CVE-2026-58379

A flaw was found in GIMP's Paint Shop Pro (PSP) file format parser. This heap buffer overflow vulnerability allows a remote attacker to cause arbitrary code execution or a denial of service (DoS) by tricking a user into opening a specially crafted PSP image file. The vulnerability occurs because the software incorrectly calculates buffer sizes when processing low bit-depth images, leading to an overwrite of adjacent memory.

Executive briefing

The source record describes: A flaw was found in GIMP's Paint Shop Pro (PSP) file format parser. This heap buffer overflow vulnerability allows a remote attacker to cause arbitrary code execution or a denial of service (DoS) by tricking a user into opening a specially crafted PSP image file. The vulnerability occurs because the software incorrectly calculates buffer sizes when processing low bit-depth images, leading to an overwrite of adjacent memory. The practical risk depends on whether an affected product/version is present, reachable and configured in an exploitable way. Review the affected-product evidence and linked vendor advisories before assigning exposure status.

Assessment: Potential exposure only — validate the installed product, exact version, configuration and vendor applicability before treating an asset as confirmed vulnerable.

Evidence confidence: Moderate Evidence-derived, not an exploitability verdict

Technical explanation & impact

The technical mechanism is not expanded beyond the source description unless a referenced advisory supplies additional evidence. Read the linked vendor/CERT advisories for root-cause detail.

Potential impact must be interpreted from the published CVSS impact metrics and the affected component. A CVSS impact score is not proof that a particular asset is exploitable.

Remediation & validation

  1. Identify exposure by comparing the affected product and version ranges with your asset inventory, SBOM and externally exposed services.
  2. Review the linked vendor security advisory or patch notes. Upgrade to a vendor-confirmed fixed release; do not infer a fixed version from the CVE description.
  3. Until patched, consider restricting network access or disabling the affected feature where operationally safe. These are temporary controls, not a substitute for a vendor fix.
  4. Validate the remediation with a version check and vulnerability rescan, then retain change evidence.

No fixed version is displayed unless it is explicitly established by a vendor advisory. Follow the vendor's release notes for exact product and branch applicability.
