Name of the Vulnerable Software and Affected Versions
rsync versions 3.0.0 through 3.4.x
Description
An out-of-bounds write occurs when triggering HLINK BUMP processing on file entries that have the
FLAG HLINKED flag set while the hard-link preservation option is inactive. This happens because the file struct layout lacks the F SUM field, allowing memory access beyond the allocated structure and resulting in the corruption of adjacent heap or stack data.Recommendations
Update rsync to version 3.5.0 or later.
