Package: xcftools
Version: 1.0.4-1
Severity: important
I really like the xcftools package, because it lets me author things
in Gimp and then automate operations on them (e.g. let a Makefile
generate jpeg images from a sandwhich of layers). However, this bug is
a problem for me currently:
I try to extract individual layers, clipped to the canvas size. It
seems that at least sometimes, for at least some layers which extends
past the edges of the canvas, xcf2pnm fails. On this amd64 system, it
passes an unreasonable size to malloc(). On my PPC Debian 4.0 system
and xcftools (1.0.4-1) it dies with SIGILL instead. Possibly, almost
anything can happen.
xcf2png fails in the same way.
Some might suspect that this as a security issue. I have chosen not to
file it as such, but feel free to raise the severity if you think it's
important.
I have attached two minimal example files (gzipped). The -bigcanvas
variant was created in Gimp with "Fit canvas to layers". And here is a
terminal session which shows the problem:

I'd really appreciate a fix. I could try debugging it myself, but I have a
feeling someone else (e.g. the upstream author) who knows XXF better can
succeed in an hour or so.

Jörgen

Description:
xcftools - command-line tools for extracting data for XCF files
Closes: 525920 533361
Changes:
xcftools (1.0.7-1) unstable; urgency=high
.
* Adopted (Closes: #525920)
+ with urgency=high for the security issue
+ with new debian/copyright according to upstream's relicensing
* New upstream release (1.0.7)
+ Fix GPL-to-PD transition: missed copyright blurb in online banner.
* IMPORTANT CHANGE: xcfview is rewritten to use xdg-utils in order to find
an image viewer instead of parsing /etc/mailcap on its own
.
* New upstream release (1.0.6)
+ Change licensing from GPL-2 to PD.
+ Fix bug: A layer without an alpha channel bug with an active layer mask
was wrongly considered to obscure all lower layers.
+ Fix bug: xcf2pnm would guess PBM as the output format even if the
background was explicitly set to an intermediate gray, or if -T might
produce grays.
.
* New upstream release (1.0.5)
+ Fix various bugs if extracted part of image contains pixels with
negative canvas-based coordinates. Thanks Jörgen Grahn (Closes: #533361,
CVE-2009-2175)
+ Minor manpage fixes; -C description should be less confusing now.
+ $(DESTDIR) honored in Makefile's install target
* Use quilt for patches
* Bump standards-version: 3.8.2
* Added debian/watch
* Switched to debhelper 7
* debian/control: Reorganized Recommends and Suggests
