http://security.gentoo.org/

Severity:	normal
Title:	tcpdump: Multiple vulnerabilities
Date:	02/07/2015
Bugs:	#534660
ID:	201502-05

Synopsis

Multiple vulnerabilities in tcpdump could result in execution of arbitrary code or Denial of Service.

Background

tcpdump is a tool for capturing and inspecting network traffic.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-analyzer/tcpdump	< 4.6.2-r1	>= 4.6.2-r1	All supported architectures

Description

Multiple vulnerabilities have been discovered in tcpdump:

The olsr_print function function contains an integer underflow error (CVE-2014-8767)
The geonet_print function function contains multiple integer underflow errors (CVE-2014-8768)
The decoder for the Ad hoc On-Demand Distance Vector protocol contains an out-of-bounds memory access error (CVE-2014-8769)
The ppp_hdlc function contains a buffer overflow error (CVE-2014-9140)

Impact

A remote attacker may be able to send a specially crafted packet, possibly resulting in execution of arbitrary code or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All tcpdump users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-analyzer/tcpdump-4.6.2-r1"
