Attack profile from CVSS 3.1 · CNA. Fix status from CNA and Red Hat. Impact type from CWE-476.
Summary
A flaw in GIMP's XCF loader handles the image-simulation-intent and image-simulation-bpc parasites without checking that their data is present before dereferencing it. Opening a specially crafted XCF file with a zero-size simulation parasite causes a NULL pointer dereference (CWE-476) that crashes the GIMP application. Red Hat rates the issue Moderate. The CVSS 3.1 base score is 5.5 (MEDIUM), and CISA's SSVC data shows no known exploitation, not automatable, and partial technical impact.

Remediation
The sources list no fixed version for Red Hat Enterprise Linux 6, 7, 8, 9 or 10. Red Hat plans no fix for RHEL 6 and 7, and lists none as available for RHEL 8, 9 and 10. Until a fixed GIMP package ships, avoid opening XCF files from untrusted sources.
