https://bugzilla.suse.com/show_bug.cgi?id=1216774 Bug ID: 1216774 Summary: VUL-0: CVE-2023-46250: pypdf: infinite loop condition may be triggered to cause denial of service Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.6 Hardware: Other URL: https://smash.suse.de/issue/383718/ OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Python Assignee: simonf.lees@suse.com Reporter: smash_bz@suse.de QA Contact: security-team@suse.de CC: stoyan.manolov@suse.com Target Milestone: --- Found By: Security Response Team Blocker: --- pypdf is a free and open-source pure-python PDF library. An attacker who uses a vulnerability present in versions 3.7.0 through 3.16.4 can craft a PDF which leads to an infinite loop. This infinite loop blocks the current process and can utilize a single core of the CPU by 100%. It does not affect memory usage. That is, for example, the case when the pypdf-user manipulates an incoming malicious PDF e.g. by merging it with another PDF or by adding annotations. The issue was fixed in version 3.17.0. As a workaround, apply the patch manually by modifying `pypdf/generic/_data_structures.py`.
