CVSS: 6.2EPSS: 0%CPEs: 2EXPL: 1CVE-2023-36464 – Infinite Loop when a comment isn't followed by a character in pypdf
https://notcve.org/view.php?id=CVE-2023-36464
pypdf is an open source, pure-python PDF library. In affected versions an attacker may craft a PDF which leads to an infinite loop if `__parse_content_stream` is executed. That is, for example, the case if the user extracted text from such a PDF. This issue was introduced in pull request #969 and resolved in pull request #1828. Users are advised to upgrade. • https://github.com/py-pdf/pypdf/pull/1828 https://github.com/py-pdf/pypdf/pull/969 https://github.com/py-pdf/pypdf/security/advisories/GHSA-4vvm-4w3v-6mr8 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVSS: 6.2EPSS: 0%CPEs: 2EXPL: 2CVE-2022-24859 – Manipulated inline images can cause Infinite Loop in PyPDF2
https://notcve.org/view.php?id=CVE-2022-24859
PyPDF2 is an open source python PDF library capable of splitting, merging, cropping, and transforming the pages of PDF files. In versions prior to 1.27.5 an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop if the PyPDF2 if the code attempts to get the content stream. The reason is that the last while-loop in `ContentStream._readInlineImage` only terminates when it finds the `EI` token, but never actually checks if the stream has already ended. This issue has been resolved in version `1.27.5`. • https://github.com/py-pdf/PyPDF2/issues/329 https://github.com/py-pdf/PyPDF2/pull/740 https://github.com/py-pdf/PyPDF2/releases/tag/1.27.5 https://github.com/py-pdf/PyPDF2/security/advisories/GHSA-xcjx-m2pj-8g79 https://lists.debian.org/debian-lts-announce/2022/06/msg00001.html https://lists.debian.org/debian-lts-announce/2023/06/msg00013.html • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
