[ALSA-2026:74095] Important: rsync security, bug fix, and enhancement update
Type:
security
Severity:
important
Release date:
2026-10-01
Description:
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: 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: 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: 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): * Fix latest CVEs in rsync in AlmaLinux8 (JIRA:AlmaLinux-256903) * rsync-3.1.3-27.el8_10 regression: rsync daemon rejects legitimate cross-device symlinks with EXDEV when use chroot = no (JIRA:AlmaLinux-239553) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
