IMPALA-12661: Fix ASAN heap-use-after-free in IcebergMetadataScanNode The ASAN builds detected that the IcebergMetadataScanNode uses heap allocated memory after it has been freed. In CreateFieldAccessors() method, during tree traversal, the current_type variable is reassigned to its children which is part of of the object. However, by the end of the assignment the rhs object will be destroyed. To fix this issue, the variable was replaced with a pointer. Testing: - Ran tests on ASAN build Change-Id: I6df9c9cb6914a0c6c93b61aa0dd02acfdba68851 --- M be/src/exec/iceberg-metadata/iceberg-metadata-scan-node.cc 1 file changed, 4 insertions(+), 4 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/29/20829/1 -- To view, visit http://gerrit.cloudera.org:8080/20829 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: I6df9c9cb6914a0c6c93b61aa0dd02acfdba68851 Gerrit-Change-Number: 20829 Gerrit-PatchSet: 1 Gerrit-Owner: Tamas Mate <tma...@apache.org>
