CVE-2024-33871
Public on
Last Modified:
Description
A flaw was found in Ghostscript. The "Driver" parameter for the "opvp"/"oprp" device specifies the name of a dynamic library and allows any library to be loaded. This flaw allows a malicious user to send a specially crafted document that, when processed by Ghostscript, could potentially lead to arbitrary code execution with the privileges of the Ghostscript process on the system.
Mitigation
Passing the -dSAFER safety argument on the command line prevents the issue by locking security-related variables after Ghostscript’s initialization. In RHEL 9, -dSAFER is enabled by default, ensuring that insecure commands are rejected in a safer environment. This mitigation is equally effective in RHEL 7 and 8 when -dSAFER is explicitly passed on the command line, addressing the vulnerability that allows insecure commands within PostScript files. Since the OPVP device, cannot be removed, we recommend to use -dSAFER in RHEL 7 and 8 as a practical security measure.

Common Vulnerability Scoring System (CVSS) Score Details
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 Authorities (CNA) source for its products and services (see Red Hat classifications ).
| CVSS v3 Score Breakdown | Red Hat | NVD |
|---|---|---|
| CVSS v3 Base Score | 8.8 | |
| Attack Vector | Network | |
| Attack Complexity | Low | |
| Privileges Required | None | |
| User Interaction | Required | |
| Scope | Unchanged | |
| Confidentiality Impact | High | |
| Integrity Impact | High | |
| Availability Impact | High |

My product is listed as "Under investigation" or "Affected", when will Red Hat release a fix for this vulnerability?
- "Under investigation" doesn't necessarily mean that the product is affected by this vulnerability. It only means that our Analysis Team is still working on determining whether the product is affected and how it is affected.
- "Affected" means that our Analysis Team has determined that this product is affected by this vulnerability and might release a fix to address this in the near future.
What can I do if my product is listed as "Will not fix"?
Available options depend mostly on the Impact of the vulnerability and the current Life Cycle phase of your product. Overall, you have the following options:
- Upgrade to a supported product version that includes a fix for this vulnerability (recommended).
- Apply a mitigation (if one exists).
- Open a This content is not included.support case to request a prioritization of releasing a fix for this vulnerability.
What can I do if my product is listed as "Fix deferred"?
Available options depend mostly on the Impact of the vulnerability and the current Life Cycle phase of your product. Overall, you have the following options:
- Apply a mitigation (if one exists).
- Open a This content is not included.support case to request a prioritization of releasing a fix for this vulnerability.
- Red Hat Engineering focuses on addressing high-priority issues based on their complexity or limited lifecycle support. Therefore, lower-priority issues will not receive immediate fixes.
What is a mitigation?
I have a Red Hat product but it is not in the above list, is it affected?
Why is my security scanner reporting my product as vulnerable to this vulnerability even though my product version is fixed or not affected?
My product is listed as "Out of Support Scope". What does this mean?
