Subject: exiftran: dies with Segmentation fault when rotating an image
Package: exiftran
Version: 2.07-8
Justification: renders package unusable
Severity: grave
exiftran dies when it tries to rotate a JPEG file:
$ ./exiftran -a -i -p ../20110711163247.jpg
processing ../20110711163247.jpg
Segmentation fault
It doesn't seem to depend on the picture (it seems to happen with all
portrait pictures I just got off my camera).
Attached is a backtrace with a version of exiftran built while keeping
the symbols.
I did notice this during the build:
/usr/bin/ld: warning: libjpeg.so.62, needed by /usr/lib/libtiff.so, may
conflict with libjpeg.so.8
but don't known whether it is relevant as the stacktrace doesn't include
libjpeg code directly. I haven't been able to get another combination of
libjpeg*-dev and libtiff*-dev installed together to test whether it may
be relevant.
From a quick look at the code it seems that exiftran uses libjpeg
internals and perhaps the meaning of comp_info has changed between
libjpeg62 and libjpeg8?
