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`. Users unable to upgrade should validate and PDFs prior to iterating over their content stream.

The remote openSUSE 15 host has a package installed that is affected by a vulnerability as referenced in the openSUSE- SU-2024:0366-1 advisory.

    - CVE-2022-24859: Fixed infinite loop vulnerability (boo#1198588)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-6176-1 advisory.

    It was discovered that PyPDF2 incorrectly handled certain PDF files. If a

    user or automated system were tricked into processing a specially crafted file, an attacker could possibly     use this issue to consume system resources, resulting in a denial of service.
