Mandriva Linux Security Advisory 2015-125 - The Tcpdump program could crash when processing a malformed OLSR payload when the verbose output flag was set. The application decoder for the Ad hoc On-Demand Distance Vector 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. 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. Several vulnerabilities have been discovered in tcpdump. These vulnerabilities might result in denial of service (application crash) or, potentially, execution of arbitrary code. .

Mandriva Linux Security Advisory MDVSA-2015:125

_______________________________________________________________________
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).
