Description Remi Collet 2014-01-01 07:58:23 UTC

From fann_error.c

   errstr = (char *) malloc(FANN_ERRSTR_MAX);
   vsprintf(errstr, ...

This is obviously broken as there is no length check.

Switching to vsnprintf seems mandatory.


Ex, runnning test suite for pecl/fann

In fann_stdio.c
fann_error(NULL, FANN_E_WRONG_CONFIG_VERSION, configuration_file);

Message: Wrong version of configuration file, aborting read of configuration file "%s"
Option:  /home/rpmbuild/SPECS/remirepo/php/pecl/php-pecl-fann/fann-1.0.6/tests/fann_create_from_file_invalid.tmp

This is about 180 char, so > FANN_ERRSTR_MAX (128)

Comment 2 Remi Collet 2014-01-01 08:06:35 UTC

Notice: there is also a memory leak, as in some case the malloced buffer is not freed.

Comment 3 Remi Collet 2014-01-01 08:40:19 UTC

Created attachment 844054 [details]
0001-fix-memory-corruption-in-fann_error-1047627.patch

git format-patch

Fix proposal (need to be reported upstream).

Comment 4 Remi Collet 2014-01-01 18:21:12 UTC

I sent the proposed patch to upstream, but also notice this was already reported, see https://github.com/libfann/fann/pull/2 (the fix is different)

Comment 5 Tomas Smetana 2014-01-08 09:15:31 UTC

Hi Remi,
  thanks a lot for the patch.  I took a look at the other proposed fix [1] by bukka and it seems the differences are merely cosmetic or have negligible impact.  I will use your patch as is for now.
