Astra Linux – Vulnerability in rsync

A flaw was discovered in rsync that can be triggered when rsync compares file checksums. This flaw allows an attacker to manipulate the checksum length s2length, causing a comparison between a checksum and uninitialized memory, and resulting in the leakage of one byte of uninitialized stack data ...

Astra Linux – Vulnerability in rsync

A flaw was discovered in rsync. This vulnerability stems from a race condition that occurs during rsync’s handling of symbolic links. The default behavior of rsync when encountering symbolic links is to skip them. If an attacker replaces a regular file with a symbolic link at the appropriate time...

CVE-2026-70460

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...

CVE-2026-70454

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...

CVE-2026-70463

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...

CVE-2026-70458

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. Mitigation...

CVE-2026-70464

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...

CVE-2026-53784

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...

Fedora 44 : rsync (2026-bfae8723e2)

The remote Fedora 44 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-bfae8723e2 advisory. New version 3.5.0. Includes fixes for following CVEs: CVE-2026-53783, CVE-2026-53784, CVE-2026-53785, CVE-2026-53786, CVE-2026-53788, CVE-2026-53789...

CVE-2026-53793

A flaw was found in rsync. This vulnerability allows remote clients to bypass path confinement, a security measure designed to restrict file access. By crafting specific paths that include a '/./' boundary marker within a chroot environment, an attacker can gain unauthorized read or write access ...

CVE-2026-70462

A flaw was found in rsync. A remote attacker can exploit a signed integer overflow vulnerability in the I/O timeout implementation by sending specially crafted messages. These messages can disable connection timeouts, causing idle or stalled connections to persist indefinitely. This leads to...

CVE-2026-53795

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,...

CVE-2026-53794

A flaw was found in rsync. A logic error in the --max-alloc handling allows a remote attacker to disable memory allocation sanity checks by setting --max-alloc=0. This can lead to the receiver attempting unbounded memory allocations, potentially exhausting available memory and causing a denial of...

CVE-2026-70452

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. Mitigation To mitigate this issue...

CVE-2026-53790

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...

CVE-2026-53791

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. Mitigation Restrict rsync daemon TCP/873 to the trusted proxy only CME-202...
