SuSE 11.3 Security Update : Linux kernel (SAT Patch Numbers 9102 / 9104 / 9105)

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote SuSE 11 host is missing one or more security updates.

Description :

The SUSE Linux Enterprise 11 Service Pack 3 kernel has been updated to
fix various bugs and security issues.

----------------------------------------------------------------------
- WARNING: If you are running KVM with PCI pass-through on a system
with one of the following Intel chipsets: 5500 (revision 0x13), 5520
(revision 0x13) or X58 (revisions 0x12, 0x13, 0x22), please make sure
to read the following support document before installing this update :

https://www.suse.com/support/kb/doc.php?id=7014344

You will have to update your KVM setup to no longer make use of PCI
pass-through before rebooting to the updated kernel.

----------------------------------------------------------------------
-

The following security bugs have been fixed :

- The Linux kernel before 3.12, when UDP Fragmentation
Offload (UFO) is enabled, does not properly initialize
certain data structures, which allows local users to
cause a denial of service (memory corruption and system
crash) or possibly gain privileges via a crafted
application that uses the UDP_CORK option in a
setsockopt system call and sends both short and long
packets, related to the ip_ufo_append_data function in
net/ipv4/ip_output.c and the ip6_ufo_append_data
function in net/ipv6/ip6_output.c. (bnc#847672).
(CVE-2013-4470)

- The microcode on AMD 16h 00h through 0Fh processors does
not properly handle the interaction between locked
instructions and write-combined memory types, which
allows local users to cause a denial of service (system
hang) via a crafted application, aka the errata 793
issue. (bnc#852967). (CVE-2013-6885)

- The Linux kernel before 3.12.4 updates certain length
values before ensuring that associated data structures
have been initialized, which allows local users to
obtain sensitive information from kernel stack memory
via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system
call, related to net/ipv4/ping.c, net/ipv4/raw.c,
net/ipv4/udp.c, net/ipv6/raw.c, and net/ipv6/udp.c.
(bnc#857643). (CVE-2013-7263)

- The l2tp_ip_recvmsg function in net/l2tp/l2tp_ip.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 stack memory via a (1)
recvfrom, (2) recvmmsg, or (3) recvmsg system call.
(bnc#857643). (CVE-2013-7264)

- The pn_recvmsg function in net/phonet/datagram.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 stack memory via a (1)
recvfrom, (2) recvmmsg, or (3) recvmsg system call.
(bnc#857643). (CVE-2013-7265)

- The cifs_iovec_write function in fs/cifs/file.c in the
Linux kernel through 3.13.5 does not properly handle
uncached write operations that copy fewer than the
requested number of bytes, which allows local users to
obtain sensitive information from kernel memory, cause a
denial of service (memory corruption and system crash),
or possibly gain privileges via a writev system call
with a crafted pointer. (bnc#864025). (CVE-2014-0069)
