Vulnerability from csaf_redhat - Published: 2026-05-04 01:51 - Updated: 2026-05-05 20:33Summary
Red Hat Security Advisory: LibRaw security update
Severity
Important
Notes
Topic: An update for LibRaw is now available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: LibRaw is a library for reading RAW files obtained from digital photo cameras (CRW/CR2, NEF, RAF, DNG, and others).
Security Fix(es):
* LibRaw: LibRaw: Memory Corruption via Malicious File Processing (CVE-2026-24660)
* LibRaw: LibRaw: Arbitrary code execution via heap-based buffer overflow in lossless JPEG loading (CVE-2026-21413)
* LibRaw: LibRaw: Arbitrary code execution via specially crafted image file (CVE-2026-20889)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

A flaw was found in LibRaw, a library used for processing raw image files. This vulnerability, a heap-based buffer overflow, exists within the x3f_thumb_loader functionality. A remote attacker could exploit this by tricking a user into opening a specially crafted malicious file. Successful exploitation could lead to arbitrary code execution, giving the attacker full control over the affected system.
7.5 (High)
Vendor Fix
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2026:13284
Workaround
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
A flaw was found in LibRaw. A heap-based buffer overflow vulnerability exists in the `lossless_jpeg_load_raw` functionality. A remote attacker can exploit this by providing a specially crafted malicious file. This can lead to arbitrary code execution, allowing the attacker to take control of the affected system, or cause a denial of service (DoS).
