Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

To mitigate CVE-2024-29506, organizations should upgrade Artifex Ghostscript to version 10.03.0 or later once available, as this version addresses the buffer overflow. If you cannot patch yet, implement strict input validation and filtering on PDF files entering the environment, especially from untrusted sources. Employ sandboxing or containerization for Ghostscript processes to limit the impact of potential exploitation. Disable or restrict PDF filter features if not required by the workflow. Monitor logs for crashes or unusual behavior in Ghostscript-related services. Educate users to avoid opening suspicious PDF files and use email gateways or endpoint protection solutions that scan and block malicious documents. For environments where immediate patching is not feasible, consider replacing Ghostscript with alternative PDF processing tools that do not have this vulnerability. Regularly review and update security policies regarding document handling and processing.

Description

Artifex Ghostscript before 10.03.0 has a stack-based buffer overflow in the pdfi_apply_filter() function via a long PDF filter name.

Impact

The primary impact of CVE-2024-29506 is the potential for denial of service through application crashes when processing malicious PDF files containing overly long filter names. In some scenarios, the buffer overflow could be leveraged to execute arbitrary code, though this is not confirmed and would require precise exploitation techniques. Organizations relying on Ghostscript for PDF rendering, printing, or conversion—especially in automated workflows—may face service disruptions or compromise of system integrity. This could affect document management systems, print servers, and software development environments that integrate Ghostscript. The vulnerability does not directly impact confidentiality but could be a foothold for further attacks if exploited for code execution. The lack of authentication requirements and the need only for user interaction increase the risk, especially in environments where untrusted PDFs are handled. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits in the future.

CWE-120Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #11
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
