Summary
rsync vulnerabilities
Details

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. (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)
