pypdf: Possible infinite loop for not terminated inline images

ImpactAn 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. PatchesThis has been fixed in pypdf==6.14.1. WorkaroundsIf you...

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

ImpactAn 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. PatchesThis ha...

pypdf: Possible long runtimes for repeated malformed cross-reference entries

ImpactAn attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires cross-reference streams with repeated malformed cross-reference streams. PatchesThis has been fixed in pypdf==6.14.0. WorkaroundsIf you cannot upgrade yet, consider applying the changes from ...

pypdf: Possible large memory usage for wrong image dimensions

ImpactAn attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires loading images where the declared size values are much too large compared to the actual data. PatchesThis has been fixed in pypdf==6.14.0. WorkaroundsIf you cannot upgrade yet, consider...

Denial Of Service (DoS)

pypdf is vulnerable to Denial Of Service DoS. The vulnerability is due to inefficient recovery of malformed cross-reference streams in crafted PDF files, which allows an attacker to cause excessive processing time and trigger a denial-of-service condition...

Denial Of Service (DoS)

pypdf is vulnerable to Denial Of Service DoS. The vulnerability is due to improper validation of declared image size values during PDF image parsing, which allows an attacker to craft a malicious PDF that triggers excessive memory consumption and causes a denial-of-service condition...
