[Bug 61300] New: Very slow processing on corrupted file
https://bz.apache.org/bugzilla/show_bug.cgi?id=61300
Bug ID: 61300
Summary: Very slow processing on corrupted file
Product: POI
Version: 3.17-dev
Hardware: PC
Status: NEW
Severity: minor
Priority: P2
Component: POIFS
Assignee: dev@poi.apache.org
Reporter: tallison@mitre.org
Target Milestone: ---
Created attachment 35141

triggering file
I need to figure out if this is a POIFs bug or a parseSummaries bug. This is
triggered by a corrupted file.
At this location:
at org.apache.poi.util.IOUtils.copy(IOUtils.java:296)
at org.apache.poi.util.IOUtils.peekFirstNBytes(IOUtils.java:64)
at
org.apache.poi.hpsf.PropertySet.isPropertySetStream(PropertySet.java:393)
at org.apache.poi.hpsf.PropertySet.<init>(PropertySet.java:191)
at
org.apache.tika.parser.microsoft.SummaryExtractor.parseSummaryEntryIfExists(SummaryExtractor.java:83)
at
org.apache.tika.parser.microsoft.SummaryExtractor.parseSummaries(SummaryExtractor.java:73)
while((count = inp.read(buff)) != -1) {
if(count > 0) {
out.write(buff, 0, count);
}
}
On the first iteration, the pos in inp is 0, but then the pos goes negative on
each iteration, and this loop iterates for a very long time.
The source file that I corrupted is: testEXCEL_embeddedPDF_windows.xls

How can we reproduce this with POI alone? How is the document opened in Tika?

Dominik,
I'm sorry for never responding. Y, looks like I could reproduce this in pure
POI.
