Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.

Red HatModerate

The assigned Moderate severity reflects that while the vulnerability can be exploited remotely, it requires an attacker to have some level of privilege on the system. The impact is primarily on the integrity of email messages, without affecting confidentiality or availability. This aligns with Red Hat's definition of…

Workaround published by Red Hat

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.
