New submission from Christian Heimes: In Python/frozenmain.c the function Py_FrozenMain() doesn't handle argv_copy and argv_copy2 correctly. Both variables contain memory that is allocated with PyMem_Malloc(). argv_copy2 is never checked for NULL and both variables are not correctly cleaned up in error cases.
CID 486834: Resource leak (RESOURCE_LEAK)At (11): Variable "argv_copy" going out of scope leaks the storage it points to. CID 486835: Resource leak (RESOURCE_LEAK)At (9): Variable "argv_copy2" going out of scope leaks the storage it points to. Suggested fix: Separate var declaration from PyMem_Malloc() calls and use a goto label to clean up the variables and its content at the end of the function. ---------- components: Interpreter Core messages: 170139 nosy: christian.heimes priority: normal severity: normal status: open title: Py_FrozenMain() resource leak and missing malloc checks type: behavior versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15893> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
