Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2021-22207)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the MS-WSP dissector in Wireshark. A remote attacker can send specially crafted packets over the network or convince the victim to read a malformed packet trace file and consume excessive CPU resources, causing denial of service condition.
2) Infinite loop (CVE-ID: CVE-2021-22222)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the DVB-S2-BB dissector. A remote attacker can consume all available system resources and cause denial of service conditions.
3) Input validation error (CVE-ID: CVE-2021-22235)
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 within the DNP dissector. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
4) Input validation error (CVE-ID: CVE-2021-39920)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation in the IPPUSB dissector. A remote attacker can send specially crafted packets through the application and perform a denial of service (DoS) attack.
5) Input validation error (CVE-ID: CVE-2021-39921)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation in the Modbus dissector. A remote attacker can send specially crafted packets through the application and perform a denial of service (DoS) attack.
6) Input validation error (CVE-ID: CVE-2021-39922)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation in the C12.22 dissector. A remote attacker can send specially crafted packets through the application and perform a denial of service (DoS) attack.
7) Infinite loop (CVE-ID: CVE-2021-39923)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in the PNRP dissector. A remote attacker can send specially crafted packets through the application, consume all available system resources and perform a denial of service (DoS) attack.8) Infinite loop (CVE-ID: CVE-2021-39924)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in the Bluetooth DHT dissector. A remote attacker can send specially crafted packets through the application, consume all available system resources and perform a denial of service (DoS) attack.
9) Input validation error (CVE-ID: CVE-2021-39925)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation in the Bluetooth SDP dissector. A remote attacker can send specially crafted packets through the application and perform a denial of service (DoS) attack.
10) Input validation error (CVE-ID: CVE-2021-39926)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation in the Bluetooth HCI_ISO dissector. A remote attacker can send specially crafted packets through the application and perform a denial of service (DoS) attack.
11) Input validation error (CVE-ID: CVE-2021-39928)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation in the IEEE 802.11 dissector. A remote attacker can send specially crafted packets through the application and perform a denial of service (DoS) attack.
12) Input validation error (CVE-ID: CVE-2021-39929)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation in the Bluetooth DHT dissector. A remote attacker can send specially crafted packets through the application and perform a denial of service (DoS) attack.
