Trustix Secure Linux Security Advisory #2004-0032
Package name: kerberos5
Summary: buffer overflows in krb5_aname_to_localname
Date: 2004-06-02
Affected versions: Trustix Secure Linux 2.1 Trustix Secure
Enterprise Linux 2
Package description:
(MIT) Kerberos is a network authentication protocol. It is designed
to provide strong authentication for client/server applications by
using secret-key cryptography. A free implementation of this
protocol is available from the Massachusetts Institute of
Technology. Kerberos is available in many commercial products as
well.
Problem description:
The krb5_aname_to_localname() library function contains multiple
buffer overflows which could be exploited to gain unauthorized root
access. Exploitation of these flaws requires an unusual combination
of factors, including successful authentication to a vulnerable
service and a non-default configuration on the target service. (See
MITIGATING FACTORS below.) No exploits are known to exist yet.
Action:
We recommend that all systems with this package installed be
upgraded. Please note that if you do not need the functionality
provided by this package, you may want to remove it from your
system.

Package name: apache
Summary:
Date: 2004-06-02
Affected versions: Trustix Secure Linux 1.5 Trustix Secure Linux
2.0 Trustix Secure Linux 2.1 Trustix Secure Enterprise Linux 2
Package description:
Apache is a full featured web server that is freely available, and
also happens to be the most widely used. Built with loadable
modules (all standard modules enabled). This verion is intended as
a replacement for a standard apache, the configuration files
provided with apache and apache-ssl are unchanged.
Problem description:
Stack-based buffer overflow in the ssl_util_uuencode_binary
function in ssl_util.c for Apache mod_ssl when mod_ssl is
configured to trust the issuing CA, may allow remote attackers to
execute arbitrary code via a client certificate with a long subject
DN.
