Description

Several vulnerabilities have been discovered in the interpreter for the Python language. The Common Vulnerabilities and Exposures project identifies the following problems :

  • CVE-2007-2052 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.

  • CVE-2007-4965 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.

  • CVE-2008-1721 Justin Ferguson discovered that a buffer overflow in the zlib module may lead to the execution of arbitrary code.

  • CVE-2008-1887 Justin Ferguson discovered that insufficient input validation in PyString_FromStringAndSize() may lead to the execution of arbitrary code.
