libwebp: OOB write in BuildHuffmanTable

CVE-2023-4863 / GHSA-j7hp-h8jx-5ppr

More information

Details

Heap buffer overflow in libwebp allow a remote attacker to perform an out of bounds memory write via a crafted HTML page.

Severity

CVSS Score: 8.8 / 10 (High)
Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

Pillow Denial of Service vulnerability

CVE-2023-44271 / GHSA-8ghj-p4vj-mr35

More information

Details

An issue was discovered in Pillow before 10.0.0. It is a Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.

Severity

CVSS Score: 8.7 / 10 (High)
Vector String: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N

Arbitrary Code Execution in Pillow

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

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)
Vector String: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

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.

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 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
