Tcpdump · Tcpdump · CVE-2015-2153
**Name of the Vulnerable Software and Affected Versions**
tcpdump versions prior to 4.7.2
**Description**
The issue allows remote attackers to cause a denial of service, resulting in an out-of-bounds read or write and crash, via a crafted header length in an RPKI-RTR Protocol Data Unit (PDU). This is due to a problem in the `rpki rtr pdu print` function.
**Recommendations**
For versions prior to 4.7.2, update to version 4.7.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the `rpki rtr pdu print` function until a patch is available.
