漏洞详情
来源:https://acce报2ss.redhat.com/errata/RHSA-2021:1005
1.CVE-2021-3121 CVSS评分:8.6 严重程度:中
在1.3.2之前的github.c10om/gogo/protobuf中发现了一个漏洞,该漏洞允许在解组某些protobuf对象时进行越界访问。此缺陷使远程攻击者可以发送原始的probubuf消息,从而导致拒绝40服务。此漏洞带来的最大威胁是可用性。
2.CVE-2021-20206 CVSS评分:7.2 严重程度:中
在containernetworking / cni中发现了对路径名缺陷的不6:当限制。在网络配置的“类型”字段中指定要加载的插件时,可以使用特殊元素(例如“ ../”分隔符)来引用系统上其他位置的二进制文件。这个缺陷使攻击者可以执行除cni插件/类型以外的红帽其他现有二进制文件,例如“ reboot”。此漏洞带来的最大威胁是机密性,完整性和系统可用性。
