Red Hat: CVE-2025-65637: github.com/sirupsen/logrus: github.com/sirupsen/logrus: Denial-of-Service due to large single-line payload (Multiple Advisories)

A denial-of-service vulnerability in github.com/sirupsen/logrus occurs when Entry.Writer() processes a single-line payload larger than 64KB with no newline characters. Due to a limitation in Go’s internal bufio.Scanner, the read operation fails with a “token too long” error, causing the underlying writer pipe to close. In affected versions, this leaves the Writer interface unusable and can disrupt logging functionality, potentially degrading application availability.
