Summary

KPPP 2.1.2 in KDE 3.1.5 and earlier, when setuid root without certain wrappers, does not properly close a privileged file descriptor for a domain socket, which allows local users to read and write to /etc/hosts and /etc/resolv.conf and gain control over DNS name resolution by opening a number of file descriptors before executing kppp.

    descriptionThe KDE team fixed a bug in kppp in 2002 which was now discovered to be exploitable by iDEFENSE. By opening a sufficiently large number of file descriptors before executing kppp which is installed setuid root a local attacker is able to take over privileged file descriptors.

    descriptionUpdated kdenetwork packages that fix a file descriptor leak are now available. This update has been rated as having low security impact by the Red Hat Security Response Team The kdenetwork packages contain a collection of networking applications for the K Desktop Environment. A bug was found in the way kppp handles privileged file descriptors. A malicious local user could make use of this flaw to modify the /etc/hosts or /etc/resolv.conf files, which could be used to spoof domain information. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-0205 to this issue. Please note that the default installation of kppp on Red Hat Enterprise Linux uses consolehelper and is not vulnerable to this issue. However, the kppp FAQ provides instructions for removing consolehelper and running kppp suid root, which is a vulnerable configuration. Users of kdenetwork should upgrade to these updated packages, which contain a backported patch, and are not vulnerable to this issue.

titlezend_hash_del_key_or_index in zend_hash.c in PHP before 4.4.3 and 5.x before 5.1.3 can cause zend_hash_del to delete the wrong element, which prevents a variable from being unset even when the PHP unset function is called, which might cause the variable's value to be used in security-relevant operations.
