Description

This security bulletin contains information about 1 security vulnerability.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2013-2930)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The perf_trace_event_perm function in kernel/trace/trace_event_perf.c in the Linux kernel before 3.12.2 does not properly restrict access to the perf subsystem, which allows local users to enable function tracing via a crafted application.
