In BlueZ 5.42, a buffer overflow was observed in 'pin_code_reply_dump' function in 'tools/parser/hci.c' source file. The issue exists because 'pin' array is overflowed by supplied parameter due to lack of boundary checks on size of the buffer from frame 'pin_code_reply_cp *cp' parameter.(CVE-2016-9800)

In BlueZ 5.42, a buffer overflow was observed in 'set_ext_ctrl' function in 'tools/parser/l2cap.c' source file when processing corrupted dump file.(CVE-2016-9801)

In BlueZ 5.42, a buffer over-read was identified in 'l2cap_packet' function in 'monitor/packet.c' source file. This issue can be triggered by processing a corrupted dump file and will result in btmon crash.(CVE-2016-9802)

In BlueZ 5.42, a buffer overflow was observed in 'commands_dump' function in 'tools/parser/csr.c' source file. The issue exists because 'commands' array is overflowed by supplied parameter due to lack of boundary checks on size of the buffer from frame 'frm->ptr' parameter. This issue can be triggered by processing a corrupted dump file and will result in hcidump crash.(CVE-2016-9804)

In BlueZ 5.42, a buffer overflow was observed in 'read_n' function in 'tools/hcidump.c' source file. This issue can be triggered by processing a corrupted dump file and will result in hcidump crash.(CVE-2016-9917)

In BlueZ 5.42, an out-of-bounds read was identified in 'packet_hexdump' function in 'monitor/packet.c' source file. This issue can be triggered by processing a corrupted dump file and will result in btmon crash.(CVE-2016-9918)");
