CVE-2026-3284 identifies an integer overflow vulnerability in the libvips image processing library, version 8.19.0. The vulnerability exists in the function vips_extract_area_build within the source file libvips/conversion/extract.c. The issue is caused by improper validation or manipulation of the extract_area argument, which leads to an integer overflow condition. This overflow can result in memory corruption or unexpected behavior during image extraction operations. The attack vector is local, requiring the attacker to have local access with low privileges (PR:L) but no user interaction or elevated privileges are necessary. The vulnerability does not affect confidentiality, integrity, or availability directly but could be leveraged as part of a larger attack chain to cause denial of service or potentially execute arbitrary code depending on the context of use. The vulnerability has a CVSS 4.8 (medium) rating, reflecting limited impact and exploitation complexity. A patch identified by commit 24795bb3d19d84f7b6f5ed86451ad556c8f2fe70 has been released to fix the issue. No known exploits have been reported in the wild, but the exploit code has been made public, increasing the risk of future exploitation. Organizations using libvips 8.19.0, especially in local or embedded environments, should apply the patch promptly to prevent exploitation.

The integer overflow vulnerability in libvips 8.19.0 can lead to memory corruption, which may cause application crashes or unpredictable behavior in software relying on libvips for image processing. While the vulnerability requires local access and low privileges, it could be exploited by malicious insiders or attackers who have gained limited access to a system. The impact on confidentiality and integrity is limited unless combined with other vulnerabilities or attack techniques. Availability could be affected if the overflow leads to denial of service conditions. Since libvips is widely used in image processing pipelines, content management systems, and various applications, affected systems could experience service disruptions or instability. The exploitability is moderate, and although no active exploitation is reported, the public availability of exploit code increases the risk. Organizations relying on libvips in development, production, or embedded environments should consider this vulnerability a medium risk that warrants timely remediation.

To mitigate CVE-2026-3284, organizations should immediately apply the official patch identified by commit 24795bb3d19d84f7b6f5ed86451ad556c8f2fe70 to all systems running libvips version 8.19.0. If patching is not immediately feasible, restrict local access to systems running vulnerable versions to trusted users only and monitor for unusual activity. Conduct code reviews and testing of any custom software that uses libvips to ensure it handles image extraction safely. Employ runtime protections such as memory corruption mitigations (e.g., ASLR, DEP) to reduce exploitation impact. Additionally, maintain updated inventories of software dependencies to quickly identify and remediate vulnerable versions. Finally, consider upgrading to newer libvips versions beyond 8.19.0 where this vulnerability is fixed and ensure continuous monitoring for any emerging exploit attempts.
