RHEL 4 : Solaris client in Satellite Server (RHSA-2008:0629)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Red Hat Network Satellite Server version 5.1.1 is now available. This
update includes fixes for a number of security issues in Red Hat
Network Satellite Server Solaris client components.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

This release corrects several security vulnerabilities in components
shipped as part of the Red Hat Network Satellite Server Solaris
client. In a typical operating environment, these components are not
used by the Satellite Server in a vulnerable manner. These security
updates will reduce risk should these components be used by other
applications.

Several flaws in Zlib were discovered. An attacker could create a
carefully-crafted compressed stream that would cause an application to
crash if the stream was opened by a user. (CVE-2005-2096,
CVE-2005-1849)

A buffer overflow was discovered in the OpenSSL
SSL_get_shared_ciphers() utility function. An attacker could send a
list of ciphers to an application that used this function and overrun
a buffer (CVE-2006-3738).

A flaw in the SSLv2 client code was discovered. If a client
application used OpenSSL to create an SSLv2 connection to a malicious
server, that server could cause the client to crash. (CVE-2006-4343)

An attack on OpenSSL PKCS #1 v1.5 signatures was discovered. Where an
RSA key with exponent 3 was used an attacker could, potentially, forge
a PKCS #1 v1.5 signature that would be incorrectly verified by
implementations that do not check for excess data in the RSA
exponentiation result of the signature. This issue affected
applications that use OpenSSL to verify X.509 certificates as well as
other uses of PKCS #1 v1.5. (CVE-2006-4339)

OpenSSL contained a software work-around for a bug in SSL handling in
Microsoft Internet Explorer version 3.0.2. It is enabled in most
servers that use OpenSSL to provide support for SSL and TLS. This
work-around was vulnerable to a man-in-the-middle attack which allowed
a remote user to force an SSL connection to use SSL 2.0, rather than a
stronger protocol, such as SSL 3.0 or TLS 1.0. (CVE-2005-2969)

During OpenSSL parsing of certain invalid ASN.1 structures, an error
condition was mishandled. This could result in an infinite loop which
consumed system memory (CVE-2006-2937).

Certain public key types could take disproportionate amounts of time
to process in OpenSSL, leading to a denial of service. (CVE-2006-2940)

A flaw was discovered in the Python repr() function's handling of
UTF-32/UCS-4 strings. If an application used the repr() function on
untrusted data, this could lead to a denial of service or, possibly,
allow the execution of arbitrary code with the privileges of the
application using the flawed function. (CVE-2006-4980)

A flaw was discovered in the strxfrm() function of Python's locale
module. Strings generated by this function were not properly
NULL-terminated. This could, potentially, cause disclosure of data
stored in the memory of an application using this function.
(CVE-2007-2052)

Multiple integer overflow flaws were discovered in Python's imageop
module. If an application used the imageop module to process untrusted
images, it could cause the application to crash, enter an infinite
loop, or, possibly, execute arbitrary code with the privileges of the
Python interpreter. (CVE-2007-4965)

A stack-based buffer overflow was discovered in the Python
interpreter, which could allow a local user to gain privileges by
running a script with a long name from the current working directory.
(CVE-2006-1542)

Users of Red Hat Network Satellite Server should upgrade to these
updated packages, which contain backported patches to correct these
issues.
