Several vulnerabilities have been discovered in tcpdump, a command-line network traffic analyzer. These security vulnerabilities might result in denial of service or, potentially, execution of arbitrary code.
For Debian 7 Wheezy, these problems have been fixed in version 4.9.3-1~deb7u1.
We recommend that you upgrade your tcpdump packages.
