Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2020-9899)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the Wi-Fi subsystem. A local user can run a specially crafted program to trigger memory corruption and execute arbitrary code with elevated privileges.
2) Security restrictions bypass (CVE-ID: CVE-2020-9898)
The vulnerability allows a local application to bypass sandbox restrictions.
The vulnerability exists due to application does not properly impose security restrictions within WebDav implementation. A sandboxed process can circumvent sandbox restrictions.
3) Buffer overflow (CVE-ID: CVE-2020-9892)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the OS kernel subsystem. A local user can run a specially crafted program to trigger memory corruption and execute arbitrary code with elevated privileges.
4) Out-of-bounds write (CVE-ID: CVE-2020-9887)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing JPEG images within the AppleVPA framework. A remote attacker can create a specially crafted JPEG file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
5) Buffer overflow (CVE-ID: CVE-2020-9985)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing USD files within the Model I/O subsystem. A remote attacker can create a specially crafted USD file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Buffer overflow (CVE-ID: CVE-2020-9940)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing USD files within the Model I/O subsystem. A remote attacker can create a specially crafted USD file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Buffer overflow (CVE-ID: CVE-2020-9882)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing USD files within the Model I/O subsystem. A remote attacker can create a specially crafted USD file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
8) Buffer overflow (CVE-ID: CVE-2020-9881)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing USD files within the Model I/O subsystem. A remote attacker can create a specially crafted USD file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
9) Buffer overflow (CVE-ID: CVE-2020-9880)
