Title:
Segmentation fault from Resaveimage() in verdandi
Status in Hugin:
Invalid
Bug description:
Hello,
Using hugin (2020.0.0) software verdandi adopting vigra, I encountered on the
segmentation fault error.
The root cause is assumed to be from
Illegal reference by void vigra::StandardValueAccessor<unsigned
short>::set<unsigned short, unsigned short*>(unsigned short, unsigned short*&).
of debian package
libvigraimpex-dev/focal,now 1.11.1+dfsg-7ubuntu1
The set() is assumed to be out-of-bound without any appropriate check of the
valid address dereferenced by scanline.
(src: /include/vigra/impex.hxx:82-89)
Vigra functions to the root cause are called starting from ResaveImage() in
verdandi.cpp:213.
I attach a proof-of-concept file for the sake of developers' testing.
Below is the running command and backtrace;
oren@ubuntu:~$ sudo ./hugin-2020.0.0/build/src/tools/verdandi --output=1.tif
./poc
