From Jeffrey Morlan:
pst_parse_block misreads Table Contexts (aka "type 2") with a
multi-block Row Matrix ("ind2"). Rows are never split between blocks -
every block except the last has padding at the end which should be
ignored. I've only seen this affect the recipients table, but
presumably it could affect attachments too. This was causing
out-of-bounds memory ranges to be returned from pst_getBlockOffset and
later access; patch fixes both the table reading issue and adds a
missing bounds check to pst_getBlockOffset (so as not to risk a
segfault if the PST is corrupted).

# =========================================================================== # http://autoconf-archive.cryp.to/ax_python.html # =========================================================================== # # SYNOPSIS # # AX_PYTHON # # DESCRIPTION # # This macro does a complete Python development environment check. # # It recurses through several python versions (from 2.1 to 2.5 in this # version), looking for an executable. When it finds an executable, it # looks to find the header files and library. # # It sets PYTHON_BIN to the name of the python executable, # PYTHON_INCLUDE_DIR to the directory holding the header files, and # PYTHON_LIB to the name of the Python library. # # This macro calls AC_SUBST on PYTHON_BIN (via AC_CHECK_PROG), # PYTHON_INCLUDE_DIR and PYTHON_LIB. # # LAST MODIFICATION # # 2008-04-12 # # COPYLEFT # # Copyright (c) 2008 Michael Tindal # # This program is free software; you can redistribute it and/or modify it # under the terms of the GNU General Public License as published by the # Free Software Foundation; either version 2 of the License, or (at your # option) any later version. # # This program is distributed in the hope that it will be useful, but # WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
