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...

GHSA-55H5-XMCQ-C37V pypdf: Possible long runtimes for repeated malformed cross-reference entries

Impact An 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. Patches This has been fixed in pypdf==6.14.0. Workarounds If you cannot upgrade yet, consider applying the changes fr...

pypdf: Possible large memory usage for wrong image dimensions

Impact An 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. Patches This has been fixed in pypdf==6.14.0. Workarounds If you cannot upgrade yet, consid...

PYSEC-2026-3009 pypdf: Possible infinite loop when retrieving fonts for layout-mode text extraction
