Description Agostino Sarubbo gentoo-dev 2014-03-13 08:55:25 UTC
From ${URL} :

The Debian DSA-2874-1 security advisory (http://www.debian.org/security/2014/dsa-2874) corrected an 
overflow in the mutt mail reader. Analysis of the crash reveals this is likely a heap-based buffer 
overflow in the mutt_copy_hdr() function. Opening a specially-crafted mail message could cause mutt to 
crash or, potentially, execute arbitrary code. The fix looks to be as follows:

+diff -r 3d5e23a66a1a -r 9bf7593e3c08 copy.c
+--- a/copy.c   Thu Oct 24 09:55:36 2013 -0700
++++ b/copy.c   Tue Mar 11 09:40:09 2014 -0700
+@@ -254,6 +254,7 @@
+     {
+       if (!address_header_decode (&this_one))
+       rfc2047_decode (&this_one);
++      this_one_len = mutt_strlen (this_one);
+     }
+     
+     if (!headers[x])
+

(Note as this is copied from the Debian diff, it is actually a one line change of "this_one_len = 
mutt_strlen (this_one);")

From brief testing on Red Hat Enterprise Linux 6, the message's headers had to be viewed (via the "h" 
command) in order to trigger the issue.

CVE-2014-0467 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-0467):
  Buffer overflow in copy.c in Mutt before 1.5.23 allows remote attackers to
  cause a denial of service (crash) via a crafted RFC2047 header line, related
  to address expansion.
