CVE-2026-59205 (GCVE-0-2026-59205)

Vulnerability from nvd – Published: 2026-07-14 15:48 – Updated: 2026-07-14 17:31

Title

Pillow: Controlled heap out-of-bounds write in `ImageCmsTransform.apply()` via output mode mismatch

Summary

Pillow is a Python imaging library. Prior to 12.3.0, Pillow's ImageCms.ImageCmsTransform.apply(im, imOut) API can trigger controlled native heap corruption when the caller supplies an output image whose mode does not match the transform's declared output mode. This issue is fixed in version 12.3.0.

Severity

7.5 (High)

CVE-2026-59204 (GCVE-0-2026-59204)

Vulnerability from nvd – Published: 2026-07-14 15:38 – Updated: 2026-07-14 15:38

Title

Pillow JPEG2000 tiled decode retains a growing scratch buffer and can be used for denial of service

Summary

Pillow is a Python imaging library. From 8.2.0 through 12.2.0, src/libImaging/Jpeg2KDecode.c accumulates total_component_width across every tile in a JPEG2000 image instead of recomputing it per tile, allowing a crafted tiled JPEG2000 file to force substantially higher transient memory usage and trigger out-of-memory failures during decoding. This issue is fixed in version 12.3.0.

Severity

8.7 (High)

CVE-2026-59203 (GCVE-0-2026-59203)

Vulnerability from nvd – Published: 2026-07-14 15:43 – Updated: 2026-07-14 15:49

Title

Pillow EpsImagePlugin negative %%BeginBinary byte count causes infinite loop denial of service

Summary

Pillow is a Python imaging library. From 12.0.0 through 12.2.0, Pillow's EPS parser in PIL/EpsImagePlugin.py accepts a negative byte count in the %%BeginBinary directive, allowing a crafted EPS file to cause Image.open() to seek backwards to the same directive and parse it repeatedly in an infinite loop. This issue is fixed in version 12.3.0.

Severity

5.3 (Medium)

CVE-2026-59199 (GCVE-0-2026-59199)

Vulnerability from nvd – Published: 2026-07-14 15:42 – Updated: 2026-07-14 15:42

Title

Pillow: Heap out-of-bounds write `Image.paste()` / `Image.crop()` via signed coordinate overflow

Summary

Pillow is a Python imaging library. Prior to 12.3.0, Pillow public image coordinate APIs can trigger a native heap out-of-bounds write when given coordinates near the signed 32-bit integer limits in Image.paste(), Image.crop(), or Image.alpha_composite(). This issue is fixed in version 12.3.0.

Severity

7.5 (High)

CVE-2026-59198 (GCVE-0-2026-59198)

Vulnerability from nvd – Published: 2026-07-14 16:07 – Updated: 2026-07-14 19:55

Title

Pillow TGA RLE encoder can serialize up to ~57 KB of adjacent heap data into generated images

Summary

Pillow is a Python imaging library. From 5.2.0 until 12.3.0, Pillow's TGA RLE encoder reads past its packed row buffer when saving a mode 1 image with TGA RLE compression, allowing adjacent process heap bytes to be copied into the generated TGA file. This issue is fixed in version 12.3.0.

CVE-2026-59890 (GCVE-0-2026-59890)

Vulnerability from nvd – Published: 2026-07-08 16:02 – Updated: 2026-07-08 16:44

Title

setuptools: MANIFEST.in exclusion bypass in sdist via Unicode normalization collision (NFC/NFD) on macOS APFS/HFS+

Summary

setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python packages. Prior to 83.0.0, FileList applied MANIFEST.in exclude, global-exclude, recursive-exclude, and prune directives by matching compiled glob patterns against on-disk file names without Unicode normalization, so on macOS APFS or HFS+ an NFD file name could bypass an NFC exclusion rule and be packed into a source distribution. This issue is fixed in version 83.0.0.

Severity

6.1 (Medium)

CVE-2026-55798 (GCVE-0-2026-55798)

Vulnerability from nvd – Published: 2026-07-06 18:44 – Updated: 2026-07-07 15:19

Title

Pillow: WindowsViewer.get_command() OS command injection via unescaped shell path

Summary

Pillow is a Python imaging library. Prior to 12.3.0, WindowsViewer.get_command() constructed a cmd.exe shell command by directly embedding a file path into an f-string without escaping and passed the result to subprocess.Popen(..., shell=True), allowing shell metacharacters in the file path to inject arbitrary cmd.exe commands. This issue is fixed in version 12.3.0.

Severity

4.5 (Medium)

CVE-2026-55380 (GCVE-0-2026-55380)

Vulnerability from nvd – Published: 2026-07-06 18:50 – Updated: 2026-07-06 19:23

Title

Pillow GdImageFile decompression bomb protection bypass

Summary

Pillow is a Python imaging library. Prior to 12.3.0, PIL/GdImageFile.py GdImageFile._open() read image dimensions from the GD 2.x header and stored them in self._size without calling Image._decompression_bomb_check(), allowing a crafted .gd file to trigger excessive C-heap allocation when loaded. This issue is fixed in version 12.3.0.

Severity

7.5 (High)

Vulnerability from nvd – Published: 2026-07-06 18:52 – Updated: 2026-07-06 19:17

Title

Pillow BdfFontFile`: `Image.new()` called without `_decompression_bomb_check()` — bomb protection bypass via font loading

Summary

Pillow is a Python imaging library. Prior to 12.3.0, PIL/BdfFontFile.py bdf_char() read the BBX width and height field from a BDF font file and passed attacker-controlled dimensions to Image.new() without calling Image._decompression_bomb_check(), bypassing Pillow's documented decompression bomb protection and allowing excessive memory allocation. This issue is fixed in version 12.3.0.

CVE-2026-54060 (GCVE-0-2026-54060)

Vulnerability from nvd – Published: 2026-07-06 18:49 – Updated: 2026-07-07 14:08

Title

Pillow: `FontFile.compile()`: `Image.new()` called without `_decompression_bomb_check()`

Summary

Pillow is a Python imaging library. Prior to 12.3.0, PIL/FontFile.py FontFile.compile() assembled per-glyph images into a combined bitmap with Image.new("1", (xsize, ysize)) without calling Image._decompression_bomb_check(), allowing a font to trigger excessive allocation during conversion or saving. This issue is fixed in version 12.3.0.

Severity

7.5 (High)

Vulnerability from nvd – Published: 2026-07-06 18:46 – Updated: 2026-07-07 16:57

Title

Pillow: PcfFontFile._load_bitmaps()`: `Image.frombytes()` called without `_decompression_bomb_check()` — bomb protection bypass via PCF font loading

Summary

Pillow is a Python imaging library. Prior to 12.3.0, PIL/PcfFontFile.py _load_bitmaps() read glyph dimensions from the PCF METRICS section and passed them directly to Image.frombytes() without calling Image._decompression_bomb_check(), allowing crafted PCF font data to cause excessive memory allocation. This issue is fixed in version 12.3.0.

CVE-2026-4360 (GCVE-0-2026-4360)

Vulnerability from nvd – Published: 2026-06-30 14:45 – Updated: 2026-07-07 17:01

Title

Tarfile.extract() doesn't fully respect filter parameter

Summary

In the Tarfile.extract() function, the filter parameter is not passed properly when extracting hardlinks. An affected system that extracts content from untrusted tar files could end up writing files with an unexpected uid/gid despite the user passing filter='data' to the extract() function.

Severity

2 (Low)

CVE-2026-59198 (GCVE-0-2026-59198)

Vulnerability from cvelistv5 – Published: 2026-07-14 16:07 – Updated: 2026-07-14 19:55

Title

Pillow TGA RLE encoder can serialize up to ~57 KB of adjacent heap data into generated images

Summary

Pillow is a Python imaging library. From 5.2.0 until 12.3.0, Pillow's TGA RLE encoder reads past its packed row buffer when saving a mode 1 image with TGA RLE compression, allowing adjacent process heap bytes to be copied into the generated TGA file. This issue is fixed in version 12.3.0.

Severity

6.5 (Medium)

CVE-2026-59205 (GCVE-0-2026-59205)

Vulnerability from cvelistv5 – Published: 2026-07-14 15:48 – Updated: 2026-07-14 17:31

Title

Pillow: Controlled heap out-of-bounds write in `ImageCmsTransform.apply()` via output mode mismatch

Summary

Pillow is a Python imaging library. Prior to 12.3.0, Pillow's ImageCms.ImageCmsTransform.apply(im, imOut) API can trigger controlled native heap corruption when the caller supplies an output image whose mode does not match the transform's declared output mode. This issue is fixed in version 12.3.0.

Severity

7.5 (High)

CVE-2026-59203 (GCVE-0-2026-59203)

Vulnerability from cvelistv5 – Published: 2026-07-14 15:43 – Updated: 2026-07-14 15:49

Title

Pillow EpsImagePlugin negative %%BeginBinary byte count causes infinite loop denial of service

Summary

Pillow is a Python imaging library. From 12.0.0 through 12.2.0, Pillow's EPS parser in PIL/EpsImagePlugin.py accepts a negative byte count in the %%BeginBinary directive, allowing a crafted EPS file to cause Image.open() to seek backwards to the same directive and parse it repeatedly in an infinite loop. This issue is fixed in version 12.3.0.

Severity

5.3 (Medium)

Pillow: Heap out-of-bounds write `Image.paste()` / `Image.crop()` via signed coordinate overflow

Summary

Pillow is a Python imaging library. Prior to 12.3.0, Pillow public image coordinate APIs can trigger a native heap out-of-bounds write when given coordinates near the signed 32-bit integer limits in Image.paste(), Image.crop(), or Image.alpha_composite(). This issue is fixed in version 12.3.0.

CVE-2026-59204 (GCVE-0-2026-59204)

Vulnerability from cvelistv5 – Published: 2026-07-14 15:38 – Updated: 2026-07-14 15:38

Title

Pillow JPEG2000 tiled decode retains a growing scratch buffer and can be used for denial of service

Summary

Pillow is a Python imaging library. From 8.2.0 through 12.2.0, src/libImaging/Jpeg2KDecode.c accumulates total_component_width across every tile in a JPEG2000 image instead of recomputing it per tile, allowing a crafted tiled JPEG2000 file to force substantially higher transient memory usage and trigger out-of-memory failures during decoding. This issue is fixed in version 12.3.0.

CVE-2026-59890 (GCVE-0-2026-59890)

Vulnerability from cvelistv5 – Published: 2026-07-08 16:02 – Updated: 2026-07-08 16:44

Title

setuptools: MANIFEST.in exclusion bypass in sdist via Unicode normalization collision (NFC/NFD) on macOS APFS/HFS+

Summary

setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python packages. Prior to 83.0.0, FileList applied MANIFEST.in exclude, global-exclude, recursive-exclude, and prune directives by matching compiled glob patterns against on-disk file names without Unicode normalization, so on macOS APFS or HFS+ an NFD file name could bypass an NFC exclusion rule and be packed into a source distribution. This issue is fixed in version 83.0.0.

Severity

6.1 (Medium)

CVE-2026-55379 (GCVE-0-2026-55379)

Vulnerability from cvelistv5 – Published: 2026-07-06 18:52 – Updated: 2026-07-06 19:17

Title

Pillow BdfFontFile`: `Image.new()` called without `_decompression_bomb_check()` — bomb protection bypass via font loading

Summary

Pillow is a Python imaging library. Prior to 12.3.0, PIL/BdfFontFile.py bdf_char() read the BBX width and height field from a BDF font file and passed attacker-controlled dimensions to Image.new() without calling Image._decompression_bomb_check(), bypassing Pillow's documented decompression bomb protection and allowing excessive memory allocation. This issue is fixed in version 12.3.0.

Severity

7.5 (High)

Vulnerability from cvelistv5 – Published: 2026-07-06 18:50 – Updated: 2026-07-06 19:23

Title

Pillow GdImageFile decompression bomb protection bypass

Summary

Pillow is a Python imaging library. Prior to 12.3.0, PIL/GdImageFile.py GdImageFile._open() read image dimensions from the GD 2.x header and stored them in self._size without calling Image._decompression_bomb_check(), allowing a crafted .gd file to trigger excessive C-heap allocation when loaded. This issue is fixed in version 12.3.0.

CVE-2026-54060 (GCVE-0-2026-54060)

Vulnerability from cvelistv5 – Published: 2026-07-06 18:49 – Updated: 2026-07-07 14:08

Title

Pillow: `FontFile.compile()`: `Image.new()` called without `_decompression_bomb_check()`

Summary

Pillow is a Python imaging library. Prior to 12.3.0, PIL/FontFile.py FontFile.compile() assembled per-glyph images into a combined bitmap with Image.new("1", (xsize, ysize)) without calling Image._decompression_bomb_check(), allowing a font to trigger excessive allocation during conversion or saving. This issue is fixed in version 12.3.0.

Severity

7.5 (High)

Pillow: PcfFontFile._load_bitmaps()`: `Image.frombytes()` called without `_decompression_bomb_check()` — bomb protection bypass via PCF font loading

Summary

Pillow is a Python imaging library. Prior to 12.3.0, PIL/PcfFontFile.py _load_bitmaps() read glyph dimensions from the PCF METRICS section and passed them directly to Image.frombytes() without calling Image._decompression_bomb_check(), allowing crafted PCF font data to cause excessive memory allocation. This issue is fixed in version 12.3.0.

CVE-2026-55798 (GCVE-0-2026-55798)

Vulnerability from cvelistv5 – Published: 2026-07-06 18:44 – Updated: 2026-07-07 15:19

Title

Pillow: WindowsViewer.get_command() OS command injection via unescaped shell path

Summary

Pillow is a Python imaging library. Prior to 12.3.0, WindowsViewer.get_command() constructed a cmd.exe shell command by directly embedding a file path into an f-string without escaping and passed the result to subprocess.Popen(..., shell=True), allowing shell metacharacters in the file path to inject arbitrary cmd.exe commands. This issue is fixed in version 12.3.0.

Severity

4.5 (Medium)

CVE-2026-4360 (GCVE-0-2026-4360)

Vulnerability from cvelistv5 – Published: 2026-06-30 14:45 – Updated: 2026-07-07 17:01

Title

Tarfile.extract() doesn't fully respect filter parameter

Summary

In the Tarfile.extract() function, the filter parameter is not passed properly when extracting hardlinks. An affected system that extracts content from untrusted tar files could end up writing files with an unexpected uid/gid despite the user passing filter='data' to the extract() function.

Severity

2 (Low)
