Package: perl
Vulnerability: unsafe Safe compartment
OpenPKG Specific: no

Dependent Packages: none

Affected Releases: Affected Packages: Corrected Packages:
OpenPKG 1.0 <= perl-5.6.1-1.0.1 >= perl-5.6.1-1.0.2
OpenPKG 1.1 <= perl-5.6.1-1.1.0 >= perl-5.6.1-1.1.1
OpenPKG CURRENT <= perl-5.8.0-20021129 >= perl-5.8.0-20021216

Description:
Andreas Jurenda discovered [0] a security hole in Safe.pm for Perl
[1]. When a Safe compartment has already been used, there's no
guarantee that it's safe any longer, because there's a way for code
executed within the Safe compartment to alter its operation mask.
Programs that use a Safe compartment only once aren't affected by this
bug.

Check whether you are affected by running "<prefix>/bin/rpm -q perl".
If you have an affected version of the Perl package (see above),
please upgrade it according to the solution below.

Solution:
Update existing packages to newly patched versions of Perl. Select the
updated source RPM appropriate for your OpenPKG release [2][3][4], and
fetch it from the OpenPKG FTP service or a mirror location. Verify its
integrity [5], build a corresponding binary RPM from it and update your
OpenPKG installation by applying the binary RPM [6]. For the latest
OpenPKG 1.1 release, perform the following operations to permanently fix
the security problem (for other releases adjust accordingly).

$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/1.1/UPD
ftp> get perl-5.6.1-1.1.1.src.rpm
ftp> bye
$ <prefix>/bin/rpm -v --checksig perl-5.6.1-1.1.1.src.rpm
$ <prefix>/bin/rpm --rebuild perl-5.6.1-1.1.1.src.rpm
$ su -
# <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/perl-5.6.1-1.1.1.*.rpm
