DescriptionCVE.org

GIMP PSD File Parsing Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the parsing of PSD files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28807.

AnalysisAI

Integer overflow in GIMP PSD file parser enables remote code execution when users open malicious PSD files. Affects GIMP installations across platforms. Exploitation requires user interaction (opening crafted file). Attacker achieves arbitrary code execution in application context with high confidentiality, integrity, and availability impact. Publicly available exploit code exists. Insufficient validation of user-supplied data during buffer allocation causes overflow, allowing memory corruption and code execution.

Technical ContextAI

Integer overflow occurs during PSD file parsing before buffer allocation (CWE-190). Parser fails to validate size parameters from user-controlled file data, causing arithmetic overflow when calculating allocation size. Overflow results in undersized buffer, leading to memory corruption exploitable for code execution. Tracked as ZDI-CAN-28807.

RemediationAI

Vendor-released patch available via upstream fix commit 00afdabdadeb5457fd897878b1e5aebc3780af10 in GIMP GitLab repository; released patched version not independently confirmed at time of analysis. SUSE users apply security update SUSE-SU-2026:1193 immediately via zypper update. Until patched version deployed, avoid opening PSD files from untrusted sources. Consider disabling PSD import plugin if GIMP version cannot be immediately updated. Monitor vendor advisory at https://gitlab.gnome.org/GNOME/gimp/-/commit/00afdabdadeb5457fd897878b1e5aebc3780af10 and ZDI advisory https://www.zerodayinitiative.com/advisories/ZDI-26-217/ for version-specific guidance. Implement application whitelisting and sandboxing to limit exploitation impact.
