CVE-2026-108093— Gimp: gimp: denial of service via null pointer dereference in xcf simulation parasite loading

Quick assessment

Affected
Red Hat Red Hat Enterprise Linux 10
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

发现 GIMP 中存在一个漏洞。XCF 加载器在处理 image-simulation-intent 和 image-simulation-bpc 元数据（parasites）时，未在解引用之前验证元数据是否存在。通过打开一个经过精心构造的、包含零大小模拟元数据的 XCF 文件，可能导致空指针解引用，从而引发 GIMP 应用程序崩溃。

Vulnerability Title
Gimp: gimp: denial of service via null pointer dereference in xcf simulation parasite loading
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in GIMP. The XCF loader processes image-simulation-intent and image-simulation-bpc parasites without ensuring the parasite data is present before dereferencing it. Opening a specially crafted XCF file with a zero-size simulation parasite can cause a NULL pointer dereference and crash the GIMP application.
