Subject: OpenServer 5.0.6 OpenServer 5.0.7 : OpenSSL Multiple
Vulnerabilities
Advisory number: SCOSA-2004.10
Issue date: 2004 July 29
Cross reference: sr890284 fz529412 erg712603 TA04-078A VU#288574
VU#465542 CAN-2004-0079 CAN-2004-0081 CAN-2004-0112
______________________________________________________________________________
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
----------------------------------------------------------------------
