rsync: rsync: Authorization bypass via `auth users` directive parsing
An authorization bypass flaw was found in the rsync daemon. The auth users directive parser incorrectly handles group names containing spaces due to comma-only tokenization. This flaw causes deny rules to be silently discarded, allowing an authenticated user to bypass restrictions and gain...
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: 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: 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: Unauthorized File Access via Symlink Module Root
A flaw was found in rsync. This path traversal vulnerability allows remote clients to access files outside the intended module root. This occurs when the use chroot option is disabled and the module root path, or a component of it, is a symbolic link. The rsync daemon fails to resolve symlinks...
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: Denial of Service via Zstandard compression thread exhaustion
A denial-of-service flaw in rsync allows remote attackers to exhaust system memory and CPU. By sending requests using the --zt Zstandard compression alias, an attacker can bypass security directives and spawn an excessive number of worker threads...
Important: Red Hat Security Advisory: rsync security, bug fix, and enhancement update
An update for rsync is now available for Red Hat Enterprise Linux 10. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from th...
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: Arbitrary File Read via Symlink Following
A flaw was found in rsync. A local attacker with low privileges can exploit a symlink following vulnerability in the handling of input configuration files, such as those specified by --files-from or --password-file. This allows the attacker to read arbitrary files accessible to the rsync daemon...
rsync: rsync: Information disclosure and denial of service via crafted files-from entry
A flaw was found in rsync. Remote unauthenticated attackers can exploit a heap out-of-bounds write vulnerability by supplying a crafted files-from entry. This entry, containing both an interior and trailing backslash, causes the addimpliedinclude function to under-count the trailing backslash whe...
rsync: rsync: Unauthorized File Access via Symlink Module Root
A flaw was found in rsync. This path traversal vulnerability allows remote clients to access files outside the intended module root. This occurs when the use chroot option is disabled and the module root path, or a component of it, is a symbolic link. The rsync daemon fails to resolve symlinks...
rsync: rsync: Authorization bypass via `auth users` directive parsing
An authorization bypass flaw was found in the rsync daemon. The auth users directive parser incorrectly handles group names containing spaces due to comma-only tokenization. This flaw causes deny rules to be silently discarded, allowing an authenticated user to bypass restrictions and gain...
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: TLS Certificate Validation Bypass allows interception of encrypted sessions
A flaw was found in the rsync-ssl wrapper script's TLS certificate validation. An on-path attacker can present self-signed or invalid certificates to intercept, decrypt, or tamper with encrypted sessions. Because rsync fails to validate the certificate against a trusted CA or verify hostname...
rsync: rsync: Memory corruption via out-of-bounds write in size parsing
An out-of-bounds write vulnerability in rsync's parsesizearg function allows a remote attacker to cause memory corruption. The flaw is triggered when snprintf truncates a formatted size string, resulting in an incorrect memory array index. Exploitation can lead to a denial of service and...
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...
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...
rsync: rsync < 3.5.0 Daemon IP Spoofing via PROXY Protocol Header
A flaw in rsync allows an unauthenticated remote attacker to bypass IP-based access controls by sending a crafted PROXY protocol header with a forged source IP address, granting unauthorized access to restricted resources...
rsync: rsync < 3.5.0 Command Injection via Multiple Code Paths
A command injection vulnerability in rsync allows remote attackers to execute arbitrary commands by supplying shell metacharacters or newlines in unsanitized inputs, such as hostnames or hostspecs. This impacts multiple vectors—including the RSYNCCONNECTPROG variable, daemon hooks, rsync-ssl, and...
