CVE-2011-1521

原文の説明

The urllib and urllib2 modules in Python 2.x before 2.7.2 and 3.x before 3.2.1 process Location headers that specify redirection to file: URLs, which makes it easier for remote attackers to obtain sensitive information or cause a denial of service (resource consumption) via a crafted URL, as demonstrated by the file:///etc/passwd and file:///dev/zero URLs.

影響を受けるソフトウェア

• Python = 2.6.1= 2.3.3= 3.1.1= 2.1.1= 2.1.2= 2.3.1 完全一致
