CVE-2026-51235
Description
A flaw was found in LibRaw, an open-source library for processing raw image files. This vulnerability is a buffer overflow, which occurs in the stretch() and fuji_rotate() functions. A buffer overflow can allow an attacker to overwrite memory, potentially leading to a denial of service or the execution of unauthorized code.
Statement
This Important flaw in LibRaw, a library for processing raw image files, is a buffer overflow in the stretch() and fuji_rotate() functions. Successful exploitation requires a local attacker to trick a user into processing a specially crafted raw image file, which could lead to arbitrary code execution or a denial of service. Red Hat Enterprise Linux 9 is affected, while Red Hat Enterprise Linux 8 and older versions are not vulnerable as they ship with older, unaffected versions of LibRaw or do not contain the vulnerable code.
Mitigation
Mitigation for this issue involves avoiding the processing of untrusted raw image files. As this vulnerability resides within a library, there are no direct configuration or operational controls to disable the vulnerable functions without impacting applications that rely on LibRaw for image processing.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of the product's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the product into an infinite loop.
