Published: 2018-04-26

Vulnerability identifier: #VU12205

Vulnerability risk: Low

CVSSv3.1: 5.2 [CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2013-2929

CWE-ID: CWE-264

Exploitation vector: Local

Exploit availability: No

Vulnerable software:
Linux kernel
Operating systems & Components / Operating system

Vendor: Linux Foundation

Description
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.

Mitigation
Update to version 3.12.2.

Vulnerable software versions

Linux kernel: 3.12 - 3.12.1, 3.11 - 3.11.10
