1) Double-free memory error
EUVDB-ID: #VU14490
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-2018-10902
CWE-ID:
CWE-415 - Double Free
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The vulnerability exists due to double-free memory error in snd_rawmidi_input_params() and snd_rawmidi_output_status() in 'rawmidi.c'. A local attacker can gain elevated privileges and execute arbitrary code.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationInstall update from vendor's website.
Vulnerable software versionsData Computing Appliance (DCA): before 3.5.3.0
External linksQ & 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.

2) Stack-based buffer overflow
EUVDB-ID: #VU14448
Risk: Low
CVSSv3.1: 7.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-12327
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: Yes
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 Network Time Protocol Query (ntpq) program and Network Time Protocol daemon (ntpd) when handling malicious input. A local attacker can submit a long string argument for an IPv4 or IPv6 command-line parameter, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
