INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack running Oracle Enhanced
RHCK 7 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
* CVE-2017-14106: Divide-by-zero on TCP disconnect.
A missing initialization of the TCP Maximum Segment Size (MSS) to the
minimum authorized MSS value could lead to a division by zero on TCP
disconnect. A local user could use this flaw to cause a denial-of-service.
* CVE-2017-7184: Privilege escalation when using xfrm IP framework.
A missing check when using xfrm IP framework could lead to an out of
bound access. A local attacker could use this flaw to cause a denial of
service or to escalate privilege.
* CVE-2017-1000111: Privilege escalation when setting options on AF_PACKET socket.
A missing locking when setting options on AF_PACKET socket could lead to
an out-of-bounds access. A local attacker with CAP_NET_RAW capability,
or on a system with unprivileged namespace enabled, could use this flaw
to cause a denial-of-service or execute arbitrary code.
* CVE-2017-7558: Information disclosure in SCTP diagnostic reporting.
Incorrect sanitisation of information in the SCTP diagnostic information
reporting can result in uninitialised memory being provided to
userspace. A local user could use this flaw to facilitate a further
attack on the kernel.
* CVE-2017-7541: Buffer overflow in Broadcom IEEE802.11n embedded FullMAC WLAN driver.
A logic error in Broadcom IEEE802.11n embedded FullMAC WLAN driver could
lead to buffer overflow when user send a crafted NL80211_CMD_FRAME
packet via netlink. A local attacker could use this flaw to cause a
* CVE-2017-11176: Use-after-free in message queue notify syscall.
A race condition when closing a message queue file descriptor could
cause the memory for the associated socket to be freed twice, corrupting
memory or causing a denial-of-service.
* CVE-2017-7542: Buffer overflow when parsing IPV6 fragments header.
An incorrect data type when parsing IPV6 fragments header could lead to
a buffer overflow and to an infinite loop. A remote attacker could use
this flaw to cause a denial-of-service.
* CVE-2017-1000112: Privilege escalation using the UDP Fragmentation Offload (UFO) code.
Multiple missing checks on headers length when using UDP Fragmentation
Offload (UFO) protocol while sending packets could lead to out-of-bounds
accesses. A local attacker with CAP_NET_RAW capability, or on a system
with unprivileged namespace enabled, could use this flaw to cause a
denial-of-service or execute arbitrary code.
* CVE-2016-8399: Information leak using ICMP protocol.
A missing check on ICMP header length could cause an out-of-bounds read
of stack. A user could use this flaw to leak information about
kernel memory and facilitate an attack.
