rsync: rsync: Denial of Service via Algorithmic Complexity

A flaw was found in rsync. A remote attacker can exploit an algorithmic complexity vulnerability within the hashsearch function by sending a specially crafted file list. This can lead to the exhaustion of the receiver's CPU resources, causing a sustained denial of service DoS...

CVE-2026-70459

A flaw was found in rsync. A remote attacker could send a specially crafted file list to the rsync daemon. This could lead to a null pointer dereference, causing the daemon to crash and resulting in a Denial of Service DoS. Mitigation To mitigate this issue, restrict network access to the rsync...

SUSE CVE-2026-53789

JLSEC-2026-631 Rsync version 3.4.2 and prior contain a receiver-side out-of-bounds array read vulnerability in...

Rsync version 3.4.2 and prior contain a receiver-side out-of-bounds array read vulnerability in recvfiles in receiver.c that allows a malicious rsync server to crash the rsync client process. Attackers can exploit the vulnerability by setting CFINCRECURSE in compatibility flags and sending a...

OESA-2026-2552 rsync security update

Rsync is an open source utility that provides fast incremental file transfer. It uses the "rsync algorithm" which provides a very fast method for bringing remote files into sync. It does this by sending just the differences in the files across the link, without requiring that both sets of files a...
