"Updated sudo packages fix security vulnerability :

Prior to sudo 1.8.12, the TZ environment variable was passed through
unchecked. Most libc tzset() implementations support passing an
absolute pathname in the time zone to point to an arbitrary,
user-controlled file. This may be used to exploit bugs in the C
library's TZ parser or open files the user would not otherwise have
access to. Arbitrary file access via TZ could also be used in a denial
of service attack by reading from a file or fifo that will block
(CVE-2014-9680).

The sudo package has been updated to version 1.8.12, fixing this issue
and several other bugs."
