Description
In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Validate buffer length while parsing index
indx_read is called when we have some NTFS directory operations that
need more information from the index buffers. This adds a sanity check
to make sure the returned index buffer length is legit, or we may have
some out-of-bound memory accesses.
