Summary
Important: rsync security, bug fix, and enhancement update
Details

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 Fix(es):

  • rsync: rsync 2.3.3 < 3.5.0 Path Traversal via --partial-dir/--backup-dir Symlink (CVE-2026-70460)
  • rsync: rsync: TLS Certificate Validation Bypass allows interception of encrypted sessions (CVE-2026-70454)
  • rsync: rsync: Arbitrary file deletion via malicious file list (CVE-2026-53789)
  • rsync: rsync < 3.5.0 Command Injection via Multiple Code Paths (CVE-2026-53790)
  • rsync: rsync: Memory corruption via crafted file entries (CVE-2026-70458)
  • rsync: rsync: Denial of Service via handshake stall (CVE-2026-70464)
  • rsync: rsync: Local Privilege Escalation via Symlink Following (CVE-2026-53803)
  • rsync: rsync: Unauthorized File Access via Symlink Module Root (CVE-2026-53784)
  • rsync: rsync: Authorization bypass via auth users directive parsing (CVE-2026-70463)
  • rsync: rsync 3.1.0 < 3.5.0 Access Control Bypass via DNS Resolution Failure (CVE-2026-70452)
  • rsync: rsync < 3.5.0 Daemon IP Spoofing via PROXY Protocol Header (CVE-2026-53791)
  • rsync: rsync: Arbitrary file write via --temp-dir or --link-dest options (CVE-2026-53795)
  • rsync: rsync: Heap Out-of-Bounds Write via crafted argument list (CVE-2026-70456)
  • rsync: rsync < 3.5.0 Path Confinement Bypass via /./ Boundary Marker in Chroot Mode (CVE-2026-53793)
  • rsync: rsync: Denial of Service via Algorithmic Complexity (CVE-2026-70453)
  • rsync: rsync: Denial of Service via Zstandard compression thread exhaustion (CVE-2026-70455)
  • rsync: rsync: Memory corruption via out-of-bounds write in size parsing (CVE-2026-70457)
  • rsync: rsync: Information disclosure and denial of service via crafted files-from entry (CVE-2026-70461)
  • rsync: rsync: Arbitrary File Read via Symlink Following (CVE-2026-53802)
  • rsync: rsync: Arbitrary file write via path traversal in --relative mode (CVE-2026-53785)
  • rsync: rsync: Directory escape via TOCTOU race condition in rrsync (CVE-2026-53783)

Bug Fix(es) and Enhancement(s):

  • Rebase rsync to version 3.5.0 in AlmaLinux10 (JIRA:AlmaLinux-246094)

Taxonomy of the tags.




Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Sightings

Author Source Type Date Other

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

    Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
