CVE-2026-35590
Description
A flaw was found in libvips. The EXIF decoder did not properly verify the range of EXIF tag groups, which could lead to a null pointer dereference. A local user could exploit this by providing specially crafted EXIF data, causing the application to crash and resulting in a denial of service.
Statement
This Moderate severity flaw in libvips' EXIF decoder allows a local attacker to trigger a denial of service. By providing a specially crafted image file containing malformed EXIF data, an application utilizing libvips can crash due to a null pointer dereference. This impact is limited to scenarios where untrusted image input is processed.
Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Crash, Exit, or Restart
NULL pointer dereferences usually result in the failure of the process unless exception handling (on some platforms) is available and implemented. Even when exception handling is being used, it can still be very difficult to return the software to a safe state of operation.
Integrity,Confidentiality
Technical Impact: Execute Unauthorized Code or Commands; Read Memory; Modify Memory
In rare circumstances, when NULL is equivalent to the 0x0 memory address and privileged code can access it, then writing or reading memory is possible, which may lead to code execution.
