While fuzzing Python 3.4.5 with AFL, ASAN and libdislocator, I fat fingered the keyboard ASAN pops up a LeakSanitizer error. Apparently trying to open a non-existent file causes Python 3.4.5 to leak >880KB of memory.

./python: can't open file 'id:000109': [Errno 2] No such file or directory

How are you defining "leak"?  It isn't a leak if Python allocates memory that it doesn't free when doing a new operation.  If you do that operation repeatedly and memory use continues to increase, that would be a leak.
msg273497 - (view) Author: geeknik (geeknik) Date: 2016-08-23 17:57 
Interesting that only Python exhibits this "leaky" behavior that generates a LeakSanitizer error. I don't see similar behavior in Perl, Ruby or PHP. Running a non-ASAN build under Valgrind reports that a leak is still occurring: 

LEAK SUMMARY:

From the Valgrind manual:
"possibly lost" means your program is leaking memory, unless you're doing unusual things with pointers that could cause them to point into the middle of an allocated block;

I'm not saying there isn't a leak, rather I'm trying to understand what you are reporting, without any understanding of ASN.  So I'm going to leave this to others to evaluate.

Also, do you see the same thing in 3.5 or 3.6?  We aren't patching 3.4 anymore (except for security issues).
msg273501 - (view) Author: geeknik (geeknik) Date: 2016-08-23 18:14 
Sure, 3.5 and/or 3.6 has memory leaks during compilation:
https://bugs.python.org/issue27780

And I just compiled 3.5.2 and running that version of python against a non-existent file returns this from LeakSanitizer:

ASAN_SYMBOLIZER_PATH=/usr/lib/llvm-3.5/bin/llvm-symbolizer ASAN_OPTIONS=symbolizer=1 ./python garbage
./python: can't open file 'garbage': [Errno 2] No such file or directory

Looks like this got fixed somewhere along between 3.5 and 3.6


---
3.5
---

./python: can't open file 'id:000109': [Errno 2] No such file or directory

=================================================================
==28078==ERROR: LeakSanitizer: detected memory leak



---
3.6
---

./python id:000109     
./python: can't open file 'id:000109': [Errno 2] No such file or directory


Closing as 3.5 is no longer a supported version.
