Ubuntu Security Notice (C) 2012-2013 Canonical, Inc. / NASL script (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

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).

Solution :

Update the affected libssl0.9.8 and / or libssl1.0.0 packages.

Risk factor :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.9
(CVSS2#E:POC/RL:OF/RC:C)
