Subject: [PATCH] Fix memory leak in xmlParseBalancedChunkMemoryRecover
|
|
|
|
When doc is NULL, namespace created in xmlTreeEnsureXMLDecl
|
|
is bind to newDoc->oldNs, in this case, set newDoc->oldNs to
|
|
NULL and free newDoc will cause a memory leak.
|
|
|
|
Found with libFuzzer.
|
|
|
|
Closes #82.
