Query regarding python 2.7.11 release
Hi, We are currently using Python 2.6.7 in our product. We have received below vulnerabilities from field: CVE-2014-7185 Integer overflow in bufferobject.c in Python before 2.7.8 allows context-dependent attackers to obtain sensitive information from process memory via a large size and offset in a "buffer" function. CVE-2013-1752 python: multiple unbound readline() DoS flaws in python stdlib CVE-2014-1912 python: buffer overflow in socket.recvfrom_into() CVE-2014-4650 It was discovered that the CGIHTTPServer module incorrectly handled URL encoded paths. A remote attacker could use this flaw to execute scripts outside of the cgi-bin directory, or disclose source of scripts in the cgi-bin directory Currently I can see the 2.7.11 is the latest release as per the below link: https://www.python.org/downloads/ Could you please suggest if the above mentioned vulnerabilities are resolved in the latest release? Regards Gaurav -- https://mail.python.org/mailman/listinfo/python-list
UnicodeDecodeError
I am getting this error while some testing on Python2.6, File "/usr/lib64/python2.6/httplib.py", line 774, in _send_output #msg = "\r\n".join(self._buffer) UnicodeDecodeError: 'ascii' codec can't decode byte 0xe1 in position 14: ordinal not in range(128) I tried the change suggested on this link http://web.archiveorange.com/archive/v/PJbOg9pxJoUpQA9AHp3X, its working fine after that. There seems to be some problem in httplib with unicode handling. I am running it on centos5. I am still not sure why its happening and what will be ideal solution for this? Thanks, Gaurav -- http://mail.python.org/mailman/listinfo/python-list

Re: How to check all elements of a list are same or different
Hi Chris, Thanks for the reply. But I am interested in analysing the contents of just one list. For example, list1=[1,2,3,4,5,6] So, the logical statement would probably be: if list1==(contains all same values), print "Same">False if list1==(contains all different values), print "Different" >True I wanted to know here whether there is a command/function that can do exactly this. I hope I am more clearer than my last try! Thanks!

How to check all elements of a list are same or different
Hi, I am an amateur python user I wanted to know how do I know whether all the contents of a list are all same or all different? Now, I could certainly write a loop with a counter. But is there a ready command for that? Checked a lot of docs and this mailing list, but didnt get anything worthwhile. Would be glad to know. Thanks!

I thought this will achieve 2 things. a) It will escape any unicode character (obviously, I was wrong. Got carried away by the display. I thought \xc2 will get escaped to \\xc2, which is completely preposterous). b) It will make sure that the escape sequences in the string (e.g. '\n') are received by mysql as an escape sequence.

Python 2.4 vs 2.5 - Unicode error
Hi,
I am trying to put some webpages into a mysql database using python
(after some processing on the text). If I use Python 2.4.2, it works
without a fuss. However, on Python 2.5, I get the following error:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position
4357: ordinal not in range(128)
Before sending the (insert) query to the mysql server, I do the
following which I think should've taken care of this problem:
sqlStr = sqlStr.replace('\\', '')
(where sqlStr is the query).
Any suggestions?
Thanks!
Gaurav

Re: converting file formats to txt
Thanks Steven, Actually i wanted a do text processing for my office where I can view all files in the system and use the first three to give a summary of the document. Instead of having somebody actually entering the summary. Seems there is no one code that can act as convertor across formats, i'll have to check out convertors for individual formats.

Hi, I wanted a script that can convert any file format (RTF/DOC/HTML/PDF/PS etc) to text format.

converting file formats to txt
Hi All, Am looking for a python script that can convert fileformats to txt format. Am unable to find anything in python. Currently the InfoCon projects looks pretty good to use, but it is return in java. Thanks and Regards, Gaurav Agarwal -- http://mail.python.org/mailman/listinfo/python-list
