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.

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

Family: Ubuntu Local Security Checks
