Description
This security bulletin contains information about 3 vulnerabilities.
1) Input validation error (CVE-ID: CVE-2023-32732)
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. A remote attacker can pass specially crafted input to the application and cause a termination of connection between a HTTP2 proxy and a gRPC server.
2) Input validation error (CVE-ID: CVE-2023-32731)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied input when parsing HTTP2 requests. When gRPC HTTP2 stack raised a header size exceeded error, it skipped parsing the rest of the HPACK frame. This caused any HPACK table mutations to also be skipped, resulting in a desynchronization of HPACK tables between sender and receiver. This could lead to requests from the proxy being interpreted as containing headers from different proxy clients, leading to an information leak that can be used for privilege escalation or data exfiltration.
3) Reachable Assertion (CVE-ID: CVE-2023-1428)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion. A remote attacker can trigger the vulnerability to perform a denial of service (DoS) attack.
