Security Advisories (24)
The bsd_glob function in the File::Glob module for Perl before 5.14.2 allows context-dependent attackers to cause a denial of service (crash) via a glob expression with the GLOB_ALTDIRFUNC flag, which triggers an uninitialized pointer dereference.

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.
Perl 5.10.1 allows context-dependent attackers to cause a denial of service (application crash) via a UTF-8 character with a large, invalid codepoint, which is not properly handled during a regular-expression match.

Integer overflow in the format string functionality (Perl_sv_vcatpvfn) in Perl 5.9.2 and 5.8.6 Perl allows attackers to overwrite arbitrary memory and possibly execute arbitrary code via format string specifiers with large values, which causes an integer wrap and leads to a buffer overflow, as demonstrated using format string vulnerabilities in Perl applications.

Integer underflow in regcomp.c in Perl before 5.20, as used in Apple OS X before 10.10.5 and other products, allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via a long digit string associated with an invalid backreference within a regular expression.

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.

In Perl before 5.38.2, S_parse_uniprop_string in regcomp.c can write to unallocated space because a property name associated with a \p{...} regular expression construct is mishandled. The earliest affected version is 5.30.0.
A heap buffer overflow vulnerability was discovered in Perl. When there are non-ASCII bytes in the left-hand-side of the `tr` operator, `S_do_trans_invmap` can overflow the destination pointer `d`. $ perl -e '$_ = "\x{FF}" x 1000000; tr/\xFF/\x{100}/;' Segmentation fault (core dumped) It is believed that this vulnerability can enable Denial of Service and possibly Code Execution attacks on platforms that lack sufficient defenses.

Perl for Windows relies on the system path environment variable to find the shell (cmd.exe). When running an executable which uses Windows Perl interpreter, Perl attempts to find and execute cmd.exe within the operating system. However, due to path search order issues, Perl initially looks for cmd.exe in the current working directory. An attacker with limited privileges can exploit this behavior by placing cmd.exe in locations with weak permissions, such as C:\ProgramData. By doing so, when an administrator attempts to use this executable from these compromised locations, arbitrary code can be executed.

NAME
Pod::Simple::RTF -- format Pod as RTF
SYNOPSIS
perl -MPod::Simple::RTF -e \
"exit Pod::Simple::RTF->filter(shift)->any_errata_seen" \
thingy.pod > thingy.rtf
DESCRIPTION
This class is a formatter that takes Pod and renders it as RTF, good for viewing/printing in MSWord, WordPad/write.exe, TextEdit, etc.
This is a subclass of Pod::Simple and inherits all its methods.
FORMAT CONTROL ATTRIBUTES
You can set these attributes on the parser object before you call parse_file (or a similar method) on it:
- $parser->head1_halfpoint_size( halfpoint_integer );
- $parser->head2_halfpoint_size( halfpoint_integer );
- $parser->head3_halfpoint_size( halfpoint_integer );
- $parser->head4_halfpoint_size( halfpoint_integer );
-
These methods set the size (in half-points, like 52 for 26-point) that these heading levels will appear as.
- $parser->codeblock_halfpoint_size( halfpoint_integer );
-
This method sets the size (in half-points, like 21 for 10.5-point) that codeblocks ("verbatim sections") will appear as.
- $parser->header_halfpoint_size( halfpoint_integer );
-
This method sets the size (in half-points, like 15 for 7.5-point) that the header on each page will appear in. The header is usually just "modulename p. pagenumber".
- $parser->normal_halfpoint_size( halfpoint_integer );
-
This method sets the size (in half-points, like 26 for 13-point) that normal paragraphic text will appear in.
- $parser->no_proofing_exemptions( true_or_false );
-
Set this value to true if you don't want the formatter to try putting a hidden code on all Perl symbols (as best as it can notice them) that labels them as being not in English, and so not worth spellchecking.
- $parser->doc_lang( microsoft_decimal_language_code )
-
This sets the language code to tag this document as being in. By default, it is currently the value of the environment variable
RTFDEFLANG, or if that's not set, then the value 1033 (for US English).Setting this appropriately is useful if you want to use the RTF to spellcheck, and/or if you want it to hyphenate right.
Here are some notable values:
1033 US English 2057 UK English 3081 Australia English 4105 Canada English 1034 Spain Spanish 2058 Mexico Spanish 1031 Germany German 1036 France French 3084 Canada French 1035 Finnish 1044 Norwegian (Bokmal) 2068 Norwegian (Nynorsk)
If you are particularly interested in customizing this module's output even more, see the source and/or write to me.
