Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Memory corruption
EUVDB-ID: #VU11544
Risk: High
CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-15670
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code with elevated privileges on the target system.
The weakness exists in the glob function in glob.c due to off-by-one error. A remote attacker can trigger heap-based buffer overflow and execute arbitrary code with root privileges.
Successful exploitation of the vulnerability may result in system compromise.
Install update from vendor's website.

EUVDB-ID: #VU11546
Risk: High
CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-15804
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists in the glob function in glob.c due to buffer overflow during unescaping of user names with the ~ operator. A remote attacker can trigger memory corruption and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
