Due to the kernel used in the Red Hat Linux 7.1 Korean installation program, some files are written by the installation program with the wrong permissions. It is recommended that all users of the Red Hat Linux 7.1 Korean installation program use the update disk image. If users have already installed, they should check their systems and fix the permissions on the affected files. They can do this by installing the updated redhat-release package.

The webalizer is a widely used tool for analyzing web server logs and produce statistics in HTML format. An exploitable bug was found in webalizer which allows a remote attacker to execute commands on other client machines or revealing sensitive information by placing HTML tags in the right place. This is possible due to missing sanity checks on untrusted data - hostnames and search keywords in this case - that are received by webalizer. This kind of attack is also known as "Cross-Site Scripting Vulnerability". Additionally the untrusted data will be written to files on the server running webalizer; this may lead to further problems when using this data as input for third-party software/scripts.

Syncookies are used to protect a system against certain Denial Of Service (DOS) attacks. A flaw in this mechanism has been found which can be used to circumvent certain types of firewall configurations. Note: syncookies are not enabled in the default installation of Red Hat Linux but many server administrators do enable syncookies.

UUCP is a well known tool suite for copying data between unix-like systems. Zen-Parse reported that the higher privileges of uux (UID uucp) aren't dropped if long options instead of normal (short) options are used. An attacker could exploit this hole, by specifying a malicious configuration file to execute and/or access arbitrary data with the privilege of user uucp.

The squid proxy server can be crashed with a malformed request, resulting in a denial of service attack. After the crash, the squid proxy must be restarted. The weakness can only be triggered from an address that is allowed to send requests, as configured in the squid configuration file.

When used in a spooling environment, it is inappropriate to allow programs to read arbitrary files as a result of print requests. Ghostscript, a postscript interpreter, can read arbitrary system files with the same permissions as the print spooler, potentially exposing the system to an information compromise.

Two security related problems have been found in both the 2.2 and 2.4 series kernels:
