A sequence of processor instructions can lead to unexpected behavior in some Intel processors, potentially allowing an authenticated user to enable escalation of privilege, information disclosure, or denial of service via local access. This issue is related to the interpretation of redundant prefixes and can cause the system to crash or become unresponsive. The vulnerability, termed Reptar, primarily affects multi-tenant virtualized environments where multiple virtual machines are run on the same host.

The issue involves multiple vulnerabilities in various packages of the openSUSE operating system, including systemtap, libvmtools, and others, which can lead to disruption of protected information. These vulnerabilities can be exploited remotely. Additionally, a race condition in the ptrace functionality of the Linux kernel before version 3.7.5 allows local users to gain privileges via a crafted application.
