> Possibility of overflow in file length calculation

> Key: OAK-2388
> URL: https://issues.apache.org/jira/browse/OAK-2388
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: oak-lucene
> Reporter: Chetan Mehrotra
> Assignee: Chetan Mehrotra
> Fix For: 1.0.10, 1.1.5
>
>
> In OakDirectory the length of a file is calculated in following way
> {code:title=OakDirectory|linenumbers=true}
> public OakIndexFile(String name, NodeBuilder file) {
> ...
> this.blobSize = determineBlobSize(file);
> this.blob = new byte[blobSize];
> PropertyState property = file.getProperty(JCR_DATA);
> if (property != null && property.getType() == BINARIES) {
> this.data = newArrayList(property.getValue(BINARIES));
> } else {
> this.data = newArrayList();
> }
> this.length = data.size() * blobSize;
> if (!data.isEmpty()) {
> Blob last = data.get(data.size() - 1);
> this.length -= blobSize - last.length();
> }
> {code}
> In above calculation its possible to have an overflow in
> bq. this.length = data.size() * blobSize;
> As multiplication of two integers result in an integer [1]
> [1]
