** Description changed:
- Using version 2.31.91 backported on lucid i recieve a segmentation fault
- on rotating the first page of a text scan at 300 DPI. System is AMD64
- with all updates. Scanner is HP Officejet 5515 AIO.
+ Impact: simple-scan crashes when completing a single page being scanned or
rotated
+ Resolution: Change in upstream project to fix rendering loop accessing pixels
outside of image (patch in package branch and in comments below)
+ To reproduce:
+ 1. Run simple-scan, e.g.
+ $ simple-scan test
+ 2. Scan one page
+ Expected result: Page is scanned and shows correct data
+ Observed result: simple-scan crashes when page complete or if page is rotated
while scanning (note that since this bug is due to memory corruption it is not
guaranteed to crash. A reliable method is to run simple-scan through valgrind
as this will show invalid reads when rendering the page).
- Way to reproduce: open simple-scan, click scan, wait for finishing,
- click rotate -> crash.
-
- What's curious is that on rotating left it sometimes doesn't crash, but
- right means always killing the app.
+ Patch has been tested and crash does not occur anymore, no errors
+ reported by valgrind. Bug is well-defined (off by one error), no
+ regression problems expected.
