-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2015:126 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ 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. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9680 http://advisories.mageia.org/MGASA-2015-0079.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 2/X86_64: 6ed0eae05d8850045a5e3195b19f1b86 mbs2/x86_64/sudo-1.8.12-1.mbs2.x86_64.rpm 28b150485a3212819aed04e3f9d57479 mbs2/x86_64/sudo-devel-1.8.12-1.mbs2.x86_64.rpm aff8ffe7a8374c94f38058b5464d7e5c mbs2/SRPMS/sudo-1.8.12-1.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
