Ruby에 포함된 `resolv` gem에서 서비스 거부(DoS) 취약점이 발견되었습니다. | ||
이 취약점은 CVE 번호 [CVE-2025-24294]로 등록되었습니다. | ||
resolv gem을 업그레이드하기를 추천합니다. | ||
|
||
## 세부 내용 | ||
|
||
이 취약점은 DNS 패킷 내에서 압축 해제된 도메인 이름의 길이에 대한 불충분한 검사로 인해 발생합니다. | ||
|
||
공격자는 고도로 압축된 도메인 이름을 포함하는 악의적인 DNS 패킷을 제작할 수 있습니다. | ||
resolv 라이브러리가 이러한 패킷을 파싱할 때, 라이브러리가 압축 해제된 이름의 길이를 제한하지 않기 때문에 이름 압축 해제 과정에서 대량의 CPU 리소스를 소모합니다. | ||
|
||
이러한 리소스 소모로 인해 애플리케이션 스레드가 응답하지 않게 되어 서비스 거부 상태가 발생할 수 있습니다. | ||
|
||
## 해당 버전 | ||
|
||
해당 취약점은 다음 Ruby 시리즈에 포함된 resolv gem에 영향을 미칩니다: | ||
|
||
* Ruby 3.0: `resolv` 0.2.2 이하 | ||
* Ruby 3.1: `resolv` 0.3.0 | ||
* Ruby 3.2: `resolv` 0.6.1 이하 | ||
