CVE-2024-39331
Description
A flaw was found in Emacs. Arbitrary shell commands can be executed without prompting when an Org mode file is opened or when the Org mode is enabled, when Emacs is used as an email client, this issue can be triggered when previewing email attachments.
Statement
To exploit this flaw, an attacker needs to trick a user into opening a crafted Org mode file or previewing a crafted email attachment. For this reason, this flaw has been rated with a Moderate security impact.
Mitigation
Do not open Org mode files or preview email attachments from untrusted sources.
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).

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Files or Directories; Read Application Data
The injected code could access restricted data / files.
Access Control
Technical Impact: Bypass Protection Mechanism
In some cases, injectable code controls authentication; this may lead to a remote vulnerability.
Access Control
Technical Impact: Gain Privileges or Assume Identity
Injected code can access resources that the attacker is directly prevented from accessing.
Integrity,Confidentiality,Availability,Other
Technical Impact: Execute Unauthorized Code or Commands
Code injection attacks can lead to loss of data integrity in nearly all cases as the control-plane data injected is always incidental to data recall or writing. Additionally, code injection can often result in the execution of arbitrary code or at least modify what code can be executed.
Non-Repudiation
Technical Impact: Hide Activities
Often the actions performed by injected control code are unlogged.
