This vulnerability allows a heap-based buffer overflow in GNOME GdkPixbuf before version 2.42.8 when compositing or clearing frames in GIF files. This overflow is controllable and could be abused for code execution, especially on 32-bit systems. With a CVSS score of 7.8, categorized as high severity, this vulnerability presents a notable risk to organizations using affected versions.
Risk to organizations includes potential unauthorized code execution, which can lead to further system compromise or data loss. Given the ease of exploitation, organizations should prioritize patching immediately.
As of now, there are no known public exploits associated with this vulnerability, but the nature of heap-based buffer overflows makes it critical for defenders to remain vigilant.
Organizations should address this vulnerability in their priority patch cycle to mitigate risks effectively.
Vulnerability Details
The official CVE description states that GNOME GdkPixbuf before 2.42.8 allows a heap-based buffer overflow. This vulnerability is categorized under CWE-190, indicating an integer overflow. The publication date of the vulnerability is July 24, 2022.
The CVSS version is 3.1, with a vector string of CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating a local attack vector requiring user interaction. The confidentiality, integrity, and availability impacts are all rated high.
Technical Analysis
The root cause of this vulnerability lies in the mishandling of buffer sizes during the processing of GIF files. The attack vector is local, requiring the attacker to have access to the system to exploit this vulnerability. The attack complexity is low, as it does not require any special conditions to be met.
No special privileges are needed to exploit this vulnerability, and user interaction is required to trigger the overflow. The impacts on confidentiality, integrity, and availability are all significant, making this a critical vulnerability for affected systems.
Risk & Impact Analysis
Real-world deployment risk includes the potential for attackers to execute arbitrary code, leading to complete system compromise. Organizations using GNOME GdkPixbuf versions before 2.42.8 should be particularly concerned, especially on 32-bit systems where the overflow is more easily exploitable.
The blast radius could be significant, affecting not only the system on which GdkPixbuf is installed but potentially all interconnected systems. Given the CVSS score of 7.8 and the high potential for exploitation, organizations should address this vulnerability in their priority patch cycle.
