CVE-2026-78475: A flaw was found in the file-pix (ESM) plugin in GIMP

Routine

MEDIUM 6.1WATCHLISTUPGRADEMITIGATE

CVE-2026-78475 is a medium-severity flaw (CVSS 6.1) affecting gimp, enterprise linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A flaw was found in the file-pix (ESM) plugin in GIMP. When processing a specially crafted PIX image file, the plugin allocates a Variable-Length Array (VLA) on the stack without proper bounds checking, causing an unbounded stack allocation followed by a 21-byte stack over-read. This can result in a denial of service due to stack exhaustion and a limited information disclosure of stack memory contents into an intermediate file.

2026-10-12 22:10 UTCUpdated Record last modified

gimp gimp UPGRADE

Affected: >= 3.0.0 and <= 3.3.1

Fixed in: newer than 3.3.1

Safe to downgrade to: a release before 3.0.0

1. Check installed version

apt-cache policy gimp || rpm -q gimp || gimp --version

2. UPGRADE to newer than 3.3.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade gimp

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade gimp

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 3.0.0 (Debian / Ubuntu)

apt-cache madison gimp sudo apt install gimp=<VERSION_BEFORE_3.0.0> sudo apt-mark hold gimp

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list gimp sudo dnf downgrade gimp-<VERSION_BEFORE_3.0.0> sudo dnf versionlock add gimp

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.

redhat enterprise linux MITIGATE

Affected: 9.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 9.0

Check your OS release

cat /etc/os-release; uname -r

Debian / Ubuntu

sudo apt update && sudo apt full-upgrade

RHEL / Amazon Linux / Fedora

sudo dnf upgrade --refresh

Windows

Install the latest cumulative update from Windows Update

If no patch exists yet

OS downgrades are not safe. Apply the vendor mitigation from the advisory and restrict exposure.
