Ubuntu 8.04 LTS / 10.04 LTS / 11.04 / 11.10 : openssl vulnerabilities (USN-1424-1)

Ubuntu Security Notice (C) 2012-2016 Canonical, Inc. / NASL script (C) 2012-2016 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).

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.

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 : 6.2
(CVSS2#E:F/RL:OF/RC:ND)
Public Exploit Available : true
