Mandriva Linux Security Advisory MDVSA-2014:240
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

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

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).
