CVE-2017-3735

TITLE

OpenSSL Vulnerabilities in incorrect certificate text

DESCRIPTION

While parsing an IPAddressFamily extension in an X.509 certificate, it is possible to do a one-byte overread. This would result in an incorrect text display of the certificate. This bug has been present since 2006 and is present in all versions of OpenSSL before 1.0.2m and 1.1.0g. OpenSSL is prone to a security-bypass vulnerability. Successfully exploiting this issue will allow attackers to bypass security restrictions and perform unauthorized actions; this may aid in launching further attacks. Summary: Security Advisory 2. Description: Red Hat Ansible Tower 3.3.1 is now available and contains the following bug fixes: - - Fixed event callback error when in-line vaulted variables are used with ``include_vars`` - - Fixed HSTS and X-Frame-Options to properly be set in nginx configuration - - Fixed isolated node setup to no longer fail when ``ansible_host`` is used - - Fixed selection of custom virtual environments in job template creation - - Fixed websockets for job details to properly work - - Fixed the ``/api/v2/authtoken`` compatibility shim - - Fixed page size selection on the jobs screen - - Fixed instances in an instance group to properly be disabled in the user interface - - Fixed the job template selection in workflow creation to properly render - - Fixed ``member_attr`` to properly set on some LDAP configurations during upgrade, preventing login - - Fixed ``PosixUIDGroupType`` LDAP configurations - - Improved the RAM requirement in the installer preflight check - - Updated Tower to properly report an error when relaunch was used on a set of failed hosts that is too large - - Updated sosreport configuration to gather more python environment, nginx, and supervisor configuration - - Fixed display of extra_vars for scheduled jobs 3. Solution: The Ansible Tower Upgrade and Migration Guide is available at: https://docs.ansible.com/ansible-tower/latest/html/upgrade-migration-guide/ index.html 4. ========================================================================== Ubuntu Security Notice USN-3611-2 April 17, 2018 openssl vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 ESM Summary: Several security issues were fixed in OpenSSL. This update provides the corresponding update for Ubuntu 12.04 ESM. (CVE-2017-3735) It was discovered that OpenSSL incorrectly handled certain ASN.1 types. A remote attacker could possibly use this issue to cause a denial of service. (CVE-2018-0739) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 ESM: libssl1.0.0 1.0.1-4ubuntu5.40 openssl 1.0.1-4ubuntu5.40 After a standard system update you need to reboot your computer to make all the necessary changes. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 APPLE-SA-2017-12-6-1 macOS High Sierra 10.13.2, Security Update 2017-002 Sierra, and Security Update 2017-005 El Capitan macOS High Sierra 10.13.2, Security Update 2017-002 Sierra, and Security Update 2017-005 El Capitan are now available and address the following: apache Available for: macOS High Sierra 10.13.1, macOS Sierra 10.12.6, OS X El Capitan 10.11.6 Impact: Processing a maliciously crafted Apache configuration directive may result in the disclosure of process memory Description: Multiple issues were addressed by updating to version 2.4.28.
