CVE-2006-7250 openssl: mime_hdr_cmp NULL dereference crash
Last modified: 2016-03-04 06:16:50 EST
"openssl smime -verify -in" verifies the signature of the input file and
the "-verify" switch expects a signed or encrypted input file. Previously,
running openssl on an S/MIME file that was not encrypted or signed caused
openssl to segfault. With this update, the input file is now checked for a
signature or encryption. Consequently, openssl now returns an error and
quits when attempting to verify an unencrypted or unsigned S/MIME file.
This was fixed in RHSA-2009:1335:

openssl PR: 2711 Tolerate bad MIME headers in parser
Patch is from RHEL-6 OpenSSL source RPM
This problem was previously reported via (private) bug #472440 and addressed as non-security bug fix in Red Hat Enterprise Linux 5 packages in 2009 via RHSA-2009:1335:
This patch was also included in openssl and openssl098e packages in Red Hat Enterprise Linux 6 since the initial release. It's also included in current Fedora packages. Patch is names as openssl-*-bad-mime.patch
Later in 2012, it was discovered that the fix was previously not pushed upstream and that was done via:
and applied upstream in:
http://cvs.openssl.org/chngview?cn=22147 (cvs head)
and cn 22144, 22145, 22146 for commits to 0.9.8, 1.0.0 and 1.0.1 branches
There was some confusion around CVE assignment due to a use of the CVE in unrelated bug report:
CVE-2006-7248 was previously used for this issue.
This issue was corrected in Red Hat Enterprise Linux 5 via RHSA-2009:1335. It did not affect openssl packages shipped with Red Hat Enterprise Linux 6.
