2) Buffer overflow (CVE-ID: CVE-2024-34364)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the mirror response. A remote user can trigger memory corruption and cause a denial of service condition on the target system.

3) Use of Weak Credentials (CVE-ID: CVE-2024-23326)

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to the Envoy incorrectly accepts HTTP 200 response for entering upgrade mode. A remote attacker can gain access to sensitive information on the system.

4) Use-after-free (CVE-ID: CVE-2024-34362)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error in EnvoyQuicServerStream. A remote attacker can cause a denial of service condition on the target system.

5) Uncaught Exception (CVE-ID: CVE-2024-34363)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to uncaught exception in the nlohmann JSON library. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

6) Use-after-free (CVE-ID: CVE-2024-32974)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error in EnvoyQuicServerStream::OnInitialHeadersComplete() function. A remote attacker can cause a denial of service condition on the target system.

7) Integer underflow (CVE-ID: CVE-2024-32975)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to integer underflow in QuicheDataReader::PeekVarInt62Length() function. A remote attacker can send a specially crafted request to the affected application, trigger integer underflow and cause a denial of service condition on the target system.
