Debian Security Advisory DSA 488-1 security@debian.org

Package : logcheck
Vulnerability : insecure temporary directory
Problem-Type : local
Debian-specific: no
CVE Ids : CAN-2004-0404

Christian Jaeger reported a bug in logcheck which could potentially be exploited by a local user to overwrite files with root privileges. logcheck utilized a temporary directory under /var/tmp without taking security precautions. While this directory is created when logcheck is installed, and while it exists there is no vulnerability, if at any time this directory is removed, the potential for exploitation exists.

For the current stable distribution (woody) this problem has been fixed in version 1.1.1-13.1woody1.

For the unstable distribution (sid), this problem has been fixed in version 1.1.1-13.2.

We recommend that you update your logcheck package.
