rsync: rsync 2.3.3 < 3.5.0 Path Traversal via --partial-dir/--backup-dir Symlink

A path traversal and symlink vulnerability in rsync allows a malicious sender with write access to write files outside the intended directory. By exploiting symbolic links in conjunction with the --partial-dir or --backup-dir options, an attacker can bypass path restrictions to modify arbitrary...

rsync: rsync: Arbitrary file write via --temp-dir or --link-dest options

A flaw was found in rsync. A remote attacker can exploit this vulnerability by specifying an absolute path using the --temp-dir or --link-dest options. This bypasses the rename-confinement logic, allowing the attacker to write files to arbitrary locations outside the intended destination tree,...

rsync: rsync: Memory corruption via crafted file entries

A flaw was found in rsync. This out-of-bounds write vulnerability allows attackers to corrupt memory by triggering specific processing on specially crafted file entries when hard-link preservation is not active. This can lead to denial of service or other unpredictable system behavior...

rsync: rsync: Heap Out-of-Bounds Write via crafted argument list

A flaw was found in rsync. A remote attacker could exploit an out-of-bounds write vulnerability in the readargs function by sending a specially crafted argument list. This could lead to corruption of adjacent memory, potentially causing a denial of service or, in some cases, arbitrary code...

rsync: rsync: Arbitrary file write via path traversal in --relative mode

A path traversal vulnerability in rsync's --relative mode allows a malicious sender to craft symlink paths, enabling arbitrary file writes outside the destination directory...

rsync: rsync: Denial of Service via handshake stall

A denial of service flaw was found in the rsync daemon. An unauthenticated remote attacker can stall the handshake process by opening multiple concurrent connections and trickling data or stalling prior to module selection. This bypasses standard timeouts and exhausts all available connection...

rsync: rsync: Directory escape via TOCTOU race condition in rrsync

A time-of-check to time-of-use TOCTOU race condition flaw in the rrsync restricted shell wrapper allows authenticated remote attackers to escape directory restrictions. By replacing a validated path component with a symbolic link prior to file transfer execution, an attacker can bypass intended...

rsync: rsync 3.1.0 < 3.5.0 Access Control Bypass via DNS Resolution Failure

A flaw was found in rsync. This vulnerability allows a remote attacker to bypass hostname-based access control rules. By inducing DNS resolution failures, the rsync daemon incorrectly skips deny rules, granting unauthorized access to restricted module file trees...

Astra Linux – Vulnerability in rsync

There is a path traversal vulnerability in rsync. This vulnerability stems from a behavior enabled by the --inc-recursive option, which is a default-enabled option for many client options and can be enabled by the server even if not explicitly enabled by the client. When using the --inc-recursive...

Astra Linux – Vulnerability in rsync

A malicious client acting as the recipient of an rsync file transfer can trigger an out-of-bounds read of a heap-based buffer, through a negative array index. The malicious rsync client requires at least read access to the remote rsync module in order to trigger this issue...

Astra Linux – Vulnerability in rsync

A flaw was discovered in rsync. When the --safe-links option is used, the rsync client fails to properly verify whether a symbolic link destination sent from the server contains another symbolic link within it. This leads to a path traversal vulnerability, which may result in arbitrary file writi...

Important: rsync security, bug fix, and enhancement update

The rsync utility enables the users to copy and synchronize files locally or across a network. Synchronization with rsync is fast because rsync only sends the differences in files over the network instead of sending whole files. The rsync utility is also used as a mirroring tool. Security Fixes:...

CLSA-2026-1788960930 rsync: Fix of 5 CVEs

CVE-2026-70459: guard the parentndx consumer against an empty dirflist so a crafted first incremental file list cannot reach an uninitialised heap slot already blocked in els11 by the CVE-2026-53789 transfer-root rejection; added as defence in depth to match upstream's final state -...

CLSA-2026-1788960665 rsync: Fix of 2 CVEs

CVE-2026-53802: arbitrary file read via symlinked operator-supplied input paths because --filter merge files including per-directory merges and -C .cvsignore, --files-from/--include-from/--exclude-from and the --password-file / daemon secrets file were opened by path, letting a planted symlink...

CLSA-2026-1788956505 rsync: Fix of 3 CVEs

CVE-2026-53784: daemon module-root chdir escape under use chroot = no because changedir reached the module path with a plain chdir, which followed a planted parent-component symlink and served files from outside the module; the module-root chdir now resolves through an ownership-checked ONOFOLLOW...

CLSA-2026-1788953354 rsync: Fix of 6 CVEs

CVE-2026-53784: refuse attacker-planted symlinks when a daemon module resolves its absolute path with "use chroot = no" - CVE-2026-53786: strip the module-dir prefix before checking a client-supplied filter merge file against the module filter list - CVE-2026-53789: keep implied parent...
