Vulnerability Details
The vulnerability identified as CVE-2024-29510 allows for memory corruption and SAFER sandbox bypass via format string injection with a uniprint device. This vulnerability is officially classified as medium severity with a CVSS score of 6.3. The affected product is Artifex Ghostscript, specifically versions prior to 10.03.1. The vulnerability was published on July 3, 2024, and is classified under CWE-693.
Technical Analysis
The root cause of this vulnerability is a failure to properly handle format strings within the uniprint device of Ghostscript. This oversight can lead to memory corruption when an attacker crafts an input that exploits this weakness. The attack vector for this vulnerability is local, requiring the attacker to have some level of access to the system.
The attack complexity is assessed as low, indicating that an attacker with minimal skills could exploit this vulnerability. No privileges are required to exploit this vulnerability, but user interaction is necessary since the attack involves the input from a user. The confidentiality impact is high, allowing unauthorized access to sensitive information, while the integrity and availability impacts are none.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive data or system resources. The blast radius for this vulnerability can be significant, especially in environments where Ghostscript is widely deployed. Organizations should assess their exposure and implement remediation measures as soon as possible.
Given the CVSS score of 6.3, the urgency for remediation is medium. Organizations should schedule remediation as part of their priority patch cycle to ensure that they are protected against possible exploitation.
