabled, reset certain fields in

incorrect situations, which allowed remote attackers to

cause a denial of service (system crash) via crafted

network traffic.

 

CVE-2011-2898: A kernel information leak in the AF_PACKET

protocol was fixed which might have allowed local attackers

to read kernel memory.

 

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-2011-4081: Using the crypto interface a local user

could Oops the kernel by writing to a AF_ALG socket.

 

 

Special Instructions and Notes:

 

Please reboot the system after installing this update.

 

Patch Instructions:
