Affected Products:

SLE 11 SERVER Unsupported Extras

______________________________________________________________________________

 

An update that fixes 22 vulnerabilities is now available.

It includes one version update.

 

Description:

 

 

The SUSE Linux Enterprise Server 11 SP1 LTSS received a roll up update to

fix several security and non-security issues.

 

The following security issues have been fixed:

 

* CVE-2013-1860: Heap-based buffer overflow in the wdm_in_callback

function in drivers/usb/class/cdc-wdm.c in the Linux kernel before

3.8.4 allows physically proximate attackers to cause a denial of

service (system crash) or possibly execute arbitrary code via a

crafted cdc-wdm USB device. (bnc#806431)

* CVE-2013-4162: The udp_v6_push_pending_frames function in

net/ipv6/udp.c in the IPv6 implementation in the Linux kernel

through 3.10.3 makes an incorrect function call for pending data,

which allows local users to cause a denial of service (BUG and

system crash) via a crafted application that uses the UDP_CORK

option in a setsockopt system call. (bnc#831058)

* CVE-2014-0203: The __do_follow_link function in fs/namei.c in the

Linux kernel before 2.6.33 does not properly handle the last

pathname component during use of certain filesystems, which allows

local users to cause a denial of service (incorrect free operations

and system crash) via an open system call. (bnc#883526)

* CVE-2014-3144: The (1) BPF_S_ANC_NLATTR and (2)

BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter

function in net/core/filter.c in the Linux kernel through 3.14.3 do

not check whether a certain length value is sufficiently large,

which allows local users to cause a denial of service (integer

underflow and system crash) via crafted BPF instructions. NOTE: the

affected code was moved to the __skb_get_nlattr and

__skb_get_nlattr_nest functions before the vulnerability was

announced. (bnc#877257)

* CVE-2014-3145: The BPF_S_ANC_NLATTR_NEST extension implementation in

the sk_run_filter function in net/core/filter.c in the Linux kernel

through 3.14.3 uses the reverse order in a certain subtraction,

which allows local users to cause a denial of service (over-read and

system crash) via crafted BPF instructions. NOTE: the affected code

was moved to the __skb_get_nlattr_nest function before the

vulnerability was announced. (bnc#877257)

* CVE-2014-3917: kernel/auditsc.c in the Linux kernel through 3.14.5,

when CONFIG_AUDITSYSCALL is enabled with certain syscall rules,

allows local users to obtain potentially sensitive single-bit values

from kernel memory or cause a denial of service (OOPS) via a large

value of a syscall number. (bnc#880484)

* CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux kernel

through 3.15.1 on 32-bit x86 platforms, when syscall auditing is

enabled and the sep CPU feature flag is set, allows local users to

cause a denial

of service (OOPS and system crash) via an invalid syscall number, as

demonstrated by number 1000. (bnc#883724)

* CVE-2014-4652: Race condition in the tlv handler functionality in

the snd_ctl_elem_user_tlv function in sound/core/control.c in the

ALSA control implementation in the Linux kernel before 3.15.2 allows

local users to obtain sensitive information from kernel memory by

leveraging /dev/snd/controlCX access. (bnc#883795)

* CVE-2014-4653: sound/core/control.c in the ALSA control

implementation in the Linux kernel before 3.15.2 does not ensure

possession of a read/write lock, which allows local users to cause a

denial of service (use-after-free) and obtain sensitive information

from kernel memory by leveraging /dev/snd/controlCX access.

(bnc#883795)

* CVE-2014-4654: The snd_ctl_elem_add function in sound/core/control.c

in the ALSA control implementation in the Linux kernel before 3.15.2

does not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE

commands, which allows local users to remove kernel controls and

cause a denial of service (use-after-free and system crash) by

leveraging /dev/snd/controlCX access for an ioctl call. (bnc#883795)

* CVE-2014-4655: The snd_ctl_elem_add function in sound/core/control.c

in the ALSA control implementation in the Linux kernel before 3.15.2

does not properly maintain the user_ctl_count value, which allows

local users to cause a denial of service (integer overflow and limit

bypass) by leveraging /dev/snd/controlCX access for a large number

of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls. (bnc#883795)

* CVE-2014-4656: Multiple integer overflows in sound/core/control.c in

the ALSA control implementation in the Linux kernel before 3.15.2

allow local users to cause a denial of service by leveraging

/dev/snd/controlCX access, related to (1) index values in the

snd_ctl_add function and (2) numid values in the

snd_ctl_remove_numid_conflict function. (bnc#883795)

* CVE-2014-4667: The sctp_association_free function in

net/sctp/associola.c in the Linux kernel before 3.15.2 does not

properly manage a certain backlog value, which allows remote

attackers to cause a denial of service (socket outage) via a crafted

SCTP packet. (bnc#885422)

* CVE-2014-4699: The Linux kernel before 3.15.4 on Intel processors

does not properly restrict use of a non-canonical value for the

saved RIP address in the case of a system call that does not use

IRET, which allows local users to leverage a race condition and gain

privileges, or cause a denial of service (double fault), via a

crafted application that makes ptrace and fork system calls.

(bnc#885725)

* CVE-2014-4943: The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the

Linux kernel through 3.15.6 allows local users to gain privileges by

leveraging data-structure differences between an l2tp socket and an

inet socket. (bnc#887082)

* CVE-2014-5077: The sctp_assoc_update function in

net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP

authentication is enabled, allows remote attackers to cause a denial

of service (NULL pointer dereference and OOPS) by starting to

establish an association between two endpoints immediately after an

exchange of INIT and INIT ACK chunks to establish an earlier

association between these endpoints in the opposite direction.

(bnc#889173)

* CVE-2013-7266: The mISDN_sock_recvmsg function in

drivers/isdn/mISDN/socket.c in the Linux kernel before 3.12.4 does

not ensure that a certain length value is consistent with the size

of an associated data structure, which allows local users to obtain

sensitive information from kernel memory via a (1) recvfrom, (2)

recvmmsg, or (3) recvmsg system call. (bnc#854722)

* CVE-2013-7267: The atalk_recvmsg function in net/appletalk/ddp.c in

the Linux kernel before 3.12.4 updates a certain length value

without ensuring that an associated data structure has been

initialized, which allows local users to obtain sensitive

information from kernel memory via a (1) recvfrom, (2) recvmmsg, or

(3) recvmsg system call. (bnc#854722)

* CVE-2013-7268: The ipx_recvmsg function in net/ipx/af_ipx.c in the

Linux kernel before 3.12.4 updates a certain length value without

ensuring that an associated data structure has been initialized,

which allows local users to obtain sensitive information from kernel

memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call.

(bnc#854722)

* CVE-2013-7269: The nr_recvmsg function in net/netrom/af_netrom.c in

the Linux kernel before 3.12.4 updates a certain length value

without ensuring that an associated data structure has been

initialized, which allows local users to obtain sensitive

information from kernel memory via a (1) recvfrom, (2) recvmmsg, or

(3) recvmsg system call. (bnc#854722)

* CVE-2013-7270: The packet_recvmsg function in net/packet/af_packet.c

in the Linux kernel before 3.12.4 updates a certain length value

before ensuring that an associated data structure has been

initialized, which allows local users to obtain sensitive

information from kernel memory via a (1) recvfrom, (2) recvmmsg, or

(3) recvmsg system call. (bnc#854722)

* CVE-2013-7271: The x25_recvmsg function in net/x25/af_x25.c in the

Linux kernel before 3.12.4 updates a certain length value without

ensuring that an associated data structure has been initialized,

which allows local users to obtain sensitive information from kernel

memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call.

(bnc#854722)

 

The following bugs have been fixed:

 

* mac80211: Fix AP powersave TX vs. wakeup race (bnc#871797).

* tcp: Allow to disable cwnd moderation in TCP_CA_Loss state

(bnc#879921).
