CVE-2026-54059 Pillow: PcfFontFile._load_bitmaps()`: `Image.frombytes()` called without `_decompression_bomb_check()` — bomb protection bypass via PCF font loading

Pillow is a Python imaging library. Prior to 12.3.0, PIL/PcfFontFile.py loadbitmaps read glyph dimensions from the PCF METRICS section and passed them directly to Image.frombytes without calling Image.decompressionbombcheck, allowing crafted PCF font data to cause excessive memory allocation. Thi...

Pillow: Pillow: Denial of Service via decompression bomb in FITS image processing

A flaw was found in Pillow, a Python imaging library. This vulnerability allows a remote attacker to trigger a denial of service DoS by providing a specially crafted FITS image file. The library's failure to limit the amount of GZIP-compressed data during decoding can lead to unbounded memory...

GHSA-XV9W-7V6Q-HPJH fluent-plugin-s3 Vulnerable to Denial of Service (DoS) via Decompression Bomb in `in_s3`

The fluent-plugin-s3 plugin specifically the ins3 input plugin supports reading and decompressing heavily compressed files such as gzip, lzma2, and lzop from Amazon S3. It was discovered that the plugin read the entire decompressed payload into memory at once without enforcing a strict size limit...

GHSA-J9CW-HWQF-85W7 Fluentd is Vulnerable to Denial of Service (DoS) via Gzip Decompression Bomb in `in_http` and `in_forward`

Fluentd's inhttp and inforward plugins support receiving gzip-compressed data. While Fluentd correctly enforces size limits on the incoming compressed payloads e.g., via bodysizelimit or chunksizelimit, it was discovered that there is no limit enforced on the size of the decompressed data. If a...
