Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Memory corruption
EUVDB-ID: #VU7131
Risk: Medium
CVSSv3.1: 8.2 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:F/RL:O/RC:C]
CVE-ID: CVE-2017-1000364
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: Yes
Description
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The vulnerability exists due to memory management errors in implementation of various functions under multiple operating systems. A local or remote attacker can trigger the affected application to process specially crafted data, trigger memory corruption and execute arbitrary code on the target system. The vulnerability is dubbed by Qualys researchers as “Stack Clash”.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
MitigationUpdate the affected package Slackware 14.1 kernel to version 3.10.107.
Vulnerable software versionsSlackware Linux: 14.1

Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, a fully functional exploit for this vulnerability is available.
2) Security restrictions bypass
EUVDB-ID: #VU7237
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-1000365,CVE-2017-7482
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to bypass security restrictions on the target system.
The weakness exists due to the failure to take the argument and environment strings passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the size) into account when imposing a size restriction. A local attacker can bypass security limitation and perform unauthorized actions.
Successful exploitation of the vulnerability results in access to the system.
Update the affected package Slackware 14.1 kernel to version 3.10.107.
