Mandriva Linux Security Advisory 2015-126 - 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. The sudo package has been updated to version 1.8.12, fixing this issue and several other bugs.

Package : sudo
Date : March 29, 2015
Affected: Business Server 2.0

Problem Description:
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.
