tcpdump.org tcpdump 4.9.2 is affected by: CWE-126: Buffer Over-read. The impact is: May expose Saved Frame Pointer, Return Address etc. on stack. The component is: line 234: "ND_PRINT((ndo, "%s", buf));", in function named "print_prefix", in "print-hncp.c". The attack vector is: The victim must open a specially crafted pcap file.

In tcpdump 4.9.2, a stack-based buffer over-read exists in the print_prefix function of print-hncp.c via crafted packet data because of missing initialization.

tcpdump before 4.9.3 has a heap-based buffer over-read related to aoe_print in print-aoe.c and lookup_emem in addrtoname.c.

print-wb.c in tcpdump before 4.7.4 allows remote attackers to cause a denial of service (segmentation fault and process crash).

The ISO IS-IS parser in tcpdump before 4.9.2 has a buffer over-read in print-isoclns.c:isis_print_is_reach_subtlv().

The BOOTP parser in tcpdump before 4.9.2 has a buffer over-read in print-bootp.c:bootp_print().

The PIMv2 parser in tcpdump before 4.9.2 has a buffer over-read in print-pim.c:pimv2_print().
