"tcpdump was updated to fix three security issues.

These security issues were fixed :

  - CVE-2014-8767: Integer underflow in the olsr_print
    function in tcpdump 3.9.6 through 4.6.2, when in verbose
    mode, allowed remote attackers to cause a denial of
    service (crash) via a crafted length value in an OLSR
    frame (bnc#905870 905871).

  - CVE-2014-8769: tcpdump 3.8 through 4.6.2 might allowed
    remote attackers to obtain sensitive information from
    memory or cause a denial of service (packet loss or
    segmentation fault) via a crafted Ad hoc On-Demand
    Distance Vector (AODV) packet, which triggers an
    out-of-bounds memory access (bnc#905871 905872).

  - CVE-2014-8768: Multiple Integer underflows in the
    geonet_print function in tcpdump 4.5.0 through 4.6.2,
    when in verbose mode, allowed remote attackers to cause
    a denial of service (segmentation fault and crash) via a
    crafted length value in a Geonet frame (bnc#905871)."
