Perl is a cross platform programming language. The DBI is the standard
|
|
database interface module for Perl.

Javier Fernandez-Sanguino Pena discovered that the DBI library creates
|
|
temporary files in an insecure, predictable way (CAN-2005-0077). Paul
|
|
Szabo found out that "File::Path::rmtree" is vulnerable to various race
|
|
conditions (CAN-2004-0452, CAN-2005-0448).

<impact type="normal">
|
|
<p>
|
|
A local attacker could create symbolic links in the temporary files
|
|
directory that point to a valid file somewhere on the filesystem. When
|
|
the DBI library or File::Path::rmtree is executed, this could be used
|
|
to overwrite or remove files with the rights of the user calling these
|
|
functions.

There are no known workarounds at this time.

All Perl users should upgrade to the latest version:

|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose dev-lang/perl</code>
