Fedora Legacy Update Advisory
Synopsis: Updated perl packages fix security issues
Advisory ID: FLSA:152845
Issue date: 2006-01-24
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
CVE Names: CVE-2004-0452 CVE-2004-0976 CVE-2005-0155
CVE-2005-0156 CVE-2005-0448

---------------------------------------------------------------------
1. Topic:
Updated perl packages that fix several security flaws are now available.
Perl is a high-level programming language commonly used for system
administration utilities and Web programming.
2. Relevant releases/architectures:
Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386
Fedora Core 2 - i386
3. Problem description:
An unsafe file permission bug was discovered in the rmtree() function in
the File::Path module. The rmtree() function removes files and
directories in an insecure manner, which could allow a local user to
read or delete arbitrary files. The Common Vulnerabilities and
Exposures project has assigned the name CVE-2004-0452 to this issue.
Solar Designer discovered several temporary file bugs in various Perl
modules. A local attacker could overwrite or create files as the user
running a Perl script that uses a vulnerable module. The Common Vulner-
abilities and Exposures project has assigned the name CVE-2004-0976 to
this issue.
Kevin Finisterre discovered a stack based buffer overflow flaw in sperl,
the Perl setuid wrapper. A local user could create a sperl executable
script with a carefully created path name, overflowing the buffer and
leading to root privilege escalation. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2005-0156 to
this issue.
Kevin Finisterre discovered a flaw in sperl which can cause debugging
information to be logged to arbitrary files. By setting an environment
variable, a local user could cause sperl to create, as root, files with
arbitrary filenames, or append the debugging information to existing
files. The Common Vulnerabilities and Exposures project has assigned
the name CVE-2005-0155 to this issue.
Paul Szabo discovered a bug in the way Perl's File::Path::rmtree module
removed directory trees. If a local user has write permissions to a
subdirectory within the tree being removed by File::Path::rmtree, it is
possible for them to create setuid binary files. The Common Vulner-
abilities and Exposures project has assigned the name CVE-2005-0448 to
this issue. (This issue updates CVE-2004-0452).
Users of perl are advised to upgrade to these packages which contain
backported patches and are not vulnerable to these issues.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which
are not installed but included in the list will not be updated. Note
that you can also use wildcards (*.rpm) if your current directory *only*
contains the desired RPMs.
Please note that this update is also available via yum and apt. Many
people find this an easier way to apply updates. To use yum issue:
yum update
or to use apt:
apt-get update; apt-get upgrade
This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system. This assumes that you
have yum or apt-get configured for obtaining Fedora Legacy content.
Please visit http://www.fedoralegacy.org/docs for directions on how to
configure yum and apt-get.
