Vulnerability Details
The official description of CVE-2023-48161 states that it is a buffer overflow vulnerability in GifLib Project GifLib v.5.2.1. This vulnerability allows a local attacker to obtain sensitive information via the DumpSCreen2RGB function in gif2rgb.c.
The CVSS score for this vulnerability is 7.1, classified as high severity due to a low attack complexity and low privileges required for exploitation. The attack vector is local, meaning that an attacker must have local access to the vulnerable system to exploit this vulnerability. The impact on confidentiality is high, while integrity is not impacted, and availability is also high.
The affected product is GifLib version 5.2.1, published on November 22, 2023. The vulnerability is categorized under CWE-787, which corresponds to improper control of length in a buffer.
Technical Analysis
The root cause of this vulnerability is a buffer overflow, which occurs when data exceeds a buffer's storage capacity. In this case, the vulnerability is related to the DumpSCreen2RGB function in gif2rgb.c, which does not adequately check the size of input data, leading to potential overwriting of adjacent memory.
The attack vector is local, meaning that exploitation requires an attacker to have access to the vulnerable system. The attack complexity is low, with low privileges required to exploit the vulnerability. User interaction is not required for exploitation, allowing attackers to leverage this vulnerability without additional steps.
The confidentiality impact is high, as sensitive information can be accessed by the attacker. Integrity is unaffected, and availability impact is also high, risking potential denial of service due to the overflow.
Risk & Impact Analysis
Organizations utilizing GifLib Project need to recognize the potential risks associated with CVE-2023-48161. The ability for local attackers to exploit this buffer overflow vulnerability can lead to unauthorized access to sensitive data, which poses a significant threat to organizational security and compliance.
The blast radius for this vulnerability is considerable, particularly in environments where GifLib is extensively used for image processing. The urgency for organizations to address this vulnerability is high, as it could facilitate data breaches or other malicious activities if left unremediated.
Given the CVSS score of 7.1 and the lack of known exploits, organizations should still act swiftly to apply necessary patches and strengthen their security posture to prevent any potential exploitation in the future.
