Change subject: IMPALA-5088: Fix heap buffer overflow ...................................................................... IMPALA-5088: Fix heap buffer overflow In a recent patch, we introduced a change where we are incorrectly copying a buffer. We are reading past the end of a buffer during the copy. Even though we would never read the data that was copied from past the end of the buffer, this could cause a crash if the allocation is sitting on the edge of an unmapped area of memory. This also caused the ASAN build to fail. The issue is fixed by never accessing memory that is past the end of the buffer Change-Id: Ia68d69b35d53934e6f1aae2e1696503d17660ca2 --- M be/src/exprs/aggregate-functions-ir.cc 1 file changed, 7 insertions(+), 4 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/41/6441/1 -- To view, visit http://gerrit.cloudera.org:8080/6441 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: newchange Gerrit-Change-Id: Ia68d69b35d53934e6f1aae2e1696503d17660ca2 Gerrit-PatchSet: 1 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Taras Bobrovytsky <[email protected]>
