Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Path traversal
EUVDB-ID: #VU41440
Risk: Medium
CVSSv3.1: 6.4 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2014-0475
CWE-ID:
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Multiple directory traversal vulnerabilities in GNU C Library (aka glibc or libc6) before 2.20 allow context-dependent attackers to bypass ForceCommand restrictions and possibly have other unspecified impact via a .. (dot dot) in a (1) LC_*, (2) LANG, or other locale environment variable.
MitigationUpdate the affected packages.
SUSE Linux: 10 - 11

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Command injection
EUVDB-ID: #VU5295
Risk: Critical
CVSSv3.1: 9.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:H/RL:O/RC:C]
CVE-ID: CVE-2014-6271
CWE-ID:
CWE-77 - Command injection
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary commands on the target system.
The vulnerability exists due to incorrect parsing of environment variables. A remote attacker can execute arbitrary code on the target system as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution.
Successful exploitation may allow an attacker to gain complete control over vulnerable system.
Exploitation example:
env x='() { :;}; echo vulnerable' bash -c "echo this is a test"
Note: this vulnerability was being actively exploited in the wild.
MitigationUpdate the affected packages.
