Debian DSA-063-1 : xinetd - change default umask

high Nessus Plugin ID 14900
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

zen-parse reported on bugtraq that there is a possible buffer overflow in the logging code from xinetd. This could be triggered by using a fake identd that returns special replies when xinetd does an ident request.

Another problem is that xinetd sets it umask to 0. As a result any programs that xinetd start that are not careful with file permissions will create world-writable files.

Both problems have been fixed in version 2.1.8.8.p3-1.1.

Solution

Upgrade the affected xinetd package.
