Affected: Homebrew: pdfalyzer

### Impact

An attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires opening an incomplete file without a `trailer`.

### Patches

This has been fixed in [pypdf==6.21.4](https://github.com/py-pdf/pypdf/releases/tag/6.21.4).

### Workarounds

If you cannot upgrade yet, consider applying the changes from PR [#4289](https://github.com/py-pdf/pypdf/pull/4289).

pypdf is a free and open-source pure-python PDF library. Prior to 6.21.4, pypdf can enter an infinite loop while opening a crafted incomplete PDF whose standard cross-reference table reaches the end of the file without a trailer. The trailer search can repeatedly rewind to the same stream position instead of terminating when parsing makes no progress, blocking the processing thread. This issue is fixed in version 6.21.4.
