outguess-0.2 claims to support PPM image format for embedding/extracting stegonographic data. While testing outguess with PPM (ascii and raw) files I received the following errors. outguess -k "testtest" -d info main2_lg.ppm test.ppm Reading main2_lg.ppm....

Have you tried a newer version? I see that 0.6 was released a long time ago. Upstream seems unmaintained.
Correct me if I'm wrong, but stegdetect-0.6 and outguess-0.2 are two separate code-bases.
Hello treecleaner, This version (and last) is from 2001-10. Upstream is not responsive. It has segmentation fault, but it seems that noone in the crypto herd is about to solve this for upstream. It has no dependencies in the tree. I suggest to remove this one from the tree. If someone wishes to solve this issue, please reassign to your-self. Thanks!
nothing depends on it -> package.mask'ed, pending removal
Guess Alec really needs to follow his own guidelines ...
