Description

This security bulletin contains information about 2 vulnerabilities.


1) Memory leak (CVE-ID: CVE-2018-18443)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to memory leak within ThreadPool in IlmBase/IlmThread/IlmThreadPool.cpp, as demonstrated by exrmultiview. A remote attacker can perform a denial of service attack.


2) Out-of-bounds write (CVE-ID: CVE-2018-18444)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input in the exrmultiview in makeMultiView.cpp. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
