Several vulnerabilities have been discovered in tcpdump, a command-line
network traffic analyzer. These vulnerabilities might result in denial
of service, leaking sensitive information from memory or, potentially,
execution of arbitrary code.
For the stable distribution (wheezy), these problems have been fixed in
version 4.3.0-1+deb7u1.
For the upcoming stable distribution (jessie), these problems have been
fixed in version 4.6.2-3.
For the unstable distribution (sid), these problems have been fixed in
