Title
Rsync: Out of bounds array access via negative index
Summary
A malicious client acting as the receiver of an rsync file transfer can trigger an out of bounds read of a heap based buffer, via a negative array index. The malicious rsync client requires at least read access to the remote rsync module in order to trigger the issue.
Severity ?
