NVD Description

Note: Versions mentioned in the description apply only to the upstream nemo package and not the nemo package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

pypdf is a free and open-source pure-python PDF library. Prior to version 6.0.0, an attacker can craft a PDF which leads to the RAM being exhausted. This requires just reading the file if a series of FlateDecode filters is used on a malicious cross-reference stream. Other content streams are affected on explicit access. This issue has been fixed in 6.0.0. If an update is not possible, a workaround involves including the fixed code from pypdf.filters.decompress into the existing filters file.
