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.

Fixed In Version: rpmlint-0.94-3.1.el6
Doc Type: Bug Fix
Doc Text:
When a package had a UTF-8 encoding error in the description, or the description was encoded in a different character set, then rpmlint terminated unexpectedly with a segmentation fault. With this update, rmplint returns an error message that the description has incorrectly encoded UTF-8 data (tag-not-utf8 error), and crashes no longer occur in the described scenario.

Description Alicja Kario 2013-04-30 08:29:06 UTC 
Description of problem:
When a package has a UTF-8 encoding error in description (or description encoded in some other charset) rpmlint crashes.

Version-Release number of selected component (if applicable):
rpmlint-0.94-2.el6.noarch

How reproducible:
Always

Steps to Reproduce:
1. Create a spec file having characters from other charset in description (e.g. using "echo Łódź | iconv -f utf8 -t cp1250 >> package.spec")
2. Build a package using rpmbuild -ba
3. run "rpmlint -i package.rpm"
  
Actual results:
rpmlint-test-tag-not-utf8.noarch: W: spelling-error %description -l en_US utf -> fut, Ute, Utah
The value of this tag appears to be misspelled. Please double-check.

0 packages and 0 specfiles checked; 0 errors, 2 warnings.

UnicodeEncodeError: 'ascii' codec can't encode character u'\xf3' in position 74: ordinal not in range(128)

Expected results:
Error message that the description has wrongly encoded utf-8 data (tag-not-utf8 error)

Additional info:
Comment 5 Alicja Kario 2013-05-27 13:26:24 UTC 
the 'rpmlint' command must be run in non unicode enabled environment:

export LC_ALL=POSIX
export LANG=POSIX
TTY="`/usr/bin/tty`"

# stop unicode
kbd_mode -a
if test -t ; then
        printf '\033%%@'
fi
stty -iutf8

uid="`id -u 2>/dev/null`" ||:
if [ "$uid" = '0' ]; then
        [ ! -r "$HOME/.kbd/.keymap_sv" ] ||
                loadkeys "$HOME/.kbd/.keymap_sv"
fi

in regular interactive shell from Fedora/RHEL it won't crash

Proposed patch

This patch fixes the symptom.

The origin of the problem is that unicode is deactivated in the test envirnoment.
