A remote attacker with read access\nto an rsync server could possibly use this issue to cause a denial of\nservice. This issue only affected Ubuntu 22.04 LTS, Ubuntu 24.04 LTS,\nand Ubuntu 25.10. (CVE-2025-10158)\n\nBatuhan Sancak, Damien Neil, and Michael Stapelberg discovered that\nrsync daemons configured without chroot protection were exposed to a\nrace condition on parent path components. A local attacker with write\naccess to a module could possibly use this issue to overwrite files,\nobtain sensitive information, or escalate privileges.\n(CVE-2026-29518)\n\nIt was discovered that rsync did not properly validate a length value\nwhile sorting extended attributes. An attacker could possibly use this\nissue to cause a denial of service. (CVE-2026-41035)\n\nIt was discovered that rsync performed reverse-DNS lookups after\nchrooting in some daemon configurations. A remote attacker could\npossibly use this issue to bypass hostname-based access controls and\naccess network services. (CVE-2026-43617)\n\nOmar Elsayed discovered that rsync did not properly check for integer\noverflows while decoding compressed tokens. A remote attacker could\npossibly use this issue to obtain sensitive information.\n(CVE-2026-43618)\n\nAndrew Tridgell discovered that rsync did not fully fix a symlink race\ncondition in path-based system calls for daemons configured without\nchroot protection. A local attacker could possibly use this issue to\noverwrite files, obtain sensitive information, or escalate privileges.\n(CVE-2026-43619)\n\nPratham Gupta discovered that rsync did not properly validate an index\nwhile processing file lists. A remote attacker could possibly use this\nissue to cause rsync to crash, resulting in a denial of service.\n(CVE-2026-43620)\n\nMichal Ruprich discovered that rsync contained an off-by-one error\nwhile handling HTTP proxy responses. An attacker able to intercept network\ncommunications or a malicious proxy server could possibly use this issue to\ncause a denial of service.
