INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack running Ubuntu 14.04
Trusty install these updates.
On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.
Alternatively, you can install these updates by running:
# /usr/sbin/uptrack-upgrade -y
DESCRIPTION
* Denial of service in ext4 extended attribute checksums.
A race condition in the ext4 filesystem driver can cause incorrect checksums to
be calculated for extended attributes which can allow a local user to cause a
denial of service.
* CVE-2017-5986: Denial-of-service when using SCTP socket with concurrent thread.
A BUG_ON() could be triggered when queueing data in a full SCTP socket
while another thread disassociates the first thread from the socket. A
local attacker could use this flaw to cause a denial-of-service.
* CVE-2017-6353: Denial-of-service when peeling off a sctp socket.
A logic error when peeling off a sctp socket could lead to a double free
or a deadlock. A local user could use this flaw to cause a
denial-of-service.
* Denial-of-service when bonding Infiniband interfaces.
A logic error when bonding IPoIB (IP over Infiniband) interfaces could
lead to a stack overflow. A local attacker with access to SIOCBONDENSLAVE
ioctl could use this flaw to cause a denial-of-service.
