Test ID:1.3.6.1.4.1.25623.1.0.61497
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-620-1 (openssl)
Summary:Ubuntu USN-620-1 (openssl)
Description:
The remote host is missing an update to openssl
announced via advisory USN-620-1.

A security issue affects the following Ubuntu releases:

Ubuntu 8.04 LTS

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

Details follow:

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)

Solution:
The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 8.04 LTS:
libssl0.9.8 0.9.8g-4ubuntu3.3

After a standard system upgrade you need to reboot your computer to
effect the necessary changes.
