PYSEC-2023-175

More information

Details

Pillow versions before v10.0.1 bundled libwebp binaries in wheels that are vulnerable to CVE-2023-5129 (previously CVE-2023-4863). Pillow v10.0.1 upgrades the bundled libwebp binary to v1.3.2.

Arbitrary Code Execution in Pillow

BIT-pillow-2023-50447 / CVE-2023-50447 / GHSA-3f63-hfp8-52jq

More information

Details

Pillow through 10.1.0 allows PIL.ImageMath.eval Arbitrary Code Execution via the environment parameter, a different vulnerability than CVE-2022-22817 (which was about the expression parameter).

Severity

CVSS Score: 9.3 / 10 (Critical)

Pillow buffer overflow vulnerability

BIT-pillow-2024-28219 / CVE-2024-28219 / GHSA-44wm-f244-xhp3

More information

Details

In _imagingcms.c in Pillow before 10.3.0, a buffer overflow exists because strcpy is used instead of strncpy.

Severity

CVSS Score: 7.3 / 10 (High)

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

Resources

Fix: https://github.com/python-pillow/Pillow/pull/9519

Severity

CVSS Score: 5.1 / 10 (Medium)
Vector String: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N

Pillow has an integer overflow when processing fonts

CVE-2026-42308 / ECHO-784c-565e-18bc / 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.
