Description Jan Lieskovsky 2008-07-11 14:12:41 UTC

Description of problem:

Fix potential integer underflow and overflow conditions in the PyOS_vsnprintf
C API function.

Proposed upstream patch:

http://svn.python.org/view?rev=63883&view=rev

Comment 2 James Antill 2008-07-11 15:00:35 UTC

 Does this do anything if python knows you have a working snprintf()? -- Ahh it
does "str[size-1] = '\0';" even when size == 0? ... can that happen? Do we
really wan tto include all the other parts of the patch, given that we won't be
testing any of it -- and won't use it?

Comment 15 Vincent Danen 2012-02-09 20:20:06 UTC

Description:

Multiple integer underflow and overflow flaws were found in the Python snprintf() wrapper implementation. An attacker could use these flaws to cause a denial of service (memory corruption).
