perl-5.10.1-119.AXS4

Perl is a high-level programming language with roots in C, sed, awk and shell scripting. Perl is good at handling processes and files, and is especially good at handling text. Perl's hallmarks are practicality and efficiency. While it is used to do a lot of different things, Perl's most common applications are system administration utilities and web programming. A large proportion of the CGI scripts on the web are written in Perl. You need the perl package installed on your system so that your system can handle Perl scripts.
Install this package if you want to program in Perl or enable your system to handle Perl scripts.
Security issues fixed with this release:
CVE-2010-2761
The multipart_init function in (1) CGI.pm before 3.50 and (2) Simple.pm in CGI::Simple 1.112 and earlier uses a hardcoded value of the MIME boundary string in multipart/x-mixed-replace content, which allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via crafted input that contains this value, a different vulnerability than CVE-2010-3172.
CVE-2010-4410
CRLF injection vulnerability in the header function in (1) CGI.pm before 3.50 and (2) Simple.pm in CGI::Simple 1.112 and earlier allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via vectors related to non-whitespace characters preceded by newline characters, a different vulnerability than CVE-2010-2761 and CVE-2010-3172.
CVE-2011-1487
The (1) lc, (2) lcfirst, (3) uc, and (4) ucfirst functions in Perl 5.10.x, 5.11.x, and 5.12.x through 5.12.3, and 5.13.x through 5.13.11, do not apply the taint attribute to the return value upon processing tainted input, which might allow context-dependent attackers to bypass the taint protection mechanism via a crafted string.
Fixed bugs:
- Version 3.17 of the Test::Harness distribution removed the support for the fork-based parallel testing, and 'prove' does not support this option any longer. Both the manual page and the output of the "prove --help" command have been updated so that "--fork" is no longer included in the list of available command line options.
- Due to a packaging error, the perl packages did not include the "NDBM_File" module. This has been corrected.
- When using the "threads" module, continual creation and destruction of threads could cause the Perl program to consume an increasing amount of memory and then to leak memory. This has been fixed: the memory is freeed when a thread is destroyed.
- The following error message would appear when a user started the cpan command line interface and attempted to download a distribution from CPAN:
CPAN: checksum security checks disabled because Digest::SHA not installed. Please consider installing the Digest::SHA module.
This was because the perl packages did not require the Digest::SHA module as a dependency. The spec file has been corrected to include perl-Digest-SHA package as a dependency and this error no longer occurs.
- With the "threads" module, sending a signal to a thread that did not have a signal handler specified made the perl interpreter to terminate unexpectedly with a segmentation fault. The "threads" module has been updated to upstream version 1.82, which fixes this bug.
