Subject: [PATCH] warc: consume data once read
|
|
|
|
The warc decoder only used read ahead, it wouldn't actually consume
|
|
data that had previously been printed. This means that if you specify
|
|
an invalid content length, it will just reprint the same data over
|
|
and over and over again until it hits the desired length.
|
|
|
|
This means that a WARC resource with e.g.
|
|
Content-Length: 666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666666665
|
|
but only a few hundred bytes of data, causes a quasi-infinite loop.
|
|
|
|
Consume data in subsequent calls to _warc_read.
|
|
|
|
Found with an AFL + afl-rb + qsym setup.
