Fedora Core 3 Update: perl-5.8.5-14.FC3
Posted by Benjamin D. Thomas   
Fedora 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. Perl interpreter would cause a segmentation fault when environment changes during the runtime. Code in lib/FindBin contained a regression which caused problems with MRTG software package.

Fedora Update Notification
FEDORA-2005-600

---------------------------------------------------------------------

Product     : Fedora Core 3
Name        : perl
Version     : 5.8.5                      
Release     : 14.FC3                  
Summary     : The Perl programming language.
Description :
Perl is a high-level programming language with roots in C, sed, awk
and shell scripting.  Perl is good at handling processes and files,
and is especially good at handling text.  Perl's hallmarks are
practicality and efficiency.  While it is used to do a lot of
different things, Perl's most common applications are system
administration utilities and web programming.  A large proportion of
the CGI scripts on the web are written in Perl.  You need the perl
package installed on your system so that your system can handle Perl
scripts.

Install this package if you want to program in Perl or enable your
system to handle Perl scripts.

Update Information:

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.

Perl interpreter would cause a segmentation fault when environment 
changes during the runtime. 

Code in lib/FindBin contained a regression which caused problems 
with MRTG software package.

All of the above problems are now fixed in perl-5.8.5-14.FC3. 
Please test as much as you can and report any problems/regressions.
