- Summary
- rsync: Fix of 7 CVEs
- Details
-
- CVE-2026-53783: rrsync restricted-directory escape through a symlinked or raced path component, --copy-unsafe-links, -D or a symlinked log file; partial, the dir-merge rule escape needs --confine-root (3.5.0)
- CVE-2026-53790: the daemon's pre-xfer/post-xfer exec hooks and RSYNC_CONNECT_PROG expanded %RSYNC_*%/%H into a shell command without escaping them
- CVE-2026-70453: unbounded hash_search() chain walk let a crafted run of equal weak checksums pin the sender at 100% CPU; the per-offset walk is now bounded
- CVE-2026-70456: heap out-of-bounds write in read_args() when the peer's argument count lands exactly on the argv allocation; room for the trailing NULL is reserved
- CVE-2026-70458: out-of-bounds write from a file entry marked FLAG_HLINKED accepted while hard-link preservation was inactive; the flag is now gated and excludes dirs
- CVE-2026-70462: a peer-supplied MSG_IO_TIMEOUT could disable or overflow the client's own I/O timeout; non-positive values are ignored and the value is capped
- CVE-2026-70464: the pre-transfer daemon handshake ran with no I/O timeout, so an unauthenticated peer could hold every max-connections slot indefinitely
- safe_arg() left an uninitialized heap byte in remote-shell filename args
