EulerOS Virtualization for ARM 64 3.0.2.0 : bluez (EulerOS-SA-2021-2088)

high Nessus Plugin ID 151295

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.

Description

According to the versions of the bluez package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

- 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)

- 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, 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 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 '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 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 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.(CVE-2016-9798)

- In BlueZ before 5.55, a double free was found in the gatttool disconnect_cb() routine from shared/att.c. A remote attacker could potentially cause a denial of service or code execution, during service discovery, due to a redundant disconnect MGMT event.(CVE-2020-27153)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected bluez packages.
