Releases
Packages
- linux-ti-omap4 - Linux kernel for OMAP4
Details
Kees Cook discovered a flaw in the Linux kernel's iSCSI subsystem. A remote
unauthenticated attacker could exploit this flaw to cause a denial of
service (system crash) or potentially gain administrative privileges.
(CVE-2013-2850)
An information leak was discovered in the Linux kernel when inotify is used
to monitor the /dev/ptmx device. A local user could exploit this flaw to
discover keystroke timing and potentially discover sensitive information
like password length. (CVE-2013-0160)
A flaw was discovered in the Linux kernel's perf events subsystem for Intel
Sandy Bridge and Ivy Bridge processors. A local user could exploit this
flaw to cause a denial of service (system crash). (CVE-2013-2146)
An information leak was discovered in the Linux kernel's crypto API. A
local user could exploit this flaw to examine potentially sensitive
information from the kernel's stack memory. (CVE-2013-3076)
An information leak was discovered in the Linux kernel's rcvmsg path for
ATM (Asynchronous Transfer Mode). A local user could exploit this flaw to
examine potentially sensitive information from the kernel's stack memory.
(CVE-2013-3222)
An information leak was discovered in the Linux kernel's recvmsg path for
ax25 address family. A local user could exploit this flaw to examine
potentially sensitive information from the kernel's stack memory.
(CVE-2013-3223)
An information leak was discovered in the Linux kernel's recvmsg path for
the bluetooth address family. A local user could exploit this flaw to
examine potentially sensitive information from the kernel's stack memory.
(CVE-2013-3224)
An information leak was discovered in the Linux kernel's bluetooth rfcomm
protocol support. A local user could exploit this flaw to examine
potentially sensitive information from the kernel's stack memory.
(CVE-2013-3225)
An information leak was discovered in the Linux kernel's CAIF protocol
implementation. A local user could exploit this flaw to examine potentially
sensitive information from the kernel's stack memory. (CVE-2013-3227)
An information leak was discovered in the Linux kernel's IRDA (infrared)
support subsystem. A local user could exploit this flaw to examine
potentially sensitive information from the kernel's stack memory.
(CVE-2013-3228)
An information leak was discovered in the Linux kernel's s390 - z/VM
support. A local user could exploit this flaw to examine potentially
sensitive information from the kernel's stack memory. (CVE-2013-3229)
An information leak was discovered in the Linux kernel's llc (Logical Link
Layer 2) support. A local user could exploit this flaw to examine
potentially sensitive information from the kernel's stack memory.
(CVE-2013-3231)
An information leak was discovered in the Linux kernel's receive message
handling for the netrom address family. A local user could exploit this
flaw to obtain sensitive information from the kernel's stack memory.
(CVE-2013-3232)
An information leak was discovered in the Linux kernel's Rose X.25 protocol
layer. A local user could exploit this flaw to examine potentially
sensitive information from the kernel's stack memory. (CVE-2013-3234)
An information leak was discovered in the Linux kernel's TIPC (Transparent
Inter Process Communication) protocol implementation. A local user could
exploit this flaw to examine potentially sensitive information from the
kernel's stack memory. (CVE-2013-3235)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
