The FRF.15 parser in tcpdump before 4.9.0 has a buffer overflow in print-fr.c:frf15_print().

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - tcpdump: multiple overflow issues in protocol decoding (CVE-2017-5486)

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

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

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - tcpdump: multiple overflow issues in protocol decoding (CVE-2017-5486)

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

  - tcpdump 3.8 through 4.6.2 might allow 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. (CVE-2014-8769)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

An update of the tcpdump package has been released.

CVE-2016-7992 The Classical IP over ATM parser in tcpdump before 4.9.0 has a buffer overflow in print-cip.c:cip_if_print().

CVE-2016-7993 A bug in util-print.c:relts_print() in tcpdump before 4.9.0 could cause a buffer overflow in multiple protocol parsers (DNS, DVMRP, HSRP, IGMP, lightweight resolver protocol, PIM).

CVE-2016-8574 The FRF.15 parser in tcpdump before 4.9.0 has a buffer overflow in print-fr.c:frf15_print().

CVE-2016-8575 The Q.933 parser in tcpdump before 4.9.0 has a buffer overflow in print-fr.c:q933_print(), a different vulnerability than CVE-2017-5482.

Impact

An attacker can gain access to sensitive information. An attacker can also cause a denial of service (DoS) by way of a crafted pcap file or by sending specially crafted packets to the network segment where tcpdump is actively capturing network traffic. The tcpdump program does not use the protocol decoding subsystem and is therefore not affected by these vulnerabilities when using the -w option to write raw packets to a pcap file for offline examination.

According to the versions of the tcpdump package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Multiple out of bounds read and integer overflow     vulnerabilities were found in tcpdump affecting the     decoding of various protocols. An attacker could create     a crafted pcap file or send specially crafted packets     to the network segment where tcpdump is running in live     capture mode (without -w) which could cause it to     display incorrect data, crash or enter an infinite     loop.

An update for tcpdump is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The tcpdump packages contain the tcpdump utility for monitoring network traffic. The tcpdump utility can capture and display the packet headers on a particular network interface or on all interfaces.

The following packages have been upgraded to a later upstream version:
tcpdump (4.9.0). (BZ#1422473)

Security Fix(es) :

* Multiple out of bounds read and integer overflow vulnerabilities were found in tcpdump affecting the decoding of various protocols.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3205-1 advisory.

    It was discovered that tcpdump incorrectly handled certain packets. A remote attacker could use this issue     to cause tcpdump to crash, resulting in a denial of service, or possibly execute arbitrary code.

    In the default installation, attackers would be isolated by the tcpdump AppArmor profile.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote host is affected by the vulnerability described in GLSA-201702-30 (tcpdump: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in tcpdump. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker, by sending a specially crafted network package, could       possibly execute arbitrary code with the privileges of the process or       cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.
