Description Tomas Hoger 2010-05-10 13:52:09 UTC 
Python SVN commit r64114 added integer overflow checks to multiple python module:

  http://svn.python.org/view?view=rev&revision=64114

All the issue got covered under single CVE - CVE-2008-3143.

Checks added to audioop (and rgbimg, see bug #541698) were incorrect and possible to bypass:

Comment 3 Tomas Hoger 2010-05-25 14:27:23 UTC 
Assigning CVE-2010-1634 here and setting priority to low.

As noted in the upstream bug, ulaw2lin, alaw2lin and adpcm2lin integer overflows do not lead to buffer overflows.  lin2lin integer overflow can result in buffer overflow - audioop.lin2lin("A"*0x40000001, 1, 4).  ratecv requires special nchannels argument value rather than special / oversize input.
