Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Memory corruption
EUVDB-ID: #VU15507
Risk: High
CVSSv3.1: 8.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-12389
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
Update the affected package to version: 1:60.3.0-1~deb9u1
Vulnerable software versionsDebian Linux: All versions
External linkshttp://www.debian.org/security/2018/dsa-4337
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.

3) Poor event handling
EUVDB-ID: #VU15490
Risk: High
CVSSv3.1: 8.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-12392
CWE-ID:
CWE-388 - Error Handling
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to poor event handling when manipulating user events in nested loops while opening a document through script. A remote attacker can trick the victim into visiting a specially crafted website and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.

CVE-ID: CVE-2018-12393
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to integer overflow during the conversion of scripts to an internal UTF-16 representation. A remote attacker can trick the victim into visiting a specially crafted website, trigger out-of-bounds write and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
