CVE-2025-48797: Gimp: multiple heap buffer overflows in tga parser

A flaw was found in GIMP when processing certain TGA image files. If a user opens one of these image files that has been specially crafted by an attacker, GIMP can be tricked into making serious memory errors, potentially leading to crashes and causing a heap buffer overflow.

Security readout for executives and security teams

Plain-English summary

CVE-2025-48797 is a high-severity GIMP image-parsing flaw. A malicious TGA file can trigger heap memory corruption when opened by a user, causing crashes and potentially broader compromise under the CVSS impact model. This is most urgent where staff process images from untrusted sources.

Executive priority

Treat this as a prompt patching item for image-handling workstations, not a network-wide emergency. The attack needs user interaction, but successful memory corruption in a desktop application can still create meaningful business risk.

Technical view

The flaw is reported as multiple heap buffer overflows in GIMP's TGA parser, classified as CWE-122. The CVSS 3.1 vector is local, low complexity, low privileges, and requires user interaction, with high confidentiality, integrity, and availability impact ratings.

Likely exposure

Exposure is likely on systems with affected Red Hat Enterprise Linux GIMP packages installed, especially RHEL 7 ELS, RHEL 8 AppStream gimp:2.8 streams, and RHEL 9 GIMP packages listed in the source bundle.

Exploitation context

The sources do not show CISA KEV listing or active exploitation evidence. Exploitation requires persuading a user to open a specially crafted TGA image in GIMP, so email, downloads, shared drives, and design workflows are plausible delivery paths.

Researcher notes

Evidence supports a TGA parser heap overflow in GIMP with high CVSS impact. The bundle does not provide exploit proof, patch commit details, or complete non-Red-Hat version mapping. Avoid assuming active exploitation or specific exploitability beyond the cited CVSS and description.

Mitigation direction

  • Apply the relevant Red Hat security advisory updates for affected RHEL releases.
  • Check upstream GIMP and distribution vendor guidance for non-Red Hat systems.
  • Limit opening TGA files from untrusted sources until systems are updated.
  • Use attachment filtering or sandboxed image handling for high-risk workflows.
  • Remove GIMP from systems where it is not operationally required.

Validation and detection

  • Inventory endpoints and servers for installed GIMP packages and versions.
  • Map installed packages to the affected RHEL products and versions in the bundle.
  • Verify applicable RHSA updates are installed through standard package records.
  • Confirm security tools flag CVE-2025-48797 as remediated after patching.
  • Review logs for unusual GIMP crashes after opening image files.
