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.

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.

In BlueZ 5.42, an out-of-bounds read was observed in "le_meta_ev_dump" function in "tools/parser/hci.c" source file. This issue exists because 'subevent' (which is used to read correct element from 'ev_le_meta_str' array) is overflowed.

In BlueZ 5.42, a buffer overflow was observed in "pklg_read_hci" function in "btsnoop.c" source file. This issue can be triggered by processing a corrupted dump file and will result in btmon crash.

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.

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.

In BlueZ 5.42, a use-after-free was identified in "conf_opt" function in "tools/parser/l2cap.c" source file. This issue can be triggered by processing a corrupted dump file and will result in hcidump crash.

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.

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.

In BlueZ 5.42, a buffer over-read was observed in "l2cap_dump" function in "tools/parser/l2cap.c" source file. This issue can be triggered by processing a corrupted dump file and will result in hcidump crash.
