Descriptions
Redis is an open source, in-memory database that persists on disk. In versions starting from 7.0.0 to before 8.0.2, a stack-based buffer overflow exists in redis-check-aof due to the use of memcpy with strlen(filepath) when copying a user-supplied file path into a fixed-size stack buffer. This allows an attacker to overflow the stack and potentially achieve code execution. This issue has been patched in version 8.0.2.
A flaw was found in Redis. Using memcpy with the strlen filepath when copying a user-supplied file path into a fixed-size stack buffer in redis-check-aof results in a stack-based buffer overflow. This flaw allows a local attacker to trigger the overflow by providing a specially crafted file path, allowing potential code execution. The primary consequence is a possible denial of service.
An update for valkey is now available for Red Hat Enterprise Linux 10. Issues addressed include buffer overflow, denial of service, and out of bounds write vulnerabilities.
