The wuftpd package as shipped with SuSE Linux distributions comes with two versions of wuftpd: wuftpd-2.4.2, installed as /usr/sbin/wuftpd, and wuftpd-2.6.0, installed as /usr/sbin/wuftpd-2.6. The admin decides which version to use by the inetd/xinetd configuration.

The Cyrus SASL library provides an authentication API for mail clients and servers. A format bug was found in one of the logging functions, that could be used by an attacker to gain access to a machine or to acquire higher privileges.

The susehelp package contains several CGI-scripts to provide a flexible help-system to the user. Some of these scripts open files in an insecure manner, thus allowing remote attackers to execute arbitrary commands as wwwrun-user on the server running susehelp package. These bugs have been fixed in the newly available packages. Please update your susehelp package immediately if present on your system.

We have received reports that the "SSH CRC-32 compensation attack detector vulnerability" is being actively exploited. This is the same integer type error previously corrected for OpenSSH in DSA-027-1. OpenSSH (the Debian ssh package) was fixed at that time, but ssh-nonfree and ssh-socks were not.

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.

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.
