 Mandriva Linux Security Advisory                         MDVSA-2015:125
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : tcpdump
 Date    : March 29, 2015
 Affected: Business Server 2.0
 _______________________________________________________________________

 Problem Description:

 Updated tcpdump package fixes security vulnerabilities:
 
 The Tcpdump program could crash when processing a malformed OLSR
 payload when the verbose output flag was set (CVE-2014-8767).
 
 The application decoder for the Ad hoc On-Demand Distance Vector (AODV)
 protocol in Tcpdump fails to perform input validation and performs
 unsafe out-of-bound accesses. The application will usually not crash,
 but perform out-of-bounds accesses and output/leak larger amounts of
 invalid data, which might lead to dropped packets. It is unknown if
 a payload exists that might trigger segfaults (CVE-2014-8769).
 
 It was discovered that tcpdump incorrectly handled printing PPP
 packets. A remote attacker could use this issue to cause tcpdump to
 crash, resulting in a denial of service, or possibly execute arbitrary
 code (CVE-2014-9140).
 
 Several vulnerabilities have been discovered in tcpdump. These
 vulnerabilities might result in denial of service (application
 crash) or, potentially, execution of arbitrary code (CVE-2015-0261,
 CVE-2015-2153, CVE-2015-2154, CVE-2015-2155).
