CVE-1999-0462 (1999-03-17)

suidperl in Linux Perl does not check the nosuid mount option on file systems, allowing local users to gain root access by placing a setuid script in a mountable file system, e.g. a CD-ROM or floppy disk.

CVE-2000-0703 (2000-10-20)

suidperl (aka sperl) does not properly cleanse the escape sequence "~!" before calling /bin/mail to send an error report, which allows local users to gain privileges by setting the "interactive" environmental variable and calling suidperl with a filename that contains the escape sequence.

CVE-2023-47039 (2023-10-30)

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.

CVE-2016-1238 (2016-08-02)

(period) characters from the end of the includes directory array, which might allow local users to gain privileges via a Trojan horse module under the current working directory.

CVE-2015-8608 (2017-02-07)

The VDir::MapPathA and VDir::MapPathW functions in Perl 5.22 allow remote attackers to cause a denial of service (out-of-bounds read) and possibly execute arbitrary code via a crafted (1) drive letter or (2) pInName argument.

NAME

ExtUtils::Manifest - utilities to write and check a MANIFEST file

SYNOPSIS

require ExtUtils::Manifest;

ExtUtils::Manifest::mkmanifest;

ExtUtils::Manifest::manicheck;

ExtUtils::Manifest::filecheck;

ExtUtils::Manifest::fullcheck;

ExtUtils::Manifest::skipcheck;

ExtUtild::Manifest::manifind();

ExtUtils::Manifest::maniread($file);

ExtUtils::Manifest::manicopy($read,$target,$how);

DESCRIPTION

Mkmanifest() writes all files in and below the current directory to a file named in the global variable $ExtUtils::Manifest::MANIFEST (which defaults to MANIFEST) in the current directory. It works similar to

find . -print

but in doing so checks each line in an existing MANIFEST file and includes any comments that are found in the existing MANIFEST file in the new one. Anything between white space and an end of line within a MANIFEST file is considered to be a comment. Filenames and comments are seperated by one or more TAB characters in the output. All files that match any regular expression in a file MANIFEST.SKIP (if such a file exists) are ignored.

Manicheck() checks if all the files within a MANIFEST in the current directory really do exist. It only reports discrepancies and exits silently if MANIFEST and the tree below the current directory are in sync.

Filecheck() finds files below the current directory that are not mentioned in the MANIFEST file. An optional file MANIFEST.SKIP will be consulted. Any file matching a regular expression in such a file will not be reported as missing in the MANIFEST file.

Fullcheck() does both a manicheck() and a filecheck().

Skipcheck() lists all the files that are skipped due to your MANIFEST.SKIP file.

Manifind() retruns a hash reference. The keys of the hash are the files found below the current directory.

Maniread($file) reads a named MANIFEST file (defaults to MANIFEST in the current directory) and returns a HASH reference with files being the keys and comments being the values of the HASH. Blank lines and lines which start with # in the MANIFEST file are discarded.

Manicopy($read,$target,$how) copies the files that are the keys in the HASH %$read to the named target directory. The HASH reference $read is typically returned by the maniread() function. This function is useful for producing a directory tree identical to the intended distribution tree. The third parameter $how can be used to specify a different methods of "copying". Valid values are cp, which actually copies the files, ln which creates hard links, and best which mostly links the files but copies any symbolic link to make a tree without any symbolic link. Best is the default.

MANIFEST.SKIP

The file MANIFEST.SKIP may contain regular expressions of files that should be ignored by mkmanifest() and filecheck(). The regular expressions should appear one on each line. Blank lines and lines which start with # are skipped. Use \# if you need a regular expression to start with a sharp character. A typical example:

\bRCS\b
^MANIFEST\.
^Makefile$
~$
\.html$
\.old$
^blib/
^MakeMaker-\d

EXPORT_OK

&mkmanifest, &manicheck, &filecheck, &fullcheck, &maniread, and &manicopy are exportable.

GLOBAL VARIABLES

$ExtUtils::Manifest::MANIFEST defaults to MANIFEST. Changing it results in both a different MANIFEST and a different MANIFEST.SKIP file. This is useful if you want to maintain different distributions for different audiences (say a user version and a developer version including RCS).

$ExtUtils::Manifest::Quiet defaults to 0. If set to a true value, all functions act silently.

DIAGNOSTICS

All diagnostic output is sent to STDERR.

Not in MANIFEST: file

is reported if a file is found, that is missing in the MANIFEST file which is excluded by a regular expression in the file MANIFEST.SKIP.

No such file: file

is reported if a file mentioned in a MANIFEST file does not exist.

MANIFEST: $!

is reported if MANIFEST could not be opened.

Added to MANIFEST: file

is reported by mkmanifest() if $Verbose is set and a file is added to MANIFEST. $Verbose is set to 1 by default.

SEE ALSO

ExtUtils::MakeMaker which has handy targets for most of the functionality.
