Software description

Piotr Engelking discovered that strxfrm in Python was not correctly
calculating the size of the destination buffer. This could lead to small
information leaks, which might be used by attackers to gain additional
knowledge about the state of a running Python script. (CVE-2007-2052)

A flaw was discovered in the Python imageop module. If a script using
the module could be tricked into processing a specially crafted set of
arguments, a remote attacker could execute arbitrary code, or cause the
application to crash. (CVE-2007-4965)
