GHSA-2fcv-qww3-9v6h: Babylon's malformed vote extensions are not rejected

### Summary Adversarial validators can send large vote extensions by using non-existing protobuf tags. This will result in the rejection of the subsequent block proposal. Eventually, all block proposals will be rejected by all validators. ### Impact A small group of adversarial validators can cause a chain halt.

GHSA-m449-cwjh-6pw7: pypdf's LZWDecode streams be manipulated to exhaust RAM

### Impact An attacker who uses this vulnerability can craft a PDF which leads to a memory usage of up to 1 GB per stream. This requires parsing the content stream of a page using the LZWDecode filter. This is a follow up to [GHSA-jfx9-29x2-rv3j](https://github.com/py-pdf/pypdf/security/advisories/GHSA-jfx9-29x2-rv3j) to align the default limit with the one for *zlib*. ### Patches This has been fixed in [pypdf==6.4.0](https://github.com/py-pdf/pypdf/releases/tag/6.4.0). ### Workarounds If users cannot upgrade yet, use the line below to overwrite the default in their code: ```python pypdf.filters.LZW_MAX_OUTPUT_LENGTH = 75_000_000 ```
