Description
The command-line argument parser in tcpdump before 4.9.3 has a buffer overflow in tcpdump.c:get_next_file().
An out-of-bounds write vulnerability was discovered in tcpdump while reading the file passed to the -V option of the command line program. An attacker may abuse this flaw by tricking a victim user into using a malicious file with the -V option, which would make the program read one byte before a stack-based allocated buffer and potentially write a NULL byte to it.
