CVE-2025-68972
Description
A flaw was found in GnuPG. An adversary can exploit this vulnerability by crafting a signed message that includes a form feed character (\f) at the end of a plaintext line. This allows the adversary to append additional, unsigned text to the message while the signature verification still reports success. This issue leads to an integrity bypass, potentially enabling the spoofing of signed communications.
Statement
This vulnerability is rated Moderate for Red Hat products as it affects GnuPG, allowing an attacker to append unsigned text to a signed message while signature verification still reports success. This integrity bypass could lead to spoofing of signed communications, impacting the authenticity of signed data in Red Hat Enterprise Linux environments.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
