Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Privilege escalation

EUVDB-ID: #VU1007

Risk: Low

CVSSv4.0: 4.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2015-3288

CWE-ID: CWE-388 - Error Handling

Exploit availability: No

Description

The vulnerability allows a local user to obtain elevated privileges.
The vulnerability exists due to mishandling of anonymous pages. Triggering writing to page zero via a specially crafted application attacker can gain elevated privileges or cause page tainting.
Successful exploitation of the vulnerability may result in denial of service on the vulnerable system.

Mitigation

Update the affected packages.

Vulnerable software versions

SUSE Linux: 11

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.

2) Memory corruption

EUVDB-ID: #VU7131

Risk: Medium

CVSSv4.0: 8.5 [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-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.

Mitigation

Update the affected packages.
