Pillow vulnerability can cause write buffer overflow on BCn encoding

CVE-2025-48379 / GHSA-xg8h-j46f-w952

More information

Details

There is a heap buffer overflow when writing a sufficiently large (>64k encoded with default settings) image in the DDS format due to writing into a buffer without checking for available space.

This only affects users who save untrusted data as a compressed DDS image.

• Unclear how large the potential write could be. It is likely limited by process segfault, so it's not necessarily deterministic. It may be practically unbounded.
• Unclear if there's a restriction on the bytes that could be emitted. It's likely that the only restriction is that the bytes would be emitted in chunks of 8 or 16.

This was introduced in Pillow 11.2.0 when the feature was added.

Pillow affected by out-of-bounds write when loading PSD images

CVE-2026-25990 / GHSA-cfh3-3jmp-rvhc

More information

Details

Impact

An out-of-bounds write may be triggered when loading a specially crafted PSD image. Pillow >= 10.3.0 users are affected.

Patches

Pillow 12.1.1 will be released shortly with a fix for this.

Workarounds

Image.open() has a formats parameter that can be used to prevent PSD images from being opened.

References

Pillow 12.1.1 will add release notes at https://pillow.readthedocs.io/en/stable/releasenotes/index.html

FITS GZIP decompression bomb in Pillow

CVE-2026-40192 / GHSA-whj4-6x5x-4v2j

More information

Details

Impact

Pillow did not limit the amount of GZIP-compressed data read when decoding a FITS image, making it vulnerable to decompression bomb attacks. A specially crafted FITS file could cause unbounded memory consumption, leading to denial of service (OOM crash or severe performance degradation).

Patches

The amount of data read is now limited to the necessary amount.
Fixed in Pillow 12.2.0 (PR #​9521).

Workarounds

Avoid Pillow >= 10.3.0, < 12.2.0
Only open specific image formats, excluding FITS.

Pillow has a heap buffer overflow with nested list coordinates

CVE-2026-42309 / GHSA-5xmw-vc9v-4wf2

More information

Details

Passing nested lists as coordinates to APIs that accept coordinates such as ImagePath.Path, ImageDraw.ImageDraw.polygon and ImageDraw.ImageDraw.line could cause a heap buffer overflow, as nested lists were recursively unpacked beyond the allocated buffer. Coordinate lists are now validated to contain exactly two numeric coordinates. This was introduced in Pillow 11.2.1.

Pillow has an OOB Write with Invalid PSD Tile Extents (Integer Overflow)

CVE-2026-42311 / GHSA-pwv6-vv43-88gr

More information

Details

Impact

Processing a malicious PSD file could lead to memory corruption, potentially resulting in a crash or arbitrary code execution.

Patches

Patched version: 12.2.0

Pillow 12.1.1 addressed CVE-2026-25990 by adding checks for tile extents in PSD image decoding/encoding to prevent an out-of-bounds write. However, the bounds checks computed tile extent sums using types susceptible to integer overflow, meaning a PSD image with carefully chosen tile dimensions could produce values that wrap around and bypass the checks, still triggering an out-of-bounds write in src/decode.c and src/encode.c. The fix avoids adding extents together before comparison.

Workarounds

Use any version but affected versions: >= 10.3.0, < 12.2.0

Pillow has an integer overflow when processing fonts

CVE-2026-42308 / GHSA-wjx4-4jcj-g98j

More information

Details

If a font advances for each glyph by an exceeding large amount, when Pillow keeps track of the current position, it may lead to an integer overflow. This has been fixed.

Pillow has a PDF Parsing Trailer Infinite Loop (DoS)

CVE-2026-42310 / GHSA-r73j-pqj5-w3x7

More information

Details

Impact

An attacker can supply a malicious PDF that causes the process to hang indefinitely, consuming 100% CPU and making the application unresponsive.

Patches

Patched version: 12.2.0.

PdfParser (introduced in Pillow 4.2.0) follows Prev pointers in PDF trailers to read cross-reference sections. If a
trailer's Prev pointer references an offset that has already been processed — either pointing to itself or forming a
longer cycle — the parser enters an infinite loop. Pillow now tracks previously processed trailer offsets and raises an
error if a cycle is detected.

Workarounds

Use any version but the affected versions: >= 4.2.0, < 12.2.0
