Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU11546
Risk: High
CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
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.
MitigationInstall update from vendor's website.

2) Memory corruption
EUVDB-ID: #VU11544
Risk: High
CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
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.
