Vulnerability Title
Kraken Agents Peer-to-Peer Download Cache Poisoning via Digest Verification Bypass
Vulnerability Description
Kraken agents fail to verify peer-to-peer downloaded blobs against their requested SHA-256 digest before committing to the content-addressable cache, relying only on CRC32 checksums for piece validation. Attackers on the agent-to-agent path or malicious peers can supply substituted content with forged CRC32 corrections that passes per-piece checks, poisoning the cache with attacker-chosen container image layers or manifests that are re-seeded and executed by other hosts.

Uber Open Source Kraken 加密问题漏洞
Vulnerability Description
Uber Open Source Kraken是Uber Open Source组织开源的一个基于点对点协议的容器镜像分发工具。 Uber Open Source Kraken 0.1.27及之前版本存在加密问题漏洞,该漏洞源于未能验证对等下载的blob与请求的SHA-256摘要,仅依赖CRC32校验和进行分片验证,可能导致攻击者通过代理间路径或恶意对等节点提供替换内容,利用伪造的CRC32校验和通过检查,污染缓存,导致其他主机重新播种并执行攻击者选择的容器镜像层或清单。
