Affected: AlmaLinux:9: bluez, AlmaLinux:9: bluez-cups, AlmaLinux:9: bluez-libs, AlmaLinux:9: bluez-libs-devel, AlmaLinux:9: bluez-obexd

The bluez packages contain the following utilities for use in Bluetooth applications: hcitool, hciattach, hciconfig, bluetoothd, l2ping, start scripts (AlmaLinux), and pcmcia configuration files.

Security Fix(es):

* bluez: unauthorized HID device connections allows keystroke injection and arbitrary commands execution (CVE-2023-45866) * BlueZ: Audio Profile AVRCP Improper Validation of Array Index Remote Code Execution Vulnerability (CVE-2023-27349) * bluez: phone book access profile heap-based buffer overflow remote code execution vulnerability (CVE-2023-51596) * bluez: OBEX library out-of-bounds read information disclosure vulnerability (CVE-2023-51594) * bluez: audio profile avrcp parse_media_folder out-of-bounds read information disclosure vulnerability (CVE-2023-51592) * bluez: audio profile avrcp parse_media_element out-of-bounds read information disclosure vulnerability (CVE-2023-51589) * bluez: avrcp_parse_attribute_list out-of-bounds read information disclosure vulnerability (CVE-2023-51580) * bluez: AVRCP stack-based buffer overflow remote code execution vulnerability (CVE-2023-44431) * bluez: phone book access profile heap-based buffer overflow remote code execution vulnerability (CVE-2023-50230) * bluez: phone book access profile heap-based buffer overflow remote code execution vulnerability (CVE-2023-50229)

BlueZ OBEX Library Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of BlueZ. User interaction is required to exploit this vulnerability in that the target must connect to a malicious Bluetooth device.

The specific flaw exists within the handling of OBEX protocol parameters. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-20937.
