CVE-2007-4772 (2008-01-09)

The regular expression parser in TCL before 8.4.17, as used in PostgreSQL 8.2 before 8.2.6, 8.1 before 8.1.11, 8.0 before 8.0.15, and 7.4 before 7.4.19, allows context-dependent attackers to cause a denial of service (infinite loop) via a crafted regular expression.

CVE-2007-6067 (2008-01-09)

Algorithmic complexity vulnerability in the regular expression parser in TCL before 8.4.17, as used in PostgreSQL 8.2 before 8.2.6, 8.1 before 8.1.11, 8.0 before 8.0.15, and 7.4 before 7.4.19, allows remote authenticated users to cause a denial of service (memory consumption) via a crafted "complex" regular expression with doubly-nested states.

libpng before 1.6.32 does not properly check the length of chunks against the user limit.

NAME

Tk::Submethods - add aliases for tk sub-commands

SYNOPSIS

use Tk::Submethods ( 'command1' => [qw(sub1 sub2 sub3)],
                     'command2' => [qw(sub1 sub2 sub3)]);

DESCRIPTION

Creates ->commandSub(...) as an alias for ->command('sub',...) e.g. ->grabRelease for ->grab('release').

For each command/subcommand pair this creates a closure with command and subcommand as bound lexical variables and assigns a reference to this to a 'glob' in the callers package.

Someday the sub-commands may be created directly in the C code.
