Ubuntu 6.06 LTS / 6.10 / 7.04 : openssl vulnerabilities (USN-522-1)

Ubuntu Security Notice (C) 2007-2013 Canonical, Inc. / NASL script (C) 2007-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that OpenSSL did not correctly perform Montgomery
multiplications. Local attackers might be able to reconstruct RSA
private keys by examining another user's OpenSSL processes.
(CVE-2007-3108)

Moritz Jodeit discovered that OpenSSL's SSL_get_shared_ciphers
function did not correctly check the size of the buffer it was writing
to. A remote attacker could exploit this to write one NULL byte past
the end of an application's cipher list buffer, possibly leading to
arbitrary code execution or a denial of service. (CVE-2007-5135).

Solution :

Update the affected packages.

Risk factor :

Critical / CVSS Base Score : 10.0
