CVE-2024-12084
9.8
CRITICAL · CVSS 3.1 · EPSS 72.1% (pctl 99)
Patch early
EPSS 72.1% — above the 10% action threshold.
Description
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.
