Red Hat Security Advisory 2015-0862-01

Red Hat Security Advisory 2015-0862-01 – Red Hat JBoss Operations Network is a middleware management solution that provides a single point of control to deploy, manage, and monitor JBoss Enterprise Middleware, applications, and services. It was discovered that the JBoss Operations Network server did not correctly restrict access to certain remote APIs. A remote, unauthenticated attacker could use this flaw to execute arbitrary Java methods via ServerInvokerServlet or SchedulerService, and possibly exhaust all available disk space via ContentManager.

Red Hat Security Advisory 2015-0863-01

Red Hat Security Advisory 2015-0863-01 – The glibc packages provide the standard C libraries, POSIX thread libraries, standard math libraries, and the Name Server Caching Daemon used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. A buffer overflow flaw was found in the way glibc’s gethostbyname_r() and other related functions computed the size of a buffer when passed a misaligned buffer as input. An attacker able to make an application call any of these functions with a misaligned buffer could use this flaw to crash the application or, potentially, execute arbitrary code with the permissions of the user running the application.

Red Hat Security Advisory 2015-0864-01 – The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way seunshare, a utility for running executables under a different security context, used the capng_lock functionality of the libcap-ng library. The subsequent invocation of suid root binaries that relied on the fact that the setuid() system call, among others, also sets the saved set-user-ID when dropping the binaries’ process privileges, could allow a local, unprivileged user to potentially escalate their privileges on the system. Note: the fix for this issue is the kernel part of the overall fix, and introduces the PR_SET_NO_NEW_PRIVS functionality and the related SELinux exec transitions support.
