INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack on EL 5 install these
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-2014-3688: Remote denial-of-service in SCTP stack by memory exhaustion.
A flaw in the SCTP stack could allow a remote attacker to force a SCTP
server to allocate big amounts of memory and trigger the kernel
out-of-memory killer, leading to a denial-of-service.
* CVE-2014-4656: ALSA Control ID overflow.
Missing range checks in ALSA control IDs could lead to an integer overflow.
* CVE-2014-6410: Denial of service in UDF filesystem parsing.
The kernel UDF filesystem driver does not correctly validate indirect
inodes allowing a malicious user to cause a kernel panic by mounting a
UDF volume with deeply nested indirect inodes.
* Improved fix to CVE-2014-3184: Invalid memory write in HID drivers.
The original fix for CVE-2014-3184 did not include all vulnerable
drivers. A local user with physical access to the system could use this
flaw to write past an allocated memory buffer.
* CVE-2014-4652: Arbitrary memory disclosure in ALSA user controls.
Lack of synchronization between reads and writes to ALSA user controls
could lead to a kernel memory disclosure.
