Multiple race conditions in HtmlCleaner before 2.6, as used in Open-Xchange AppSuite 7.2.2 before rev13 and other products, allow remote authenticated users to read the private e-mail of other persons in opportunistic circumstances by leveraging lack of thread safety and performing a rapid series of (1) mail-sending or (2) draft-saving operations.
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
