Red Hat Network Satellite Server version 4.2.3 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 various 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 was discovered. An attacker could create a carefully-crafted compressed stream that would cause an application to crash if the stream is opened by a user. (CVE-2005-2096). An attacker could create a carefully crafted compressed stream that would cause an application to crash if the stream is opened by a user. (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 is used it may be possible for an attacker to 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 could allow an attacker, acting as a "man in the middle" 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 can result in an infinite loop which consumed system memory (CVE-2006-2937). Certain public key types can take disproportionate amounts of time to process in OpenSSL, leading to a denial of service. (CVE-2006-2940) A flaw was discovered in the way that the Python repr() function handled UTF-32/UCS-4 strings. If an application written in Python 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 Python application. (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 may possibly cause disclosure of data stored in the memory of a Python application using this function. (CVE-2007-2052) Multiple integer overflow flaws were discovered in Python's imageop module. If an application written in Python 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.
