Suleiman Souhlal, Salman Qazi, Aaron Durbin and Michael Davidson discovered
a race condition in the Linux kernel's ptrace syscall. An unprivileged
local attacker could exploit this flaw to run programs as an administrator.

A flaw was discovered in the Edgeort USB serial converter driver when the
device is disconnected while it is in use. A local user could exploit this
flaw to cause a denial of service (system crash). (CVE-2013-1774)

A flaw was discovered in the ChipIdea Highspeed Dual Role and ChipIdea host
controller drivers in the Linux kernel. A local user could use this flaw to
cause a denial of service (system crash). (CVE-2013-2058)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.10

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.
