CVE-2024-12084
A heap-based buffer overflow flaw was found in the rsync daemon.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 72.5%, higher than 99% of all known CVEs. Patch or mitigate before the next change window.
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.
