Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Security restrictions bypass
EUVDB-ID: #VU12205
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 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe 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.

2) Information disclosure
EUVDB-ID: #VU9883
Risk: Low
CVSSv3.1: 5 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:P/RL:O/RC:C]
CVE-ID: CVE-2017-5715
CWE-ID:
CWE-200 - Information exposure
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information.
The vulnerability exists in Intel CPU hardware due to improper implementation of the speculative execution of instructions. A local attacker can utilize branch target injection, execute arbitrary code, perform a side-channel attack and read sensitive memory information.
