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`."},{"lang":"es","value":"pypdf es una librería de PDF pura de Python gratuita y de código abierto. Un atacante que utilice una vulnerabilidad presente en las versiones 3.7.0 a 3.16.4 puede crear un PDF que genere un bucle infinito.
