Package: mutt Version: 1.7.2-1 Severity: important Tags: security Dear Maintainer,
for the first time since upgrading to Stretch a few months ago, mutt crashed when I pressed enter on mail -- both when viewing locally as well as via IMAP). Starting up mutt again and trying to display that mail again crashes again, i.e. it seems to be reproducible. Here's a backtrace made from the coredump: #0 strlen () at ../sysdeps/x86_64/strlen.S:106 #1 0x00007fd336bbc895 in __GI__IO_fputs (str=0x0, fp=0x55b6136a45d0) at iofputs.c:33 #2 0x000055b6127122dc in print_smime_keyinfo (msg=0x55b612761572 "Problem signature from:", key=key@entry=0x0, s=s@entry=0x7fff04837490, sig=<optimized out>, sig=<optimized out>) at ../../crypt-gpgme.c:1375 #3 0x000055b61271282c in show_one_sig_status (ctx=ctx@entry=0x55b6134741c0, idx=idx@entry=0, s=s@entry=0x7fff04837490) at ../../crypt-gpgme.c:1491 #4 0x000055b61271332c in verify_one (s=0x7fff04837490, tempfile=<optimized out>, is_smime=<optimized out>, sigbdy=<optimized out>, sigbdy=<optimized out>) at ../../crypt-gpgme.c:1576 #5 0x000055b61269717e in mutt_signed_handler (a=0x55b61384f900, a@entry=0x55b61386e800, s=s@entry=0x7fff04837490) at ../../crypt.c:1005 #6 0x000055b6126bf119 in run_decode_and_handler (b=b@entry=0x55b61386e800, s=s@entry=0x7fff04837490, handler=handler@entry=0x55b612696d40 <mutt_signed_handler>, plaintext=plaintext@entry=0) at ../../handler.c:1697 #7 0x000055b6126bf481 in mutt_body_handler (b=b@entry=0x55b61386e800, s=s@entry=0x7fff04837490) at ../../handler.c:1842 #8 0x000055b6126a05fb in _mutt_copy_message (fpout=fpout@entry=0x55b6136a45d0, fpin=0x55b6136b9150, hdr=hdr@entry=0x55b61386e260, body=0x55b61386e800, flags=flags@entry=2124, chflags=<optimized out>, chflags@entry=262294) at ../../copy.c:695 #9 0x000055b6126a0b6b in mutt_copy_message (fpout=0x55b6136a45d0, src=0x55b612f7bb50, hdr=hdr@entry=0x55b61386e260, flags=flags@entry=2124, chflags=262294) at ../../copy.c:783 #10 0x000055b6126987c8 in mutt_display_message (cur=0x55b61386e260) at ../../commands.c:159 #11 0x000055b6126a7f0c in mutt_index_menu () at ../../curs_main.c:2041 #12 0x000055b612688f16 in main (argc=1, argv=<optimized out>, environ=<optimized out>) at ../../main.c:896 Thunderbird can display the mail and says that the S/MIME signature is not valid. In case the backtrace above does not suffice to find the issue, I can probably provide the mail in private. I'm not 100% sure if this might be a security issue. It is at least usable as DOS against mutt users and mutt crashes on input received from untrusted sources. No idea if that might be used for remote code execution or similar. So to be on the safe side, I'm tagging this as "security". Security team: Please remove this tag if you think that this issue does not validate further investigation from a security point of view. -- Package-specific info:
