https://bugzilla.suse.com/show_bug.cgi?id=1237636 Bug ID: 1237636 Summary: VUL-0: CVE-2025-27144: traefik: github.com/go-jose/go-jose/v4: Go JOSE's Parsing Vulnerable to Denial of Service Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.5 Hardware: Other URL: https://smash.suse.de/issue/441954/ OS: Other Status: NEW Whiteboard: CVSSv3.1:SUSE:CVE-2025-27144:7.5:(AV:N/AC:L/PR:N/UI:N/ S:U/C:N/I:N/A:H) Severity: Major Priority: P5 - None Component: Security Assignee: alexandre.vicenzi@suse.com Reporter: emanuele.cappello@suse.com QA Contact: security-team@suse.de Blocks: 1237608 Target Milestone: --- Found By: --- Blocker: --- Go JOSE provides an implementation of the Javascript Object Signing and Encryption set of standards in Go, including support for JSON Web Encryption (JWE), JSON Web Signature (JWS), and JSON Web Token (JWT) standards. In versions on the 4.x branch prior to version 4.0.5, when parsing compact JWS or JWE input, Go JOSE could use excessive memory. The code used strings.Split(token, ".") to split JWT tokens, which is vulnerable to excessive memory consumption when processing maliciously crafted tokens with a large number of `.` characters. An attacker could exploit this by sending numerous malformed tokens, leading to memory exhaustion and a Denial of Service. Version 4.0.5 fixes this issue. As a workaround, applications could pre-validate that payloads passed to Go JOSE do not contain an excessive number of `.` characters.
