CVE-2018-16301

Estado: ModificadaAlta (7.8)—

The command-line argument parser in tcpdump before 4.99.0 has a buffer overflow in tcpdump.c:read_infile(). To trigger this vulnerability the attacker needs to create a 4GB file on the local filesystem and to specify the file name as the value of the -F command-line argument of tcpdump.
