Description alex 2022-06-05 23:11:53 UTC
Description of problem:
GPG crashes when using the force-aead and personal-aead-preferences options.

Version-Release number of selected component (if applicable):
2.3.6-1.fc36

How reproducible:
Always

Steps to Reproduce:
1. gpg --quick-gen-key testkey
2. Add "force-aead" and "personal-aead-preferences OCB" to gpg.conf. Using command-line arguments to set these won't work.
3. gpg -aer testkey
4. gpg -ac
5. gpg -asc

Actual results:
Output of "gpg -aer testkey" and "gpg -asc":
gpg: unsupported AEAD algo -6
gpg: unsupported AEAD algo -6
gpg: Ohhhh jeeee: Assertion "a->filter == block_filter" in iobuf_set_partial_body_length_mode failed (iobuf.c:2764)
Aborted (core dumped)

Output of "gpg -ac":
gpg: unsupported AEAD algo 10
gpg: symmetric encryption of '[stdin]' failed: Invalid cipher mode

Expected results:
GPG does not crash.

Comment 1 Jakub Jelen 2022-06-07 09:59:53 UTC
Thank you for the report. Running the gpg under valgrind shows some uninitialized variables, which will probably cause this issue. I filled the issue upstream with a patch that solves the issue for me:

https://dev.gnupg.org/T6019

When I will hear from upstream, I will update Fedora package to fix this problem.

This was fixed in 2.3.7 -- closing as a current release.
