TITLE

Python of SSL Module ssl.match_hostname Any in the function SSL Vulnerability impersonating a server

DESCRIPTION

The ssl.match_hostname function in the SSL module in Python 2.6 through 3.4 does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408. SSL A vulnerability that impersonates a server exists. Python is prone to a security-bypass vulnerability because the application fails to properly validate SSL certificates from the server. An attacker can exploit this issue to perform man-in-the-middle attacks or impersonate trusted servers, which will aid in further attacks. ============================================================================ Ubuntu Security Notice USN-1984-1 October 01, 2013 python3.2 vulnerabilities ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.10 - Ubuntu 12.04 LTS Summary: Several security issues were fixed in Python. An attacker could exploit this to cause Python to consume resources, resulting in a denial of service. (CVE-2013-4238) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.10: python3.2 3.2.3-6ubuntu3.4 python3.2-minimal 3.2.3-6ubuntu3.4 Ubuntu 12.04 LTS: python3.2 3.2.3-0ubuntu3.5 python3.2-minimal 3.2.3-0ubuntu3.5 In general, a standard system update will make all the necessary changes. CVE-2014-1912 Ryan Smith-Roberts discovered a buffer overflow in the socket.recvfrom_into() function. For the stable distribution (wheezy), these problems have been fixed in version 2.7.3-6+deb7u2. For the unstable distribution (sid), these problems have been fixed in version 2.7.6-7. We recommend that you upgrade your python2.7 packages.

All rights reserved. Relevant releases/architectures: RHEV Hypervisor for RHEL-6 - noarch 3. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. Upgrade Note: If you upgrade the Red Hat Enterprise Virtualization Hypervisor through the 3.2 Manager administration portal, the Host may appear with the status of "Install Failed". If this happens, place the host into maintenance mode, then activate it again to get the host back to an "Up" state. A buffer overflow flaw was found in the way QEMU processed the SCSI "REPORT LUNS" command when more than 256 LUNs were specified for a single SCSI target. A privileged guest user could use this flaw to corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2013-4344) Multiple flaws were found in the way Linux kernel handled HID (Human Interface Device) reports. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2013-4238) The default OpenSSH configuration made it easy for remote attackers to exhaust unauthorized connection slots and prevent other users from being able to log in to a system. This flaw has been addressed by enabling random early connection drops by setting MaxStartups to 10:30:100 by default. For more information, refer to the sshd_config(5) man page.

This has been fixed, and rhev-hypervisor6 now includes the latest vhostmd package.

Summary: Updated python packages that fix one security issue, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2.

Description: Python is an interpreted, interactive, object-oriented programming language. Note that to exploit this issue, an attacker would need to obtain a carefully crafted certificate signed by an authority that the client trusts. (CVE-2013-4238) These updated python packages include numerous bug fixes and one enhancement. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.5 Technical Notes, linked to in the References, for information on the most significant of these changes. All users of python are advised to upgrade to these updated packages, which fix these issues and add this enhancement. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 5.
