CVE-2024-12084

Severity CVSS v4.0:
Pending analysis
Type:
CWE-122 Heap-based Buffer Overflow
Publication date:
15/01/2025

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.
