Summary
rsync 3.0.0 < 3.5.0 Out-of-Bounds Write via FLAG_HLINKED Handling
Details

rsync 3.0.0 before 3.5.0 contains an out-of-bounds write vulnerability that allows attackers to corrupt memory by triggering HLINKBUMP processing on file entries with the FLAGHLINKED flag set while the hard-link preservation option is inactive. Attackers can exploit the missing FSUM field in the filestruct layout to access memory past the end of the allocated structure, corrupting adjacent heap or stack data.
