This perl update fixes a race condition in rmtree. (CVE-2008-5302)

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2010-0458 advisory.

    - CVE-2008-5302 - use latest patch without Cwd module
    - CVE-2008-5302 perl: File::Path rmtree race condition (CVE-2005-0448)       reintroduced after upstream rebase to 5.8.8-1
    - CVE-2010-1168 perl Safe: Intended restriction bypass via object references
    - CVE-2010-1447 Safe 2.26 and earlier: Intended restriction bypass via Perl       object references in code executed outside safe compartment

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Multiple vulnerabilities has been discovered and corrected in Path.pm and Safe.pm which could lead to escalated privilegies (CVE-2008-5302, CVE-2008-5303, CVE-2010-1168, CVE-2010-1447). The updated packages have been patched to correct these issues.

Jonathan Smith discovered that the Archive::Tar Perl module did not correctly handle symlinks when extracting archives. If a user or automated system were tricked into opening a specially crafted tar file, a remote attacker could over-write arbitrary files.
(CVE-2007-4829)

Tavis Ormandy and Will Drewry discovered that Perl did not correctly handle certain utf8 characters in regular expressions. If a user or automated system were tricked into using a specially crafted expression, a remote attacker could crash the application, leading to a denial of service. Ubuntu 8.10 was not affected by this issue.
(CVE-2008-1927)

A race condition was discovered in the File::Path Perl module's rmtree function. If a local attacker successfully raced another user's call of rmtree, they could create arbitrary setuid binaries. Ubuntu 6.06 and 8.10 were not affected by this issue. (CVE-2008-5302)

A race condition was discovered in the File::Path Perl module's rmtree function. If a local attacker successfully raced another user's call of rmtree, they could delete arbitrary files. Ubuntu 6.06 was not affected by this issue. (CVE-2008-5303).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Paul Szabo rediscovered a vulnerability in the File::Path::rmtree function of Perl. It was possible to exploit a race condition to create setuid binaries in a directory tree or remove arbitrary files when a process is deleting this tree. This issue was originally known as CVE-2005-0448 and CVE-2004-0452, which were addressed by DSA-696-1 and DSA-620-1. Unfortunately, they were reintroduced later.

Updated perl packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Perl is a high-level programming language commonly used for system administration utilities and web programming. The Safe extension module allows users to compile and execute Perl code in restricted compartments. The File::Path module allows users to create and remove directory trees.

The Safe module did not properly restrict the code of implicitly called methods (such as DESTROY and AUTOLOAD) on implicitly blessed objects returned as a result of unsafe code evaluation. These methods could have been executed unrestricted by Safe when such objects were accessed or destroyed. A specially crafted Perl script executed inside of a Safe compartment could use this flaw to bypass intended Safe module restrictions. (CVE-2010-1168)

The Safe module did not properly restrict code compiled in a Safe compartment and executed out of the compartment via a subroutine reference returned as a result of unsafe code evaluation. A specially crafted Perl script executed inside of a Safe compartment could use this flaw to bypass intended Safe module restrictions, if the returned subroutine reference was called from outside of the compartment.
(CVE-2010-1447)

Multiple race conditions were found in the way the File::Path module's rmtree function removed directory trees. A malicious, local user with write access to a directory being removed by a victim, running a Perl script using rmtree, could cause the permissions of arbitrary files to be changed to world-writable and setuid, or delete arbitrary files via a symbolic link attack, if the victim had the privileges to change the permissions of the target files or to remove them. (CVE-2008-5302, CVE-2008-5303)

Red Hat would like to thank Tim Bunce for responsibly reporting the CVE-2010-1168 and CVE-2010-1447 issues. Upstream acknowledges Nick Cleaton as the original reporter of CVE-2010-1168, and Tim Bunce and Rafael Garcia-Suarez as the original reporters of CVE-2010-1447.

These packages upgrade the Safe extension module to version 2.27.
Refer to the Safe module's Changes file, linked to in the References, for a full list of changes.

Users of perl are advised to upgrade to these updated packages, which correct these issues. All applications using the Safe or File::Path modules must be restarted for this update to take effect.

The remote host is affected by the vulnerability described in GLSA-201311-17 (Perl: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Perl. Please review the       CVE identifiers referenced below for details.
  Impact :

    A local attacker could cause a Denial of Service condition or perform       symlink attacks to overwrite arbitrary files with the privileges of the       user running the application. A context-dependent attacker could cause a       Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

NOTE: SL 50-52 x86_64 releases originally had a perl.i386 package. It was taken out of the x86_64 SL5 distribution and is not part of this security update. If you have one of these earlier SL5 x86_64 distributions and your perl update does not work due to conflicts, you should do a 'yum remove perl.i386' before doing your update on these earlier SL 5 x86_64 releases.

USN-700-1 fixed vulnerabilities in Perl. Due to problems with the Ubuntu 8.04 build, some Perl .ph files were missing from the resulting update. This update fixes the problem. We apologize for the inconvenience.
