Sun Java JRE Multiple Vulnerabilities (244986 et al) (Unix)
Critical Nessus Plugin ID 64828
The remote Unix host contains a runtime environment that is affected by multiple vulnerabilities.
The version of Sun Java Runtime Environment (JRE) installed on the remote host is earlier than 6 Update 11 / 5.0 Update 17 / 1.4.2_19 / 1.3.1_24. Such versions are potentially affected by the following security issues : - The JRE creates temporary files with insufficiently random names. (244986) - There are multiple buffer overflow vulnerabilities involving the JRE's image processing code, its handling of GIF images, and its font processing. (244987) - It may be possible for an attacker to bypass security checks due to the manner in which it handles the 'non-shortest form' of UTF-8 byte sequences. - There are multiple security vulnerabilities in Java Web Start and Java Plug-in that may allow for privilege escalation. (244988) - The JRE Java Update mechanism does not check the digital signature of the JRE that it downloads. (244989) - A buffer overflow may allow an untrusted Java application that is launched through the command line to elevate its privileges. (244990) - A vulnerability related to deserializing calendar objects may allow an untrusted applet or application to elevate its privileges. (244991) - A buffer overflow affects the 'unpack200' JAR unpacking utility and may allow an untrusted applet or application to elevate its privileges with unpacking applets and Java Web Start applications. (244992) - The UTF-8 decoder accepts encodings longer than the 'shortest' form. Although not a vulnerability per se, it may be leveraged to exploit software that relies on the JRE UTF-8 decoder to reject the 'non-shortest form' sequence. (245246) - An untrusted applet or application may be able to list the contents of the home directory of the user running the applet or application. (246266) - A denial of service vulnerability may be triggered when the JRE handles certain RSA public keys. (246286) - A vulnerability may be triggered while authenticating users through Kerberos and lead to a system-wide denial of service due to excessive consumption of operating system resources. (246346) - Security vulnerabilities in the JAX-WS and JAXB packages where internal classes can be accessed may allow an untrusted applet or application to elevate privileges. (246366) - An untrusted applet or application when parsing zip files may be able to read arbitrary memory locations in the process that the applet or application is running. (246386) - The JRE allows code loaded from the local filesystem to access localhost. (246387)
Update to Sun Java JDK / JRE 6 Update 11, JDK / JRE 5.0 Update 17, SDK / JRE 1.4.2_19, or SDK / JRE 1.3.1_24 or later and remove, if necessary, any affected versions.
