Description Agostino Sarubbo gentoo-dev 2013-12-24 12:03:27 UTC
From ${URL} :

Multiple denial of service flaws were reported against various parts of Python's stdlib:

* httplib [1] (fixed in 2.7.4 [2], 2.6.9 [3], and 3.3.3 [4])
* ftplib [5] (fixed in 2.7.6 [6], 2.6.9 [7], 3.3.3 [8])
* imaplib [9] (not yet fixed in 2.7.x, fixed in 2.6.9 [10], 3.3.3 [11])
* nntplib [12] (fixed in 2.7.6 [13], 2.6.9 [14], 3.3.3 [15])
* poplib [16] (not yet fixed in 2.7.x, fixed in 2.6.9 [17], 3.3.3 [18])
* smtplib [19] (not yet fixed in 2.7.x, fixed in 2.6.9 [20], not yet fixed in 3.3.x)

Unfortunately, upstream assigned a single CVE to all of these, however I do not believe they can 
all use the same CVE due to them being fixed across so many different versions (2.6.9, 2.7.4, 
2.7.6, 3.3.3, as well as future 2.7.x and 3.3.x versions).  So this will likely require MITRE to 
detangle.

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

+  Bump for security bug 495224.

I don't have any objection to stabilizing 2.7.6 and 3.3.3. There seem to be a few unpatched issues in 2.7.6, however.
