A vulnerability classified as problematic was found in Vim up to version 9.1.1096. This vulnerability affects unknown code of the file src/main.c. The manipulation of the argument --log leads to memory corruption. It is possible to launch the attack on the local host. Upgrading to version 9.1.1097 is able to address this issue. The patch is identified as c5654b84480822817bb7b69ebc97c174c91185e9. Organizations should prioritize patching immediately.
This vulnerability has a CVSS score of 2.4, indicating a low severity level. However, it is essential to assess the risk to organizations. For this vulnerability, the potential for exploitation exists primarily on local hosts with low attack complexity. Organizations should address this vulnerability in their priority patch cycle.
Although the vulnerability does not currently have a known exploit or public proof of concept, the risk remains due to its nature and potential for memory corruption. Keeping software components up to date is crucial to maintaining security posture.
Upgrading to the patched version of Vim is the most effective mitigation strategy. Organizations should also consider implementing monitoring solutions to detect any signs of exploitation attempts.
Vulnerability Details
The official description of the vulnerability states that it allows for memory corruption through the manipulation of the --log argument in Vim. The vulnerability has been classified under CWE-119, which pertains to improper restriction of operations within the bounds of a memory buffer.
The vulnerability was published on February 12, 2025, and the affected versions are all versions prior to 9.1.1097. Organizations running vulnerable versions need to act.
Technical Analysis
The root cause of this vulnerability is the improper handling of the --log argument, which leads to memory corruption. The attack vector is local, which means an attacker must have access to the local machine to exploit this vulnerability. The attack complexity is low, as it does not require a high level of skill or extensive resources to exploit.
The privileges required to exploit this vulnerability are low, meaning that any user with access to the system could potentially exploit it. User interaction is passive, as the attack does not require any action from the user. The impact on confidentiality and integrity is none, but the availability impact is low, as it may lead to local crashes or similar issues.
Risk & Impact Analysis
Risk to organizations includes potential disruptions to local operations due to memory corruption, leading to crashes or unintended behaviors in Vim. The potential for exploitation is limited to local environments, but the consequences of a successful attack could affect productivity.
Organizations should assess their deployment of Vim and implement the latest patches as soon as possible. Given the low severity of this vulnerability, it might not be at the top of the priority list, but it should not be overlooked due to the possibility of local exploitation.
The urgency for remediation should be categorized as moderate. Scheduling remediation during the next patch cycle is advisable to mitigate any potential risks.
