Debian DSA-2283-1 : krb5-appl - programming error

medium Nessus Plugin ID 55673
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

Tim Zingelmann discovered that due an incorrect configure script the kerborised FTP server failed to set the effective GID correctly, resulting in privilege escalation.

The oldstable distribution (lenny) is not affected.

Solution

Upgrade the krb5-appl packages.

For the stable distribution (squeeze), this problem has been fixed in version 1.0.1-1.1.
