CVE-2026-45304

CVE-2026-45304 affects Symfony’s YAML Parser (Symfony\Component\Yaml\Parser). Before versions 5.4.52, 6.4.40, 7.4.12, and 8.0.12, the parser resolved YAML collection aliases recursively, enabling a small untrusted YAML input to expand into a multi-gigabyte structure and exhaust memory. Impact is ...

CVE-2026-45133

CVE-2026-45133 affects Symfony YAML parsing: when fed attacker-controlled input, deeply nested mappings/sequences can cause unbounded recursion in both Parser::parseBlock() and Inline::parseSequence()/Inline::parseMapping(), exhausting PHP stack and crashing workers. Affected versions include Sym...

UBUNTU-CVE-2026-59200

Pillow is a Python imaging library. From 5.1.0 until 12.3.0, PdfParser.PdfStream.decode in PIL/PdfParser.py calls zlib.decompress with bufsize set to the PDF stream Length field without bounding the decompressed output size, allowing a crafted FlateDecode PDF stream to exhaust memory from a small...
