Amazon Linux 2023: CVE-2025-65637: Important priority package update for amazon-ecr-credential-helper (Multiple Advisories)

A denial-of-service vulnerability exists in github.com/sirupsen/logrus when using Entry.Writer() to log a single-line payload larger than 64KB without newline characters. Due to limitations in the internal bufio.Scanner, the read fails with "token too long" and the writer pipe is closed, leaving Writer() unusable and causing application unavailability (DoS). This affects versions < 1.8.3, 1.9.0, and 1.9.2. The issue is fixed in 1.8.3, 1.9.1, and 1.9.3+, where the input is chunked and the writer continues to function even if an error is logged.
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.
