Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow via the do_checksum_math_liveplay() function in the tcpliveplay utility. An attacker can cause the application to crash or behave unexpectedly by submitting a specially crafted pcap file that triggers improper memory handling during checksum calculation.
Note:
According to the maintainer, tcpliveplay utility is going to be deprecated in version 4.6.
