Description Petr Pisar 2012-04-25 06:53:05 UTC

There is an upstream report that while verifying PGP signature using crypt_use_gpgme=true, one can get segfault if the signature specifies policy URL. In that case gpgme returns NULL signature notation name and mutt passes the NULL to strcmp() which leads to segfault. See <http://dev.mutt.org/trac/ticket/3574> for more details, especially for a reproducer and a proposed fix.

Reproduced with mutt-1.5.21-10.fc17.x86_64 gpgme-1.3.0-8.fc17.x86_64 successfully.

Comment 1 Honza Horak 2012-04-25 08:37:26 UTC

Thanks for the report. Just summarizing steps to reproduce:
1. download archive madduck.tar.gz from [1] and extract it to /tmp/madduck
2. run echo "set crypt_use_gpgme=yes">/tmp/muttrc
3. mutt -f /tmp/madduck -F /tmp/muttrc
4. open the only one message in the mailbox
