Summary

Panic on negative member size in Reader.Read in github.com/blakesmith/ar

Details

Reader.Next parses the 10-byte decimal size field of an archive member header with strconv.ParseInt without rejecting negative values. A header with a negative size leaves the reader with a negative remaining byte count, causing the subsequent call to Reader.Read to panic with a slice bounds out of range error when slicing the caller's buffer.
