Title
Rsync: heap buffer overflow in rsync due to improper checksum length handling
Summary
A heap-based buffer overflow flaw was found in the rsync daemon. This issue is due to improper handling of attacker-controlled checksum lengths (s2length) in the code. When MAX_DIGEST_LEN exceeds the fixed SUM_LENGTH (16 bytes), an attacker can write out of bounds in the sum2 buffer.
Severity ?
9.8 (Critical)
