Description (CNA)
rsync before 3.5.0 contains an out-of-bounds read vulnerability in the sender-side block matching logic that allows a malicious receiver to trigger memory access before the start of an allocated buffer by sending a crafted checksum block with a length of zero. Attackers can send a specially crafted checksum set containing a zero-length block to cause a negative offset calculation during delta computation, resulting in an out-of-bounds read of file data buffer memory on the sender side.
Affected (CNA)
| Vendor / product | Versions |
|---|---|
| RsyncProject / rsync | affected 0 through 3.4.4; unaffected 3.5.0 |
