Mandriva Linux Security Advisory : tcpdump (MDVSA-2014:240)

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing a security update.

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).
