Mandriva Linux Security Advisory MDVSA-2014:244
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : openafs
Date : December 14, 2014
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been found and corrected in openafs:

Buffer overflow in certain client utilities in OpenAFS before 1.6.2
allows remote authenticated users to cause a denial of service (crash)
and possibly execute arbitrary code via a long fileserver ACL entry
(CVE-2013-1794).

Integer overflow in ptserver in OpenAFS before 1.6.2 allows remote
attackers to cause a denial of service (crash) via a large list
from the IdToName RPC, which triggers a heap-based buffer overflow
(CVE-2013-1795).

OpenAFS before 1.4.15, 1.6.x before 1.6.5, and 1.7.x before 1.7.26
uses weak encryption (DES) for Kerberos keys, which makes it easier
for remote attackers to obtain the service key (CVE-2013-4134).

The vos command in OpenAFS 1.6.x before 1.6.5, when using the -encrypt
option, only enables integrity protection and sends data in cleartext,
which allows remote attackers to obtain sensitive information by
sniffing the network (CVE-2013-4135).

Buffer overflow in the GetStatistics64 remote procedure call (RPC) in
OpenAFS 1.4.8 before 1.6.7 allows remote attackers to cause a denial
of service (crash) via a crafted statsVersion argument (CVE-2014-0159).

A denial of service flaw was found in libxml2, a library providing
support to read, modify and write XML and HTML files. A remote attacker
could provide a specially crafted XML file that, when processed by
an application using libxml2, would lead to excessive CPU consumption
(denial of service) based on excessive entity substitutions, even if
entity substitution was disabled, which is the parser default behavior
(CVE-2014-3660).

The updated packages have been upgraded to the 1.4.15 version and
patched to correct these issues.
