Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU10874
Risk: Low
CVSSv3.1: 3.5 [CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2014-10072
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a local unauthenticated attacker to cause DoS condition on the target system.
The weakness exists in the utils.c source code file due to buffer overflow. A local attacker can trigger memory corruption and cause the service to crash.
Install update from vendor's website.

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) Buffer overflow
EUVDB-ID: #VU10855
Risk: Low
CVSSv3.1: 3.5 [CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-18206
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to cause DoS condition on the target system.
The weakness exists in the utils.c source code file due to insufficient checks on buffer lengths for symlink expansion. A local attacker can send specially crafted input, trigger memory corruption and cause the service to crash.

3) Buffer overflow
EUVDB-ID: #VU11349
Risk: Low
CVSSv3.1: 7.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-1083
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists in the compctl.c source code file due to insufficient bounds checking on the PATH_MAX-sized buffer used for file completion candidates. A local attacker can create a malicious directory path, trick the victim into using the autocomplete functionality to traverse the path, trigger buffer overflow and execute arbitrary code with root privileges.
Successful exploitation of the vulnerability may result in system compromise.

4) Stack-based buffer overflow
EUVDB-ID: #VU11771
Risk: Low
CVSSv3.1: 7.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-1100
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The vulnerability exists due to stack-based buffer overflow in the utils.c:checkmailpath function. A local attacker can trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
