Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Privilege escalation

EUVDB-ID: #VU5553

Risk: Medium

CVSSv4.0: [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Green]

CVE-ID: CVE-2015-1701

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: Yes

Description

The 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

Install update from vendor's website.

Vulnerable software versions

Windows: Vista - 7

Windows Server: 2008

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?

Yes. This vulnerability is being exploited in the wild.

2) Information disclosure

EUVDB-ID: #VU5552

Risk: Low

CVSSv4.0: [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2015-1680

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: Yes

Description

The vulnerabiity allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to private address information leaking during a function call. A remote attacker can bypass the ASLR protection mechanism, gain access to sensitive information and use it to launch further attacks against the affected system.

Successful exploitation of this vulnerability results in information disclosure on the vulnerable system.

Mitigation

Install update from vendor's website.
