CVE-2026-6491: Heap-based Buffer Overflow in libvips
A security vulnerability has been detected in libvips up to 8.18.2. The affected element is the function im_minpos_vec of the file libvips/deprecated/vips7compat.c of the component nip2 Handler. Such manipulation of the argument n leads to heap-based buffer overflow. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. The vendor confirms that they will "be removing the deprecated area in libvips 8.19".
AI Analysis
Technical Summary
This vulnerability in libvips (up to version 8.18.2) is a heap-based buffer overflow triggered by improper handling of the argument 'n' in the im_minpos_vec function located in libvips/deprecated/vips7compat.c, part of the nip2 Handler component. Exploitation requires local access and can lead to memory corruption. The vendor has announced the removal of the deprecated code area containing this function in the upcoming libvips 8.19 release. There is no current official patch or remediation level provided.
Potential Impact
Successful exploitation of this vulnerability can cause heap-based buffer overflow, potentially leading to application crashes or memory corruption. Since exploitation requires local access and no remote vector is indicated, the impact is limited to local users with some level of privilege. No known exploits are currently reported in the wild.
Mitigation Recommendations
No official patch or fix is currently available. The vendor plans to remove the deprecated vulnerable code in libvips 8.19. Until then, users should restrict local access to trusted users only and consider upgrading to libvips 8.19 once released to eliminate the vulnerable code.
