USN-70-1: Perl DBI module vulnerability

26 January 2005

libdbi-perl vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 4.10

Software Description

Details

Javier Fern�ndez-Sanguino Pe�a from the Debian Security Audit Project discovered that the module DBI::ProxyServer in Perl’s DBI library created a PID file in an insecure manner. This could allow a symbolic link attack to create or overwrite arbitrary files with the privileges of the user invoking a program using this module (like ‘dbiproxy’).

Now the module does not create a such a PID file by default.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 4.10
libdbi-perl

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
