Descriptions
The RTCP parser in tcpdump before 4.9.0 has a buffer overflow in print-udp.c:rtcp_print().
El analizador RTCP en tcpdump en versiones anteriores a 4.9.0 tiene un desbordamiento de búfer en print-udp.c:rtcp_print().
Multiple out of bounds read and integer overflow vulnerabilities were found in tcpdump affecting the decoding of various protocols. An attacker could create a crafted pcap file or send specially crafted packets to the network segment where tcpdump is running in live capture mode (without -w) which could cause it to display incorrect data, crash or enter an infinite loop.
The tcpdump packages contain the tcpdump utility for monitoring network traffic. The tcpdump utility can capture and display the packet headers on a particular network interface or on all interfaces. The following packages have been upgraded to a later upstream version: tcpdump. Security Fix: Multiple out of bounds read and integer overflow vulnerabilities were found in tcpdump affecting the decoding of various protocols. An attacker could create a crafted pcap file or send specially crafted packets to the network segment where tcpdump is running in live capture mode which could cause it to display incorrect data, crash or enter an infinite loop.
