Thus it is is possible for a user with reduced privileges to install a malicious libcrypto library into a path to which they have write access, invoke the container-executor command, and have their modified library executed as root.\nIf the YARN cluster is accepting work from remote (authenticated) users, and these users\u0027 submitted job are executed in the physical host, rather than a container, then the CVE permits remote users to gain root privileges.\n\nThe fix for the vulnerability is to revert the change, which is done in  YARN-11441 https://issues.apache.org/jira/browse/YARN-11441 , \"Revert YARN-10495\". This patch is in hadoop-3.3.5.\n\nTo determine whether a version of container-executor is vulnerable, use the readelf command. If the RUNPATH or RPATH value contains the relative path \"./lib/native/\" then it  is at risk\n\n$ readelf -d container-executor|grep \u0027RUNPATH\\|RPATH\u0027 \n0x000000000000001d (RUNPATH)  \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 Library runpath: [$ORIGIN/:../lib/native/]\n\nIf it does not, then it is safe:\n\n$ readelf -d container-executor|grep \u0027RUNPATH\\|RPATH\u0027 \n0x000000000000001d (RUNPATH)  \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 Library runpath: [$ORIGIN/]\n\nFor an at-risk version of container-executor to enable privilege escalation, the owner must be root and the suid bit must be set\n\n$ ls -laF /opt/hadoop/bin/container-executor\n---Sr-s---. 1 root hadoop 802968 May 9 20:21 /opt/hadoop/bin/container-executor\n\nA safe installation lacks the suid bit; ideally is also not owned by root.\n\n$ ls -laF /opt/hadoop/bin/container-executor\n-rwxr-xr-x. 1 yarn hadoop 802968 May 9 20:21 /opt/hadoop/bin/container-executor\n\nThis configuration does not support Yarn Secure Containers, but all other hadoop services, including YARN job execution outside secure containers continue to work.\n\n"
