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

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...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write in the setimage functions in encode.c and decode.c, which are exploitable via Image.open. An attacker can execute arbitrary code by supplying a malicious PSD image file with tile dimensions that trigger integer...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop in trailer handling in PIL/PdfParser.py. An attacker can cause the application to consume excessive CPU by supplying a malicious file that creates a cyclic reference in the trailer's Prev pointer. Remediation Upgrade pillo...

Pillow has a PDF Parsing Trailer Infinite Loop (DoS)

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 ...

GHSA-R73J-PQJ5-W3X7 Pillow has a PDF Parsing Trailer Infinite Loop (DoS)

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 ...

GHSA-WJX4-4JCJ-G98J Pillow has an integer overflow when processing fonts

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...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound. An attacker can cause unexpected behavior by supplying a font where each glyph advances by an excessively large amount. Remediation Upgrade pillow to version 12.2.0 or higher. References - GitHub Advisory...

Heap-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Heap-based Buffer Overflow in ImagePath.Path, ImageDraw.ImageDraw.polygon, and ImageDraw.ImageDraw.line, all of which accept nested coordinates as input. An attacker can cause denial of service by supplying nested lists as coordinates,...

Pillow has a heap buffer overflow with nested list coordinates

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...
