audioop input validation¶
The audioop module in Python 2.7 and 3.2 does not verify the relationships
between size arguments and byte string lengths, which allows
context-dependent attackers to cause a denial of service (memory corruption
and application crash) via crafted arguments, as demonstrated by a call to
audioop.reverse() with a one-byte string, a different vulnerability
than CVE-2010-1634.
