Summary: the popen api function in tsrm/tsrm_win32.c in php before 5.2.11 and 5.3.x before 5.3.1, when running on certain windows operating systems, allows context-dependent attackers to cause a denial of service (crash) via a crafted (1) "e" or (2) "er" string in the second argument (aka mode), possibly related to the _fdopen function in the microsoft c runtime library. note: this might not cross privilege boundaries except in rare cases in which the mode argument is accessible to an attacker outside of an application that uses the popen function.
