"The remote Solaris system is missing necessary patches to address
security updates :

  - Race condition in the rmtree function in the File::Path
    module in Perl 5.6.1 and 5.8.4 sets read/write
    permissions for the world, which allows local users to
    delete arbitrary files and directories, and possibly
    read files and directories, via a symlink attack.
    (CVE-2004-0452)

  - Buffer overflow in the PerlIO implementation in Perl
    5.8.0, when installed with setuid support (sperl),
    allows local users to execute arbitrary code by setting
    the PERLIO_DEBUG variable and executing a Perl script
    whose full pathname contains a long directory tree.
    (CVE-2005-0156)

  - Race condition in the rmtree function in File::Path.pm
    in Perl before 5.8.4 allows local users to create
    arbitrary setuid binaries in the tree being deleted, a
    different vulnerability than CVE-2004-0452.
    (CVE-2005-0448)

  - Untrusted search path vulnerability in Perl before
    5.8.7-r1 on Gentoo Linux allows local users in the
    portage group to gain privileges via a malicious shared
    object in the Portage temporary build directory, which
    is part of the RUNPATH. (CVE-2005-4278)

  - Integer overflow in the regular expression engine in
    Perl 5.8.x allows context-dependent attackers to cause a
    denial of service (stack consumption and application
    crash) by matching a crafted regular expression against
    a long string. (CVE-2010-1158)

  - Off-by-one error in the decode_xs function in
    Unicode/Unicode.xs in the Encode module before 2.44, as
    used in Perl before 5.15.6, might allow
    context-dependent attackers to cause a denial of service
    (memory corruption) via a crafted Unicode string, which
    triggers a heap-based buffer overflow. (CVE-2011-2939)

  - CGI.pm module before 3.63 for Perl does not properly
    escape newlines in (1) Set-Cookie or (2) P3P headers,
    which might allow remote attackers to inject arbitrary
    headers into responses from applications that use
    CGI.pm. (CVE-2012-5526)"
