    CVE Id(s)      : CVE-2007-2052 CVE-2007-4965 CVE-2008-1679 CVE-2008-1721 CVE-2008-1887
    Several vulnerabilities have been discovered in the interpreter for the
    Python language. The Common Vulnerabilities and Exposures project identifies
    the following problems:
        Piotr Engelking discovered that the strxfrm() function of the locale
        module miscalculates the length of an internal buffer, which may
        result in a minor information disclosure.
        It was discovered that several integer overflows in the imageop
        module may lead to the execution of arbitrary code, if a user is
        tricked into processing malformed images. This issue is also
        tracked as CVE-2008-1679 due to an initially incomplete patch.
        Justin Ferguson discovered that a buffer overflow in the zlib
        module may lead to the execution of arbitrary code.
        Justin Ferguson discovered that insufficient input validation in
        PyString_FromStringAndSize() may lead to the execution of arbitrary
    For the stable distribution (etch), these problems have been fixed in
    version 2.5-5+etch1.
    For the unstable distribution (sid), these problems have been fixed in
    version 2.5.2-3.
    We recommend that you upgrade your python2.5 packages.
