DSA-696-1 perl -- design flaw

Debian Security Advisory

DSA-696-1 perl -- design flaw

Date Reported:

22 Mar 2005

Affected Packages:

perl

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 286905, Bug 286922.
In Mitre's CVE dictionary: CVE-2005-0448.

More 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.

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

For the unstable distribution (sid) this problem has been fixed in version 5.8.4-8.

We recommend that you upgrade your perl packages.

Fixed in:

Debian GNU/Linux 3.0 (woody)
