Ubuntu 8.04 LTS : openssl vulnerabilities (USN-620-1)

Ubuntu Security Notice (C) 2008-2016 Canonical, Inc. / NASL script (C) 2008-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that OpenSSL was vulnerable to a double-free when
using TLS server extensions. A remote attacker could send a crafted
packet and cause a denial of service via application crash in
applications linked against OpenSSL. Ubuntu 8.04 LTS does not compile
TLS server extensions by default. (CVE-2008-0891)

It was discovered that OpenSSL could dereference a NULL pointer. If a
user or automated system were tricked into connecting to a malicious
server with particular cipher suites, a remote attacker could cause a
denial of service via application crash. (CVE-2008-1672).

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 packages.

Risk factor :

Medium / CVSS Base Score : 4.3
(CVSS2#AV:N/AC:M/Au:N/C:N/I:N/A:P)
CVSS Temporal Score : 3.7
(CVSS2#E:ND/RL:OF/RC:C)
