Описание
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.
A flaw was found in pypdf. Processing maliciously crafted PDF files utilizing a sequence of FlateDecode filters can exhaust available RAM. An attacker can trigger this condition by simply reading the malicious PDF file. This results in a resource exhaustion condition, leading to an application level denial of service. This vulnerability stems from insufficient resource constraints during the decompression process.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
