HIGHpypdf < 6.1.3 - Denial of Service via DCTDecode Inline Image Parsing
Title source: llmDescription
pypdf is a free and open-source pure-python PDF library. Prior to version 6.1.3, 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 which has an inline image using the DCTDecode filter. This has been fixed in pypdf version 6.1.3.
