tcpdump: Multiple vulnerabilities — GLSA 201502-05

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

Affected Packages

net-analyzer/tcpdump on all architectures
Affected versions < 4.6.2-r1
Unaffected versions >= 4.6.2-r1

Background

tcpdump is a tool for capturing and inspecting network traffic.

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"
