CVE-2026-70456

rsync 3.0.1 before 3.5.0 is affected by an out-of-bounds write in read_args(), enabling a remote attacker to corrupt adjacent heap memory by sending a crafted argument list. When argv allocation is exactly full, the trailing NULL terminator is written one slot past the allocation, causing heap co...

CVE-2026-70456

rsync 3.0.1 before 3.5.0 contains an out-of-bounds write vulnerability in the readargs function that allows a malicious sender to corrupt adjacent heap memory by sending a crafted argument list. When the argument count causes the argv allocation to be exactly full, the trailing NULL terminator is...

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-2026-70457

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-2026-70458

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-2026-70458 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...
