Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Stack-based buffer overflow

EUVDB-ID: #VU102518

Risk: Medium

CVSSv4.0: 6.6 [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]

CVE-ID: CVE-2024-55605

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error in multiple transforms. A remote attacker can send very large packets to the application, trigger a stack-based buffer overflow and perform a denial of service (DoS) attack.

Below is the list of affected transforms:

  • to_lowercase
  • to_uppercase
  • strip_whitespace
  • compress_whitespace
  • dotprefix
  • header_lowercase
  • strip_pseudo_headers
  • url_decode
  • xor

2) Buffer overflow

EUVDB-ID: #VU102517

Risk: Low

CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2024-55626

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

4) Asymmetric Resource Consumption (Amplification)

EUVDB-ID: #VU102515

Risk: Medium

CVSSv4.0: 6.6 [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]

CVE-ID: CVE-2024-55628

CWE-ID: CWE-405 - Asymmetric Resource Consumption (Amplification)

Exploit availability: No

Description

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

The vulnerability exists due to incorrect handling of DNS resource name compression. A remote attacker can send small DNS messages containing very large hostnames and force the software to render very large DNS log records, leading to denial of service conditions.

Mitigation

Install updates from vendor's website.

5) Input validation error

EUVDB-ID: #VU102514

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2024-55629

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The vulnerability exists due to incorrect handling of TCP streams with TCP urgent data (out of band data), which can lead to Suricata analyzing data differently than the applications at the TCP endpoints. A remote attacker can bypass generic detection when using TCP urgent support.

Mitigation

Install updates from vendor's website.
