Multiple vulnerabilities in Focal and Jammy

Patched packages for Focal and Jammy are building in my PPA: https://launchpad.net/~luis220413/+archive/ubuntu/security-updates.

The attachment "gimp_focal.debdiff" seems to be a debdiff. The ubuntu-sponsors team has been subscribed to the bug report so that they can review and hopefully sponsor the debdiff. If the attachment isn't a patch, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are member of the ~ubuntu-sponsors, unsubscribe the team.

Thanks Luís, we'll have a look at this. What testing have you done with the resulting packages?

Thanks

I have not done any testing.

Hi Luis,

as part of the sponsoring/updating process, you have to run tests and inform us about its results and instructions.

Testing an update is important. At a minimum, be sure to:
1. build in a clean build environment
2. verify the package still installs
3. verify the package upgrades cleanly
4. verify the package still functions properly
5. use public exploits and Proof of Concept(s) (PoC) (if available) to verify the bug is fixed
6. run any test suites available for such package

This bug was fixed in the package gimp - 2.10.32-1

I took a look at the debdiffs in #2, #3, and #8, and here are my comments:

For Bionic:

- The package doesn't build with the debdiff provided. Please fix and make sure it builds before submitting it again.
- In CVE-2022-32990-2.patch, you dropped the section that patches xcf_load_buffer, but in Bionic, the function is called xcf_load_hierarchy, please add the section back and patch the appropriate function.

For Focal:
- The patch for CVE-2018-12713 is missing, please add it.

For Jammy:

- The patch for CVE-2018-12713 is missing, please add it.
- You seemed to have bumped the version of gegl required in the debian/control file for no reason, and it is not mentioned in the changelog. Please remove this change.

Once those changes are done and new debdiffs have been attached, please detail the testing that you performed to make sure Gimp still works, thanks!

If there is substantial demand for these CVEs getting fixed, please comment on this bug or otherwise notify me (for example via email).

> All the CVEs fixed by the attached debdiffs have priority low or negligible.

I don't think it is right to try and say these should not be sponsored until a higher priority issue is found - it is just that other higher priority updates for other packages will usually take precedence. Please try not to talk with authority about things which you do not have authority over.

Sorry for the comment. I have hidden it and I will update my patches and request sponsorship.

There are no updated debdiffs to sponsor, unsubscribing ubuntu-security-sponsors for now. Please resubscribe the group once updated debdiffs have been attached to this bug. Thanks!
