RHEL 5 : bluez (Unpatched Vulnerability)

high Nessus Plugin ID 196425

Synopsis

The remote Red Hat 5 host is affected by multiple vulnerabilities that will not be patched.

Description

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

 - bluez: double free in gatttool client disconnect callback handler in src/shared/att.c could lead to DoS or RCE (CVE-2020-27153)

 - Buffer overflow in BlueZ 5.41 and earlier allows an attacker to execute arbitrary code via the parse_line function used in some userland utilities. (CVE-2016-7837)

 - 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.
 (CVE-2016-9797)

 - 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, 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. (CVE-2016-9803)

 - 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)

 - All versions of the SDP server in BlueZ 5.46 and earlier are vulnerable to an information disclosure vulnerability which allows remote attackers to obtain sensitive information from the bluetoothd process memory. This vulnerability lies in the processing of SDP search attribute requests. (CVE-2017-1000250)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
