Description
This security bulletin contains information about 4 vulnerabilities.
1) Input validation error (CVE-ID: CVE-2023-4512)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in CBOR protocol dissector. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
2) Infinite loop (CVE-ID: CVE-2023-4511)
CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in Bluetooth SDP dissector. A remote attacker can consume all available system resources and cause denial of service conditions.
3) Memory leak (CVE-ID: CVE-2023-4513)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak in Bluetooth SDP dissector. A remote attacker can force the application to leak memory and perform denial of service attack.
4) Input validation error (CVE-ID: CVE-2023-2906)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in CP2179 protocol dissector. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
