Denial Of Service (DoS)

pypdf is vulnerable to Denial of Service DoS. The vulnerability is due to improper handling of unterminated inline images using the ASCII85 or ASCIIHex filters during PDF parsing, which allows an attacker to craft a malicious PDF that triggers an infinite loop and causes a denial of service...

pypdf: Possible infinite loop for not terminated inline images (ASCII85 and ASCIIHex filter)

Impact An attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires parsing the content stream of a page with a not terminated inline image, as done when extracting the page text for example. It only affects the ASCII85 and ASCIIHex filters. Patches This...
