Описание
pypdf is a free and open-source pure-python PDF library. Prior to 6.7.1, an attacker who uses this vulnerability can craft a PDF which leads to long runtimes and large memory consumption. This requires parsing the /ToUnicode entry of a font with unusually large values, for example during text extraction. This vulnerability is fixed in 6.7.1.
A flaw was found in pypdf. An attacker can craft a malicious PDF file containing unusually large values in the /ToUnicode entry of a font. When this crafted PDF is processed, for example during text extraction, it can lead to excessive resource consumption, resulting in a Denial of Service (DoS) due to long runtimes and large memory usage.
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.
