Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2016-9798)
The vulnerability allows a local user to perform denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the conf_opt() function in tools/parser/l2cap.c when processing a corrupted dump file. A local user can use a specially crafted dump file to crash hcidump.
2) Out-of-bounds read (CVE-ID: CVE-2016-9918)
The vulnerability allows a local user to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within packet_hexdump() function in monitor/packet.c. A local user can pass a specially crafted dump file, trigger out-of-bounds read error and crash the affected application.
3) Buffer overflow (CVE-ID: CVE-2016-9917)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the read_n() function in tools/hcidump.c. A local user can pass a specially crafted dump file, trigger a buffer overflow and crash hcidump.4) Buffer overflow (CVE-ID: CVE-2016-9804)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the commands_dump() function in tools/parser/csr.c. A local user can pass a specially crafted dump file, trigger a buffer overflow and crash hcidump.5) Out-of-bounds read (CVE-ID: CVE-2016-9918)
The vulnerability allows a local user to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the "packet_hexdump()" function in monitor/packet.c. A local user can pass a specially crafted dump file, trigger a buffer overflow and crash hcidump.
6) Out-of-bounds read (CVE-ID: CVE-2016-9803)
The vulnerability allows a local user to perform a denial of service attack.
The vulnerability exists due to a boundary condition within the le_meta_ev_dump() function in tools/parser/hci.c. A local user can pass a specially crafted dump file, trigger a buffer overflow and crash application.
7) Buffer overflow (CVE-ID: CVE-2016-9801)
The vulnerability allows a local user to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the set_ext_ctrl() function in tools/parser/l2cap.c. A local user can pass a specially crafted dump file, trigger a buffer overflow and crash application.
8) Buffer overflow (CVE-ID: CVE-2016-9800)
The vulnerability allows a local user to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the pin_code_reply_dump() function in tools/parser/hci.c. A local user can pass a specially crafted dump file, trigger a buffer overflow and crash application.
9) Buffer overflow (CVE-ID: CVE-2016-9799)
The vulnerability allows a local user to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the pklg_read_hci() function in btsnoop.c. A local user can pass a specially crafted dump file, trigger a buffer overflow and crash application.
