Low risk43th percentile - higher than 43% of all known CVEs
Summary
A flaw was found in GIMP's PSD file format plugin. This vulnerability, an unsigned integer underflow in the `block_rem` variable, occurs when a user opens a specially crafted `.psd` image file. The underflow leads to parser confusion, enabling an attacker to inject arbitrary data as layer resource blocks. This can ultimately result in arbitrary code execution.
Risk Assessment
An attacker can execute malicious code on the victim's system, potentially leading to full system compromise and data theft.
Recommendation
Update GIMP to the latest patched version. Do not open .psd files from untrusted sources.
