Description

This security bulletin contains information about 9 vulnerabilities.

1) Use-after-free (CVE-ID: CVE-2016-9798)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

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)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

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)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

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)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

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)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

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.

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)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

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)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

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.
