pypdf: Possible long runtimes/large memory usage for large CID font width ranges

ImpactAn attacker who uses this vulnerability can craft a PDF which leads to long runtimes and large memory consumption. This requires parsing the font width entries of a font with unusually large values, for example during text extraction. PatchesThis has been fixed in pypdf==6.15.0. Workarounds...

python-pillow: Pillow: Denial of Service via crafted BDF font file

A flaw was found in Pillow, a Python imaging library. This vulnerability allows a remote attacker to cause a Denial of Service DoS by providing a specially crafted BDF font file. The library's image processing function fails to properly validate dimensions from the font file, bypassing a critical...
