Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
1) Privilege escalation
EUVDB-ID: #VU5553
Risk: Medium
CVSSv3.1: 8.4 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:H/RL:O/RC:C]
CVE-ID: CVE-2015-1701
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to improper access control. A local attacker can create a specially crafted application, execute a callback in userspace and use data from the System token to execute arbitrary code on the system with root privileges.
Successful exploitation of the vulnerability may result in arbitrary code execution on the vulnerable system.
Note: the vulnerability was being actively exploited.Mitigation
