Description

This security bulletin contains information about 7 vulnerabilities.


1) Infinite loop (CVE-ID: CVE-2024-32976)

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. A remote attacker can consume all available system resources and cause denial of service conditions.


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

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/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 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)

CWE-ID: CWE-1391 - Use of Weak Credentials

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green


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)

CWE-ID: CWE-248 - Uncaught Exception

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:P/U:Green


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)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green


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)

CWE-ID: CWE-191 - Integer underflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green


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.
