Last modified
CVE-2024-12084 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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. EPSS estimates a 72.06% chance of exploitation in the next 30 days.
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.
