Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2022-36764)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the Tcg2MeasurePeImage() function. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Buffer overflow (CVE-ID: CVE-2023-45230)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary within a long server ID option in DHCPv6 client. A remote attacker on the local network can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Infinite loop (CVE-ID: CVE-2023-45232)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when parsing unknown options in the Destination Options header of IPv6. A remote attacker can consume all available system resources and cause denial of service conditions.
4) Infinite loop (CVE-ID: CVE-2023-45233)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when parsing a PadN option in the Destination Options header of IPv6. A remote attacker can consume all available system resources and cause denial of service conditions.
5) Buffer overflow (CVE-ID: CVE-2023-45235)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when handling Server ID option from a DHCPv6 proxy Advertise message. A remote attacker on the local network can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
