CVE-2026-50291
Description
A flaw was found in OpenImageIO, a toolset for image file manipulation. A remote attacker could exploit this vulnerability by providing a specially crafted BMP (Bitmap) image file. Processing this malicious file can lead to an invalid read operation during image decoding, causing the application to crash. This results in a denial of service (DoS), making the affected application unavailable.
Statement
Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery. For more information about this vulnerability and the products it affects, please see the linked references.
Mitigation
To mitigate this issue, avoid processing untrusted BMP image files with applications that utilize the OpenImageIO library. If such processing is unavoidable, consider implementing sandboxing mechanisms for applications handling untrusted image input to limit the potential impact of a denial of service.
Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Memory
An attacker could get secret values such as cryptographic keys, PII, memory addresses, or other information that could be used in additional attacks.
Confidentiality
Technical Impact: Bypass Protection Mechanism
Out-of-bounds memory could contain memory addresses or other information that can be used to bypass ASLR and other protection mechanisms in order to improve the reliability of exploiting a separate weakness for code execution.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
An attacker could cause a segmentation fault or crash by causing memory to be read outside of the bounds of the buffer. This is especially likely when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string.
Other
Technical Impact: Varies by Context
The read operation could produce other undefined or unexpected results.
