Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Out-of-bounds write
EUVDB-ID: #VU8962
Risk: High
CVSSv3.1: 8.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2017-12607
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker can execute arbitrary code on the target system.
The weakness exists due to boundary error in the PPTStyleSheet::PPTStyleSheet functionality. A remote attacker can send a specially crafted .ppt file, trick the victim into opening it, trigger out-of-bounds write and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
Update to version 4.1.4.
