Ubuntu 14.04 LTS : tcpdump vulnerabilities (USN-2433-1)

critical Nessus Plugin ID 79741

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2433-1 advisory.

 Steffen Bauch discovered that tcpdump incorrectly handled printing OSLR 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-2014-8767)

 Steffen Bauch discovered that tcpdump incorrectly handled printing GeoNet packets. A remote attacker could use this issue to cause tcpdump to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only applied to Ubuntu 14.04 LTS and Ubuntu 14.10. (CVE-2014-8768)

 Steffen Bauch discovered that tcpdump incorrectly handled printing AODV packets. A remote attacker could use this issue to cause tcpdump to crash, resulting in a denial of service, reveal sensitive information, or possibly execute arbitrary code. (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)

 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.

Solution

Update the affected tcpdump package.
