Advisory number: SCOSA-2005.7
Issue date: 2005 January 20

1. Problem Description

OpenSSL implements the Secure Sockets Layer (SSL) and
Transport Layer Security (TLS) protocols and includes a
general purpose cryptographic library. SSL and TLS are
commonly used to provide authentication, encryption,
integrity, and non-repudiation services to network
applications including HTTP, IMAP, POP3, SMTP, and LDAP.

The U.K. National Infrastructure Security Co-ordination
Centre (NISCC) and the OpenSSL Project have reported several
vulnerabilities in the OpenSSL SSL/TLS library (libssl).
Any application or system that uses this library may be
affected.

CERT Vulnerability Note VU#288574
OpenSSL contains null-pointer assignment in do_change_cipher_spec()
function

The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2004-0079 to this issue.

CERT Vulnerability Note VU#465542
OpenSSL does not properly handle unknown message types

The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2004-0081 to this issue.

CERT Vulnerability Note VU#484726
OpenSSL does not adequately validate length of Kerberos ticket
during SSL/TLS handshake.

The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2004-0112 to this issue.

2. Vulnerable Supported Versions

System Binaries
----------------------------------------------------------------------
UnixWare 7.1.4 Not vulnerable
UnixWare 7.1.3 Distribution
UnixWare 7.1.1 Distribution


3. Solution

The proper solution is to install the latest packages.

4. UnixWare 7.1.3

4.1 Location of Fixed Binaries

ftp://ftp.sco.com/pub/updates/UnixWare/SCOSA-2005.7

4.2 Verification

MD5 (openssl.pkg) = d2ba4c1dee05dad681b39bfea4d4d7f9
MD5 (openssld.pkg) = 6a737b8d0265e8194f55f39518380bae

md5 is available for download from
ftp://ftp.sco.com/pub/security/tools


4.3 Installing Fixed Binaries

Upgrade the affected binaries with the following sequence:

Download openssl.pkg to the /var/spool/pkg directory

# pkgadd -d /var/spool/pkg/openssl.pkg


5. UnixWare 7.1.1

5.1 Location of Fixed Binaries

ftp://ftp.sco.com/pub/updates/UnixWare/SCOSA-2005.7

The fixes are also available in SCO UnixWare Release 7.1.1
Maintenance Pack 5 or later. See
ftp://ftp.sco.com/pub/unixware7/uw711pk/uw711mp5.txt

5.2 Verification

MD5 (openssl.pkg) = d2ba4c1dee05dad681b39bfea4d4d7f9
MD5 (openssld.pkg) = 6a737b8d0265e8194f55f39518380bae

md5 is available for download from
ftp://ftp.sco.com/pub/security/tools


5.3 Installing Fixed Binaries

Upgrade the affected binaries with the following sequence:

Download openssld.pkg to the /var/spool/pkg directory
