RHBA-2015:0338 - Bug Fix Advisory

Topic

Updated perl packages that fix several bugs are now available for Red Hat
Enterprise Linux 7.

Description

Perl is a high-level programming language that is commonly used for system
administration utilities and web programming.

This update fixes the following bugs:

• Previously, when building the perl packages on the little-endian variant of

IBM Power Systems, the resulting RPM packages installed 64-bit libraries into
the /usr/lib/ directory. With this update, the perl packages have been modified
to store RPM packages in the /usr/lib64/ directory. As a result, the perl
packages built on the little-endian variant of IBM Power Systems now conform to
the file system layout conventions. (BZ#1061792)

• Prior to his update, executing perl upstream tests while FIPS mode was

enabled led to tests failures. To fix this bug, the t/op/crypt.t test has been
modified to use SHA-256 hash algorithm if the default algorithm is not
available. Now, all perl upstream tests run in FIPS-enabled environment pass.
(BZ#1084796)

• When creating threads after tying a variable to an SDBM database using the

SDBM_File Perl module, the Perl interpreter terminated unexpectedly when
terminating Perl threads. With this update, GDBM_File, NDBM_File, ODBM_File, and
SDBM_File Perl modules have been modified to destroy their objects only from the
thread context which created the objects. As a result, the destructors of the
aforementioned file objects are now thread-safe.

Note, however, that other operations on the objects cannot be called from other
threads. In general, the DB_File, GDBM_File, NDBM_File, ODBM_File, and SDBM_File
Perl modules remain thread-unsafe. (BZ#1107542)

• Previously, when running the cpan utility for the first time while the

perl-Time-HiRes and perl-local-lib packages were not installed, cpan terminated
unexpectedly because Time::HiRes or local::lib Perl modules were not available.
To fix this bug, run-time dependency on perl(Time::HiRes) has been added into
the perl packages and run-time dependency on perl(local::lib) has been added
into the perl-CPAN package. Now, when cpan is installed, it pulls in all needed
dependencies. (BZ#1122368)

Users of perl are advised to upgrade to these updated packages, which fix these
bugs.
