Summary
rsync 3.2.5 < 3.5.0 Heap Out-of-Bounds Write via files-from Entry
Details

rsync 3.2.5 before 3.5.0 contains a heap out-of-bounds write vulnerability that allows remote unauthenticated attackers to write one attacker-controlled byte past the end of a heap allocation by supplying a crafted files-from entry. Attackers can trigger the vulnerability against a read-only rsync daemon module by providing a files-from entry containing both an interior and trailing backslash, causing the addimpliedinclude() function to under-count the trailing backslash when sizing the destination buffer.
