Red Hat Security Advisory 2017-0494-01 – Samba is an open-source implementation of the Server Message Block protocol and the related Common Internet File System protocol, which allow PC-compatible machines to share files, printers, and various information. The following packages have been upgraded to a later upstream version: samba. Security Fix: It was found that Samba always requested forwardable tickets when using Kerberos authentication. A service to which Samba authenticated using Kerberos could subsequently use the ticket to impersonate Samba to other services or domain users.

Red Hat Security Advisory 2017-0484-01 – Red Hat Gluster Storage is a software only scale-out storage solution that provides flexible and affordable unstructured data storage. It unifies data storage and infrastructure, increases performance, and improves availability and manageability to meet enterprise-level storage challenges. The following packages have been upgraded to a later upstream version: glusterfs, redhat-storage-server. Security Fix: It was found that glusterfs-server RPM package would write file with predictable name into world readable /tmp directory. A local attacker could potentially use this flaw to escalate their privileges to root by modifying the shell script during the installation of the glusterfs-server package.

These files usually have the extension .ico or .cur, but they can also be embedded in executables or libraries. Security Fix: Multiple vulnerabilities were found in icoutils, in the wrestool program. An attacker could create a crafted executable that, when read by wrestool, could result in memory corruption leading to a crash or potential code execution.

Red Hat Security Advisory 2017-0838-01 – OpenJPEG is an open source library for reading and writing image files in JPEG2000 format. Security Fix: Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in OpenJPEG. A specially crafted JPEG2000 image could cause an application using OpenJPEG to crash or, potentially, execute arbitrary code. An out-of-bounds read vulnerability was found in OpenJPEG, in the j2k_to_image tool. Converting a specially crafted JPEG2000 file to another format could cause the application to crash or, potentially, disclose some data from the heap.
