New submission from Eric Huss: Creating a ZipFile object with a certain type of zip file can cause it to go into an infinite loop. The problem is the new extra field parsing routine. It unpacks integers as a signed value, which if they are sufficiently large (over 32767), then it will loop forever.
There are many places in the zipfile module that incorrectly unpack values as signed integers, but this is the only place that I can determine that causes a serious problem. Attached is a fix. ---------- components: Library (Lib) files: zipfile.patch messages: 58606 nosy: ehuss severity: normal status: open title: zipfile hangs on certain zip files type: behavior versions: Python 2.5, Python 2.6 Added file: http://bugs.python.org/file8948/zipfile.patch __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1622> __________________________________
