Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.63%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

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.
