CVE-2022-35086: n/a in n/a
SWFTools commit 772e55a2 was discovered to contain a segmentation violation via /multiarch/memmove-vec-unaligned-erms.S.
AI Analysis
Technical Summary
CVE-2022-35086 is a medium-severity vulnerability identified in SWFTools, specifically linked to a segmentation violation caused by the code in /multiarch/memmove-vec-unaligned-erms.S. This vulnerability is categorized under CWE-787, which refers to out-of-bounds write errors. The segmentation violation indicates that the software attempts to access memory outside the bounds of allocated buffers, potentially leading to application crashes or denial of service. The vulnerability has a CVSS 3.1 base score of 5.5, reflecting a medium severity level. The attack vector is local (AV:L), meaning an attacker needs local access to the system to exploit the flaw. The attack complexity is low (AC:L), no privileges are required (PR:N), but user interaction is necessary (UI:R). The scope is unchanged (S:U), and the impact affects availability only (A:H), with no impact on confidentiality or integrity. No known exploits are reported in the wild, and no patches or vendor information are currently available. The vulnerability arises from unsafe memory operations in a low-level assembly routine related to memory movement, which can cause segmentation faults and disrupt service availability.
Potential Impact
For European organizations, the primary impact of this vulnerability is the potential for denial of service conditions on systems running SWFTools or components that include the vulnerable memmove implementation. Since the attack requires local access and user interaction, the risk is somewhat limited to insider threats or scenarios where an attacker has already gained some level of access. However, in environments where SWFTools is used for document processing or PDF manipulation, such as publishing houses, government agencies, or media companies, exploitation could disrupt critical workflows. The lack of confidentiality or integrity impact reduces the risk of data breaches, but availability interruptions could affect business continuity. Organizations relying on automated document processing pipelines that incorporate SWFTools might experience service outages or crashes, impacting operational efficiency.
Mitigation Recommendations
Given the local attack vector and requirement for user interaction, mitigation should focus on limiting local access and controlling user privileges. Organizations should: 1) Restrict access to systems running SWFTools to trusted users only and enforce strict user authentication and authorization policies. 2) Monitor and audit local user activities to detect suspicious behavior that might lead to exploitation attempts. 3) Isolate systems running SWFTools from untrusted networks and users to reduce exposure. 4) Implement application whitelisting and endpoint protection to prevent execution of unauthorized code. 5) Regularly update and patch SWFTools or related components as vendor fixes become available. 6) Consider replacing or sandboxing SWFTools in critical environments to contain potential crashes. 7) Educate users about the risks of interacting with untrusted files or applications that might trigger the vulnerability.
