EulerOS Virtualization 3.0.2.6 : bluez (EulerOS-SA-2021-1427)

high Nessus Plugin ID 147516

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

 - 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 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)
