{"schemaVersion":3,"id":"USN-8349-2","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"rsync regression\n\nUSN-8349-1 fixed vulnerabilities in rsync. The update introduced multiple\nregressions in rsync functionality. This update fixes the problem.\n\nOriginal advisory details:\n\n Calum Hutton discovered that rsync contained a heap-based out-of-bounds\n read when handling file transfers. A remote attacker with read access\n to an rsync server could possibly use this issue to cause a denial of\n service. (CVE-2025-10158)\n\n Batuhan Sancak, Damien Neil, and Michael Stapelberg discovered that\n rsync daemons configured without chroot protection were exposed to a\n race condition on parent path components. A local attacker with write\n access to a module could possibly use this issue to overwrite files,\n obtain sensitive information, or escalate privileges.\n (CVE-2026-29518)\n\n It was discovered that rsync did not properly validate a length value\n while sorting extended attributes. An attacker could possibly use this\n issue to cause a denial of service. (CVE-2026-41035)\n\n It was discovered that rsync performed reverse-DNS lookups after\n chrooting in some daemon configurations. A remote attacker could\n possibly use this issue to bypass hostname-based access controls and\n access network services. (CVE-2026-43617)\n\n Omar Elsayed discovered that rsync did not properly check for integer\n overflows while decoding compressed tokens. A remote attacker could\n possibly use this issue to obtain sensitive information.\n (CVE-2026-43618)\n\n Andrew Tridgell discovered that rsync did not fully fix a symlink race\n condition in path-based system calls for daemons configured without\n chroot protection. A local attacker could possibly use this issue to\n overwrite files, obtain sensitive information, or escalate privileges.\n (CVE-2026-43619)\n\n Pratham Gupta discovered that rsync did not properly validate an index\n while processing file lists. A remote attacker could possibly use this\n issue to cause rsync to crash, resulting in a denial of service.\n (CVE-2026-43620)\n\n Michal Ruprich discovered that rsync contained an off-by-one error\n while handling HTTP proxy responses. An attacker able to intercept network\n communications or a malicious proxy server could possibly use this issue to\n cause a denial of service.
