Synopsis: Low: boost security and bug fix update
Issue Date: 2012-02-21
CVE Numbers: CVE-2008-0171
 CVE-2008-0172

The boost packages provide free, peer-reviewed, portable C++ source
libraries with emphasis on libraries which work well with the C++ Standard
Library.

Invalid pointer dereference flaws were found in the way the Boost regular
expression library processed certain, invalid expressions. An attacker able
to make an application using the Boost library process a specially-crafted
regular expression could cause that application to crash or, potentially,
execute arbitrary code with the privileges of the user running the
application. (CVE-2008-0171)

NULL pointer dereference flaws were found in the way the Boost regular
expression library processed certain, invalid expressions. An attacker able
to make an application using the Boost library process a specially-crafted
regular expression could cause that application to crash. (CVE-2008-0172)

This update also fixes the following bugs:

* Prior to this update, the construction of a regular expression object
could fail when several regular expression objects were created
simultaneously, such as in a multi-threaded program. With this update, the
object variables have been moved from the shared memory to the stack. Now,
the constructing function is thread safe.

* Prior to this update, header files in several Boost libraries contained
preprocessor directives that the GNU Compiler Collection (GCC) 4.4 could
not handle. This update instead uses equivalent constructs that are
standard C.

All users of boost are advised to upgrade to these updated packages, which
fix these issues.
