CVE-2026-92248

Gimp: integer overflow when generating a thumbnail preview for a psd file

A flaw was found in the file-psd plugin in GIMP. When generating a thumbnail preview for a specially crafted PSD (Photoshop Document) image file, an integer overflow occurs during the multiplication of values from an embedded JPEG header. This leads to an undersized heap allocation, resulting in a heap-based buffer overflow when the image data is decoded. This buffer overflow corrupts adjacent heap objects, allowing for a controlled memory write that can result in an application crash or arbitrary code execution.

Gimp: gimp: out-of-bounds write in lighting effects plugin via crafted preset file

A flaw was found in GIMP. When processing a specially crafted lighting preset file, the Lighting Effects filter does not properly validate the number of light sources. This can lead to an out-of-bounds write, corrupting memory. An attacker could exploit this by convincing a user to open a malicious preset file, potentially causing a crash or enabling arbitrary code execution.

Gimp: stack vla size underflow denial of service in seattle

A flaw was found in the Seattle FilmWorks plugin in GIMP. When processing a specially crafted SFW image file, the plugin allocates a Variable-Length Array (VLA) on the stack without integer overflow checks, causing an unbounded stack allocation. This issue leads to an application crash, resulting in a denial of service.

CVE-2026-59089

Gimp: gimp: denial of service via integer overflow in playstation tim loader

A flaw was found in GIMP. The PlayStation TIM loader, responsible for handling PlayStation image files, incorrectly calculates the size of the Color Look-Up Table (CLUT) due to an integer overflow. This occurs when multiplying num_colors and num_cluts, both 16-bit unsigned short integers, resulting in a value exceeding the maximum integer limit. An attacker could exploit this by providing a specially crafted image file, leading to undefined behavior and causing the GIMP plug-in to abort, effectively resulting in a denial of service.

CVE-2026-58380

Gimp: gimp: stack buffer overflow in pnmscanner_gettoken()

A flaw was found in GIMP's PNM file format parser. When parsing a specially crafted PNM file, the pnmscanner_gettoken() function writes a null terminator one byte past the end of a stack-allocated buffer due to an off-by-one error in the loop boundary check. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution.

Gimp: gimp:memory disclosure and denial of service via specially crafted pcx image

A flaw was found in GIMP. This issue is a heap buffer over-read in GIMP PCX file loader due to an off-by-one error. A remote attacker could exploit this by convincing a user to open a specially crafted PCX image. Successful exploitation could lead to out-of-bounds memory disclosure and a possible application crash, resulting in a Denial of Service (DoS).

Gimp: gimp: file-pvr plug-in pvr file parsing integer overflow heap-based buffer overflow vulnerability

A flaw was found in GIMP. An integer overflow occurs in the file-pvr plug-in when calculating memory buffer sizes for image dimensions. By tricking a user into opening or previewing a specially crafted PowerVR (.pvr) file, an attacker can trigger a heap-based buffer overflow, potentially leading to arbitrary code execution or a Denial of Service (DoS) via an application crash.

CVE-2026-96543

gimp: gimp: out-of-bounds heap write when loading non-square PVR images

An out-of-bounds heap write flaw was found in GIMP's PVR image loader. When loading a crafted non-square PVR texture, pvr_decode_twiddle() can write attacker-controlled pixel data beyond the end of a correctly allocated heap buffer because the destination offset is not bounds-checked. A local attacker can exploit this by convincing a user to open a malicious PVR image, potentially causing arbitrary code execution in the file-pvr plug-in process.

CVE-2026-96544

gimp: gimp: integer overflow in the PVR image loader leads to an out-of-bounds heap read

An integer overflow flaw was found in GIMP's PVR image loader. When a user opens a crafted PVR image, unchecked multiplication of attacker-controlled dimensions in pvr_decode_rect() can result in an undersized heap allocation followed by an out-of-bounds read. This may disclose adjacent heap contents through the decoded image or crash the file-pvr plug-in.

gimp: XWD plugin color map heap-based buffer overflow

Heap-based buffer overflow in the read_xwd_cols function in file-xwd.c in the X Window Dump (XWD) plug-in in GIMP 2.6.9 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an X Window System (XWD) image dump with more colors than color map entries.

Integer overflow in the load_image function in file-xwd.c in the X Window Dump (XWD) plug-in in GIMP 2.6.9 and earlier, when used with glib before 2.24, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large color entries value in an X Window System (XWD) image dump.
