It was discovered that tcpdump before 4.99.4 contained an out-of-bounds write in the SMB printer (smbutil.c). The code incorrectly assumed that the format printed representation of the tm_year variable would always fit into 4 characters, which was not enough. This could lead to stack buffer overflow in some cases.
