Description SMASH SMASH 2023-11-01 05:34:57 UTC 
pypdf is a pure-python PDF library capable of splitting, merging, cropping, and
transforming the pages of PDF files. An attacker who uses this vulnerability can
craft a PDF which leads to unexpected long runtime. This quadratic runtime
blocks the current process and can utilize a single core of the CPU by 100%. It
does not affect memory usage. This issue has been addressed in PR 808 and
versions from 1.27.9 include this fix. Users are advised to upgrade. There are
no known workarounds for this vulnerability.
