Python Pypdf Redhat Suse

Description

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.

Analysis

Resource exhaustion in pypdf versions prior to 6.7.1 occurs when processing maliciously crafted PDF files with manipulated /ToUnicode font entries, causing excessive memory consumption and processing delays during text extraction operations. A local attacker with file access can exploit this to degrade system performance, though no code execution or data compromise is possible. …
