"It was discovered that OpenSSL could be made to dereference a NULL
pointer when processing S/MIME messages. A remote attacker could use
this to cause a denial of service. These issues did not affect Ubuntu
8.04 LTS. (CVE-2006-7250, CVE-2012-1165)

Tavis Ormandy discovered that OpenSSL did not properly perform bounds
checking when processing DER data via BIO or FILE functions. A remote
attacker could trigger this flaw in services that used SSL to cause a
denial of service or possibly execute arbitrary code with application
privileges. (CVE-2012-2110).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

    parsing certain MIME headers. (CVE-2006-7250)

  - The fix for CVE-2011-4619 was not complete.

  - An error exists in the Cryptographic Message Syntax
    (CMS) and PKCS #7 implementation such that data can
    be decrypted using Million Message Attack (MMA)
    adaptive chosen cipher text attack. (CVE-2012-0884)

  - An error exists in the function 'mime_param_cmp' in the
    file 'crypto/asn1/asn_mime.c' that can allow a NULL
    pointer to be dereferenced when handling certain S/MIME
    content. (CVE-2012-1165)

those using CMS, PKCS #7 and S/MIME decryption operations are."
