Description

This security bulletin contains information about 1 security vulnerability.


1) Security restrictions bypass (CVE-ID: CVE-2013-2929)

The vulnerability allows a local unauthenticated attacker to obtain potentially sensitive information and bypass security restrictions on the target system.

The weakness exists due to improper use of the get_dumpable function. A local attacker can gain access to potentially sensitive information from IA64 scratch registers via a crafted application, related to kernel/ptrace.c and arch/ia64/include/asm/processor.h, or bypass intended ptrace restrictions.
