Jukka Taimisto, Tero Rontti and Rauli Kaksonen discovered that the embedded Expat copy in the interpreter for the Python language, does not properly process malformed or crafted XML files. (CVE-2009-3560 CVE-2009-3720 ) This vulnerability could allow an attacker to cause a denial of service while parsing a malformed XML file.
In addition, this update fixes an integer overflow in the hashlib module in python2.5. This vulnerability could allow an attacker to defeat cryptographic digests. (CVE-2008-2316 ) It only affects the oldstable distribution (etch).
