CVE-2026-70457

rsync 3.2.3 before 3.5.0 contains an out-of-bounds write in parse_size_arg() where snprintf()’s return value is used as an index into a .bss-segment array without bounds checking. When truncation occurs, the return value may exceed the array length, causing a write outside the intended bounds and...

CVE-2026-70457 rsync 3.2.3 < 3.5.0 Out-of-Bounds Write via parse_size_arg()

rsync 3.2.3 before 3.5.0 contains an out-of-bounds write in parsesizearg where the return value of snprintf is used directly as an index into a .bss-segment array without bounds checking. When snprintf truncates the formatted size string, the return value equals the number of characters that woul...

CVE-2026-70458 rsync 3.0.0 < 3.5.0 Out-of-Bounds Write via FLAG_HLINKED Handling

rsync 3.0.0 before 3.5.0 contains an out-of-bounds write vulnerability that allows attackers to corrupt memory by triggering HLINKBUMP processing on file entries with the FLAGHLINKED flag set while the hard-link preservation option is inactive. Attackers can exploit the missing FSUM field in the...

CVE-2026-70458 rsync 3.0.0 < 3.5.0 Out-of-Bounds Write via FLAG_HLINKED Handling

rsync 3.0.0 before 3.5.0 contains an out-of-bounds write vulnerability that allows attackers to corrupt memory by triggering HLINKBUMP processing on file entries with the FLAGHLINKED flag set while the hard-link preservation option is inactive. Attackers can exploit the missing FSUM field in the...

CVE-2026-70458

rsync 3.0.0–3.4.x are affected by an out-of-bounds write caused by incorrect HLINK_BUMP handling for file entries with FLAG_HLINKED when hard-link preservation is disabled. The issue stems from a missing F_SUM field in the file_struct layout, allowing memory corruption past the end of the allocat...

CVE-2026-70461

rsync 3.2.5 before 3.5.0 contains a heap out-of-bounds write vulnerability that allows remote unauthenticated attackers to write one attacker-controlled byte past the end of a heap allocation by supplying a crafted files-from entry. Attackers can trigger the vulnerability against a read-only rsyn...

CVE-2026-53794 rsync < 3.5.0 Denial of Service via --max-alloc=0 Logic Error

rsync before 3.5.0 contains a logic error in --max-alloc handling that allows a sender or configuration setting --max-alloc=0 to disable allocation sanity checks entirely rather than enforcing a zero-byte cap. Attackers can exploit this flaw to cause the receiver to attempt unbounded memory...

CVE-2026-53794

The CVE affects rsync prior to 3.5.0. A logic error in --max-alloc handling allows a sender or config setting --max-alloc=0 to bypass allocation sanity checks, causing unbounded memory allocations for file lists/data structures and potential memory exhaustion leading to DoS. Remediation: upgrade ...
