Oracle VM Security Advisory OVMSA-2009-0004

The following updated rpms for Oracle VM 2.1 have been uploaded to the 
Unbreakable Linux Network:



Description of changes:

Following Security fixes are released in this errata:

CVE-2008-3528 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3528>
The error-reporting functionality in (1) fs/ext2/dir.c, (2) 
fs/ext3/dir.c, and possibly (3) fs/ext4/dir.c in the Linux kernel does not limit the number of printk console messages that 
report directory corruption, which allows physically proximate attackers 
to cause a denial of service (temporary system hang) by mounting a 
filesystem that has corrupted dir->i_size and dir->i_blocks values and 
performing (a) read or (b) write operations. NOTE: there are limited 
scenarios in which this crosses privilege boundaries.

CVE-2008-5700 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5700>
libata in the Linux kernel before does not set minimum timeouts 
for SG_IO requests, which allows local users to cause a denial of 
service (Programmed I/O mode on drives) via multiple simultaneous 
invocations of an unspecified test program.

CVE-2009-0028 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0028>
The clone system call in the Linux kernel 2.6.28 and earlier allows 
local users to send arbitrary signals to a parent process from an 
unprivileged child process by launching an additional child process with 
the CLONE_PARENT flag, and then letting this new process exit.
CVE-2009-0322 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0322>
drivers/firmware/dell_rbu.c in the Linux kernel before, and 
2.6.28.x before, allows local users to cause a denial of 
service (system crash) via a read system call that specifies zero bytes 
from the (1) image_type or (2) packet_size file in 
CVE-2009-0675 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0675>
The skfp_ioctl function in drivers/net/skfp/skfddi.c in the Linux kernel 
before permits SKFP_CLR_STATS requests only when the 
CAP_NET_ADMIN capability is absent, instead of when this capability is 
present, which allows local users to reset the driver statistics, 
related to an "inverted logic" issue.
CVE-2009-0676 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0676>
The sock_getsockopt function in net/core/sock.c in the Linux kernel 
before does not initialize a certain structure member, which 
allows local users to obtain potentially sensitive information from 
kernel memory via an SO_BSDCOMPAT getsockopt request.
