Description Michael Harrison 2012-02-28 18:34:46 UTC
A vulnerability has been reported in OpenSSL, which can be exploited by malicious people to cause a DoS (Denial of Service) of the application using the library.

The vulnerability is caused due to a NULL-pointer dereference error in the "mime_hdr_cmp()" function (crypto/asn1/asn_mime.c) when parsing certain MIME headers and can be exploited to cause a crash.

The vulnerability is reported in versions 0.9.7i, 0.9.8t, and 1.0.0g. Other versions may also be affected.

Fixed in the CVS repository.

Provided and/or discovered by
Reported by Mats Nilsson to the openssl-dev mailing list.

Sorry guys, this is not my fault.

> Ok did some more research and here's what we got:
> First mention of this bug is in 2006:
> So please use CVE-2006-7248 for this issue.

Due to the Novell/kadu miss-paste this CVE needs to be re-issued. Please
use CVE-2006-7250 for this OpenSSL issue.

CVE-2006-7250 (
  The mime_hdr_cmp function in crypto/asn1/asn_mime.c in OpenSSL 0.9.8t and
  earlier allows remote attackers to cause a denial of service (NULL pointer
  dereference and application crash) via a crafted S/MIME message.
Comment 3 SpanKY gentoo-dev 2012-03-12 18:01:46 UTC
openssl 1.0.0h and 0.9.8u now in the tree which should fix this
Comment 4 Tim Sammut (RETIRED) gentoo-dev 2012-03-12 21:28:30 UTC
Looks like this is relevant too:

OpenSSL Security Advisory [12 Mar 2012]

CMS and S/MIME Bleichenbacher attack (CVE-2012-0884)

A weakness in the OpenSSL CMS and PKCS #7 code can be exploited
using Bleichenbacher's attack on PKCS #1 v1.5 RSA padding
also known as the million message attack (MMA).

Only users of CMS, PKCS #7, or S/MIME decryption operations are affected. A
successful attack needs on average 2^20 messages. In practice only automated
systems will be affected as humans will not be willing to process this many

SSL/TLS applications are *NOT* affected by this problem since the 
SSL/TLS code does not use the PKCS#7 or CMS decryption code. 

Thanks to Ivan Nestlerode <> for discovering
this weakness.

The fix was developed by Stephen Henson of the OpenSSL core team.

Affected users should upgrade to OpenSSL 1.0.0h or 0.9.8u.

CVE-2012-1165 (
  The mime_param_cmp function in crypto/asn1/asn_mime.c in OpenSSL before
  0.9.8u and 1.x before 1.0.0h allows remote attackers to cause a denial of
  service (NULL pointer dereference and application crash) via a crafted
  S/MIME message, a different vulnerability than CVE-2006-7250.

CVE-2012-0884 (
  The implementation of Cryptographic Message Syntax (CMS) and PKCS #7 in
  OpenSSL before 0.9.8u and 1.x before 1.0.0h does not properly restrict
  certain oracle behavior, which makes it easier for context-dependent
  attackers to decrypt data via a Million Message Attack (MMA) adaptive chosen
  ciphertext attack.
