CVE-2013-1753

The gzip_decode function in the xmlrpc client library in Python 3.4 and earlier allows remote attackers to cause a denial of service (memory consumption) via a crafted HTTP request.

Denial of service flaws due to unbound readline() calls in the imaplib, poplib, and smtplib modules (CVE-2013-1752).

A gzip bomb and unbound read denial of service flaw in python XMLRPC library (CVE-2013-1753).

These are all security issues fixed in the libpython2_7-1_0-2.7.12-1.4 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the python-2.7.18-8.1 package on the GA media of openSUSE Tumbleweed.

The gzip_decode function in the xmlrpc client library in Python 3.4 and earlier allows remote attackers to cause a denial of service (memory consumption) via a crafted HTTP request.

This update to python 2.7.9 fixes the following issues:

• python-2.7-libffi-aarch64.patch: Fix argument passing in libffi for aarch64

From the version update to 2.7.9:

• contains full backport of ssl module from Python 3.4 (PEP466)

• HTTPS certificate validation enabled by default (PEP476)

• SSLv3 disabled by default (bnc#901715)

• backported ensurepip module (PEP477)

• fixes several missing CVEs from last release: CVE-2013-1752, CVE-2013-1753

• dropped upstreamed patches: python-2.7.6-poplib.patch, smtplib_maxline-2.7.patch, xmlrpc_gzip_27.patch

• dropped patch python-2.7.3-ssl_ca_path.patch because we don't need it with ssl module from Python 3

• libffi was upgraded upstream, seems to contain our changes, so dropping libffi-ppc64le.diff as well

• python-2.7-urllib2-localnet-ssl.patch - properly remove unconditional 'import ssl' from test_urllib2_localnet that caused it to fail without ssl

• skip test_thread in qemu_linux_user mode

From the version update to 2.7.8:

• fixes CVE-2014-4650 directory traversal in CGIHTTPServer
• fixes CVE-2014-7185 (bnc#898572) potential buffer overflow in buffer()

Also the DH parameters were increased to 2048 bit to fix logjam security issue (bsc#935856)

This update for python fixes the following issues:

Updated to version 2.7.17 to unify packages among openSUSE:Factory and SLE versions (bsc#1159035).

It was discovered that multiple Python protocol libraries incorrectly limited certain data when connecting to servers. A malicious ftp, http, imap, nntp, pop or smtp server could use this issue to cause a denial of service. (CVE-2013-1752)

It was discovered that the Python xmlrpc library did not limit unpacking gzip-compressed HTTP bodies. A malicious server could use this issue to cause a denial of service. (CVE-2013-1753)

It was discovered that the Python json module incorrectly handled a certain argument. An attacker could possibly use this issue to read arbitrary memory and expose sensitive information. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-4616)

It was discovered that the Python CGIHTTPServer incorrectly handled URL-encoded path separators in URLs. A remote attacker could use this issue to expose sensitive information, or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-4650)

It was discovered that Python incorrectly handled sizes and offsets in buffer functions. An attacker could possibly use this issue to read arbitrary memory and obtain sensitive information. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-7185)
