1803038 – dnf crashes with an UTF-8 char in a repository filename

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
DNF crashes with an UTF-8 char in the repository filename

Version-Release number of selected component (if applicable):
libdnf-0.35.1-9.el8_1.x86_64
dnf-4.2.7-7.el8_1.noarch

How reproducible:
100%

Steps to Reproduce:
1. touch '/etc/yum.repos.d/team'$'\303''_epel.repo' 
2. dnf repolist

Actual results:
# dnf repolist
Updating Subscription Management repositories.
Unable to read consumer identity
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Segmentation fault (core dumped)

Expected results:
No crash.

Additional info:
This looks similar to another bug, but this commit has already been backported:
https://github.com/rpm-software-management/libdnf/commit/97c23dfff803ef30b4d25a224218da1442a49220

I will attach the corresponding coredump.

Comment 1 marek77 2020-02-14 13:25:19 UTC

The segfault still happens on Fedora 30, but is fixed on Fedora 31:

$ cat /etc/redhat-release 
Fedora release 30 (Thirty)

$ sudo touch '/etc/yum.repos.d/team'$'\303''_epel.repo'

$ sudo dnf repolist
Segmentation fault (core dumped)

$ rpm -q dnf libdnf
dnf-4.2.11-2.fc30.noarch
libdnf-0.35.5-5.fc30.x86_64

=======================================================================

$ cat /etc/redhat-release
Fedora release 31 (Thirty One)

$ sudo touch '/etc/yum.repos.d/team'$'\303''_epel.repo'

$ sudo dnf repolist
Warning: failed loading '/etc/yum.repos.d/team\udcc3_epel.repo', skipping.

<WORKS OK :) >

$ rpm -q dnf libdnf
dnf-4.2.18-1.fc31.noarch
libdnf-0.43.1-2.fc31.x86_64

Comment 2 Pavla Kratochvilova 2020-02-19 09:55:54 UTC

The segfault is not dependent on the version of libdnf/dnf, but rather on the version of swig that is used for libdnf build. When I build the latest version of libdnf on Fedora 30 (with swig-3.0.12-26.fc30.x86_64), dnf segfaults, whereas when I build the latest version of libdnf on Fedora 31 (with swig-4.0.1-3.fc31), dnf doesn't segfault.

I will clone this bug for swig with more details.
