Debian Jessie DLA-1754-1 Critical Samba Denial Of Service

Various vulnerabilities were discovered in Samba, SMB/CIFS file, print, and login server/client for Unix . Package : samba Version : 2:4.2.14+dfsg-0+deb8u12 CVE ID : CVE-2017-9461 CVE-2018-1050 CVE-2018-1057 CVE-2019-3880 Various vulnerabilities were discovered in Samba, SMB/CIFS file, print, and login server/client for Unix CVE-2017-9461 smbd in Samba had a denial of service vulnerability (fd_open_atomic infinite loop with high CPU usage and memory consumption) due to wrongly handling dangling symlinks. CVE-2018-1050 Samba was vulnerable to a denial of service attack when the RPC spoolss service was configured to be run as an external daemon. Missing input sanitization checks on some of the input parameters to spoolss RPC calls could have caused the print spooler service to crash. CVE-2018-1057 On a Samba 4 AD DC the LDAP server of Samba incorrectly validated permissions to modify passwords over LDAP allowing authenticated users to change any other users' passwords, including administrative users and privileged service accounts (eg Domain Controllers). Thanks to the Ubuntu security team for having backported the rather invasive changeset to Samba in Ubuntu 14.04 (which we could use to patch Samba in Debian jessie LTS). CVE-2019-3880 A flaw was found in the way Samba implemented an RPC endpoint emulating the Windows registry service API. An unprivileged attacker could have used this flaw to create a new registry hive file anywhere they had unix permissions which could have lead to creation of a new file in the Samba share. For Debian 8 "Jessie", these problems have been fixed in version 2:4.2.14+dfsg-0+deb8u12. We recommend that you upgrade your samba packages.

Red Hat Enterprise Linux 6: RHSA-2012-1202-01 Moderate RPC Flaw

Updated libvirt packages that fix one security issue and two bugs 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,. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: libvirt security and bug fix update Advisory ID: RHSA-2012:1202-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2012:1202.html Issue date: 2012-08-23 CVE Names: CVE-2012-3445 ==================================================================== 1. Summary: Updated libvirt packages that fix one security issue and two bugs 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. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - x86_64 3. Description: The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems. A flaw was found in libvirtd's RPC call handling. An attacker able to establish a read-only connection to libvirtd could trigger this flawwith a specially-crafted RPC command that has the number of parameters set to 0, causing libvirtd to access invalid memory and crash. (CVE-2012-3445) This update also fixes the following bugs: * Previously, repeatedly migrating a guest between two machines while using the tunnelled migration could cause the libvirt daemon to lock up unexpectedly. The bug in the code for locking remote drivers has been fixed and repeated tunnelled migrations of domains now work as expected. (BZ#847946) * Previously, when certain system locales were used by the system, libvirt could issue incorrect commands to the hypervisor. This bug has been fixed and the libvirt library and daemon are no longer affected by the choice of the user locale. (BZ#847959) All users of libvirt are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, libvirtd will be restarted automatically. 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/knowledge/articles/11258 5. Bugs fixed (http://bugzilla.redhat.com/): 844734 - CVE-2012-3445 libvirt: crash in virTypedParameterArrayClear 847946 - libvirtd may hang during tunneled migration 6.
