Advisories MDVSA-2010:215: python

[paul]

Multiple vulnerabilities was discovered and corrected in python:

 

Buffer underflow in the rgbimg module in Python 2.5 allows remote

attackers to cause a denial of service (application crash) via a large

ZSIZE value in a black-and-white (aka B/W) RGB image that triggers

an invalid pointer dereference (CVE-2009-4134).

 

Integer overflow in rgbimgmodule.c in the rgbimg module in Python

2.5 allows remote attackers to have an unspecified impact via a large

image that triggers a buffer overflow. NOTE: this vulnerability exists

because of an incomplete fix for CVE-2008-3143.12 (CVE-2010-1449).

 

Multiple buffer overflows in the RLE decoder in the rgbimg module in

Python 2.5 allow remote attackers to have an unspecified impact via an

image file containing crafted data that triggers improper processing

within the (1) longimagedata or (2) expandrow function (CVE-2010-1450).

 

The asyncore module in Python before 3.2 does not properly handle

unsuccessful calls to the accept function, and does not have

accompanying documentation describing how daemon applications should

handle unsuccessful calls to the accept function, which makes it

easier for remote attackers to conduct denial of service attacks that

terminate these applications via network connections (CVE-2010-3492).

 

Multiple race conditions in smtpd.py in the smtpd module in Python 2.6,

2.7, 3.1, and 3.2 alpha allow remote attackers to cause a denial of

service (daemon outage) by establishing and then immediately closing

a TCP connection, leading to the accept function having an unexpected

return value of None, an unexpected value of None for the address,

or an ECONNABORTED, EAGAIN, or EWOULDBLOCK error, or the getpeername

function having an ENOTCONN error, a related issue to CVE-2010-3492

(CVE-2010-3493).
