The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4252-1 advisory.

    Multiple security issues were discovered in tcpdump. A remote attacker could use these issues to cause     tcpdump to crash, resulting in a denial of service, or possibly execute arbitrary code.

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.

This update for tcpdump fixes the following issues :

Security issues fixed :

CVE-2019-1010220: Fixed a buffer over-read in print_prefix() which may expose data (bsc#1142439).

CVE-2017-16808: Fixed a heap-based buffer over-read related to aoe_print() and lookup_emem() (bsc#1068716).

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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - tcpdump before 4.9.3 has a heap-based buffer over-read related to aoe_print in print-aoe.c and lookup_emem     in addrtoname.c. (CVE-2017-16808)
