- -------------------------------------------------------------------------- Debian Security Advisory DSA-1905-1 [email protected] http://www.debian.org/security/ Nico Golde October 10th, 2009 http://www.debian.org/security/faq
- --------------------------------------------------------------------------

Package : python-django
Vulnerability : insufficient input validation
Problem type : remote
Debian-specific: no
Debian bug : #550457
CVE ID : None yet

The forms library of python-django, a high-level Python web development framework, is using a badly chosen regular expression when validating
email addresses and URLs. An attacker can use this to perform denial
of service attacks (100% CPU consumption) due to bad backtracking
via a specially crafted email address or URL which is validated by the
django forms library.


python-django in the oldstable distribution (etch), is not affected by
this problem.

For the stable distribution (lenny), this problem has been fixed in
version 1.0.2-1+lenny2.

For the testing distribution (squeeze), this problem will be fixed soon.

For the unstable distribution (sid), this problem has been fixed in
version 1.1.1-1.


We recommend that you upgrade your python-django packages.
