We recommend that all users of Ksplice Uptrack on Debian 7.0 Wheezy
install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2014-7825, CVE-2014-7826: Perf DoS and local privilege escalation.

A missing validation of syscall id range allows an attacker to trigger a
kernel panic, or leverage it into gaining root privileges if root was
doing perf tracing at that time.


* CVE-2014-8369: Denial-of-service in KVM page mapping.

Due to an incomplete fix for CVE-2014-3601, the KVM map pages function
miscalculates the number of pages to be un-pinned in case of a mapping
failure, which allows guest OS users to cause a denial-of-service by
corrupting the host memory.


* CVE-2014-7841: NULL pointer dereference with SCTP server during ASCONF.

A problem with how the SCTP verifies input can lead to a NULL pointer
dereference and kernel panic.  A malicious user could exploit this using
a specially crafted packet to cause a denial-of-service.


* CVE-2014-8884: Buffer overflow in DEC2000 and DEC3000 USB adapters.

A lack of input validation when copying an ioctl command could lead to
overflowing data on the stack, causing a kernel panic. A local user could
use this flaw to cause a denial-of-service or potentially escalate
privileges.


* CVE-2014-9090: Denial-of-service in double-fault handling on bad stack segment.

A flaw when handling double faults associated with the stack segment
register could lead to a kernel panic.  A local, unprivileged user could
use this flaw via the modify_ldt() system call to cause a
denial-of-service.
