The osi_print_cksum function in print-isoclns.c in the ethernet printer in tcpdump before 4.7.2 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted (1) length, (2) offset, or (3) base pointer checksum value.

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.

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) :

The remote host is affected by the vulnerability described in GLSA-201510-04 (tcpdump: Multiple vulnerabilities)

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

    A remote attacker 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.

Integer signedness error in the mobility_opt_print function in the IPv6 mobility printer in tcpdump before 4.7.2 allows remote attackers to cause a denial of service (out-of-bounds read and crash) or possibly execute arbitrary code via a negative length value.
(CVE-2015-0261)

The osi_print_cksum function in print-isoclns.c in the ethernet printer in tcpdump before 4.7.2 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted (1) length, (2) offset, or (3) base pointer checksum value.
(CVE-2015-2154)

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2580-1 advisory.

    It was discovered that tcpdump incorrectly handled printing 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.

Contains security fix for CVE-2015-0261, CVE-2015-2154, CVE-2015-2153, CVE-2015-2155.

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

When running tcpdump, a remote unauthenticated user could have crashed the application or, potentially, execute arbitrary code by injecting crafted packages into the network.

The following vulnerabilities in protocol printers have been fixed :

  - IPv6 mobility printer remote DoS. (CVE-2015-0261,     bnc#922220)

  - Ethernet printer remote DoS. (CVE-2015-2154, bnc#922222)

  - PPP printer remote DoS (CVE-2014-9140, bnc#923142)

Rebase to 4.7.3 (#1201573). Contains security fix for CVE-2015-0261, CVE-2015-2154, CVE-2015-2153, CVE-2015-2155.

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

Updated tcpdump package fixes security vulnerabilities :

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).

tcpdump was updated to fix five vulnerabilities in protocol printers

When running tcpdump, a remote unauthenticated user could have crashed the application or, potentially, execute arbitrary code by injecting crafted packages into the network.

The following vulnerabilities were fixed :

  - IPv6 mobility printer remote DoS (CVE-2015-0261,     bnc#922220)

  - PPP printer remote DoS (CVE-2014-9140, bnc#923142)

  - force printer remote DoS (CVE-2015-2155, bnc#922223)

  - ethernet printer remote DoS (CVE-2015-2154, bnc#922222)

  - tcp printer remote DoS (CVE-2015-2153, bnc#922221)

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).

Several issues have been discovered with tcpdump in the way it handled some printer protocols. Those issues can lead to denial of service, or, potentially, execution of arbitrary code.

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

Several vulnerabilities have been discovered in tcpdump, a command-line network traffic analyzer. These vulnerabilities might result in denial of service (application crash) or, potentially, execution of arbitrary code.
