Debian DSA-696-1 : perl - design flaw

low Nessus Plugin ID 17600
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

Paul Szabo discovered another vulnerability in the File::Path::rmtree function of perl, the popular scripting language. When a process is deleting a directory tree, a different user could exploit a race condition to create setuid binaries in this directory tree, provided that he already had write permissions in any subdirectory of that tree.

Solution

Upgrade the perl packages.

For the stable distribution (woody) this problem has been fixed in version 5.6.1-8.9.
