Description

This security bulletin contains information about 6 vulnerabilities.


1) Use-after-free error (CVE-ID: CVE-2018-4932)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/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 execute arbitrary code on the target system.

The weakness exists due to use-after-free error when handling malicious input. A remote attacker can trick the victim into opening a specially crafted .swf file, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in system compromise.

2) Out-of-bounds read (CVE-ID: CVE-2018-4933)

CWE-ID: CWE-125 - Out-of-bounds read

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


The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to out-of-bounds read when handling malicious input. A remote attacker can trick the victim into opening a specially crafted .swf file, trigger memory corruption and access arbitrary files.

3) Out-of-bounds read (CVE-ID: CVE-2018-4934)

CWE-ID: CWE-125 - Out-of-bounds read

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


The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to out-of-bounds read when handling malicious input. A remote attacker can trick the victim into opening a specially crafted .swf file, trigger memory corruption and access arbitrary files.

4) Out-of-bounds write (CVE-ID: CVE-2018-4935)

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

CVSSv4: CVSS:4.0/AV:N/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 execute arbitrary code on the target system.

The weakness exists due to out-of-bounds write when handling malicious input. A remote attacker can trick the victim into opening a specially crafted .swf file, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in system compromise.

5) Heap-based buffer overflow (CVE-ID: CVE-2018-4936)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

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


The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to heap-based buffer overflow when handling malicious input. A remote attacker can trick the victim into opening a specially crafted .swf file, trigger memory corruption and access arbitrary files.

6) Out-of-bounds write (CVE-ID: CVE-2018-4937)

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

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