In rsync 3.0.1 through 3.4.1, receive_xattr relies on an untrusted length value during a qsort call, leading to a receiver use-after-free. The victim must run rsync with -X (aka --xattrs). On Linux, many (but not all) common configurations are vulnerable. Non-Linux platforms are more widely vulnerable.

    Calum Hutton discovered that rsync contained a heap-based out-of-bounds read when handling file transfers.
    A remote attacker with read access to an rsync server could possibly use this issue to cause a denial of     service. This issue only affected Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 25.10. (CVE-2025-10158)

    Batuhan Sancak, Damien Neil, and Michael Stapelberg discovered that rsync daemons configured without     chroot protection were exposed to a race condition on parent path components. A local attacker with write     access to a module could possibly use this issue to overwrite files, obtain sensitive information, or     escalate privileges. (CVE-2026-29518)

    It was discovered that rsync did not properly validate a length value while sorting extended attributes.
    An attacker could possibly use this issue to cause a denial of service. (CVE-2026-41035)

    It was discovered that rsync performed reverse-DNS lookups after chrooting in some daemon configurations.
    A remote attacker could possibly use this issue to bypass hostname-based access controls and access     network services. (CVE-2026-43617)

    Omar Elsayed discovered that rsync did not properly check for integer overflows while decoding compressed     tokens. A remote attacker could possibly use this issue to obtain sensitive information. (CVE-2026-43618)

    Andrew Tridgell discovered that rsync did not fully fix a symlink race condition in path-based system     calls for daemons configured without chroot protection. A local attacker could possibly use this issue to     overwrite files, obtain sensitive information, or escalate privileges. (CVE-2026-43619)

    Pratham Gupta discovered that rsync did not properly validate an index while processing file lists. A     remote attacker could possibly use this issue to cause rsync to crash, resulting in a denial of service.
    (CVE-2026-43620)

    Michal Ruprich discovered that rsync contained an off-by-one error while handling HTTP proxy responses. An     attacker able to intercept network communications or a malicious proxy server could possibly use this     issue to cause a denial of service. (CVE-2026-45232)

The remote Fedora 43 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-d4d8ae2bdc advisory.

    Fixing various bugs from Upstream.

    I did not do a rebase since the Upstream stopped supporting the rsync-patches repo. I accepted this change     in Rawhide but it changes the usage of one option that is no longer available in rsync. This is why I     avoided the rebase in older stable branches.
