Title:
Xenial/16.04: GIMP needs a security update - unfixed issues (CVE-2017:
17784-17789).
Status in gimp package in Ubuntu:
Confirmed
Bug description:
Hello.
GIMP package ('Universe/Security' section), available in
"Xenial"/16.04 LTS Release, contains unfixed security issues and is
vulnerable to, for example, heap-buffer over-read, out of bounds read
and stack-based buffer over-read etc. The whole thing is pretty
strange, because Ubuntu Releases released before and after "Xenial",
contains updated GIMP package!
Anyway, it looks this way: in "Trusty" the available version is:
'2.8.10-0ubuntu1.2' (please see [1]). "Bionic" has '2.8.20-1.1'
version (please see [2]). Both Releases contains fixes for mentioned
security issues: CVE-2017-* etc. However, GIMP version in "Xenial" is
'2.8.16-1ubuntu1.1' and does not contain any security updates from
2017. (The last one is from Thu, 30 Jun 2016.; please see [3]).
Security updates with fixes for mentioned CVE's (please compare
changes in 1. and 2. with 3.) were released on Thu., 18 Jan 2018 - for
"Trusty" and Tue., 26 Dec 2017 - for "Bionic". In "Xenial", the last
security update is from Thu., 30 Jun 2016 (fix for CVE-2016-4994) and
there is no further updates!
Here is a CVE list of security issues not fixed in "Xenial", but in
"Trusty" and "Bionic" etc.:
1/ CVE-2017-17784: Heap-buffer over-read in load_image file-gbr.c
2/ CVE-2017-17785: Heap-based buffer overflow in fli_read_brun function
3/ CVE-2017-17786: Out of bounds read
4/ CVE-2017-17787: Heap-based buffer over-read in read_creator_block
5/ CVE-2017-17788: Stack-based buffer over-read in xcf_load_stream
6/ CVE-2017-17789: Heap-based buffer overflow in read_channel_data
And the most important thing: if User had installed GIMP package in
"Xenial" Release, he is affected - since one year, at least - because
of a vulnerable version. Security issues, mentioned above, are from
2017. So, maybe it's a good opportunity to update GIMP to v2.10.2
version, released on 20., May 2018? (Version 2.8.X is very outdated).
I wanted to send an email to Mr Marc Deslauriers, because he made the
last security update for GIMP in "Xenial" (fix for CVE-2016-4994). But
I decided to report a bug on Launchpad. I hope that it's an acceptable
way. If not, I'm sorry.
By the way: similar problems with unfixed security issues, can be
found e.g. in Audacious and Parole packages. But that's a different
story, completely different story...
Thanks, best regards.
