Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2020-27910)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the Audio subsystem when processing media files. A remote attacker can create a specially crafted media file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
2) Out-of-bounds write (CVE-ID: CVE-2020-27916)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input within the Audio subsystem when processing media files. A remote attacker can create a specially crafted media file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
3) Out-of-bounds write (CVE-ID: CVE-2020-10017)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input within the CoreAudio subsystem when processing media files. 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.
4) Out-of-bounds read (CVE-ID: CVE-2020-27909)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the CoreAudio subsystem when processing MP4 media files. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
5) UNIX symbolic link following (CVE-ID: CVE-2020-10003)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a symlink following issue within the Crash Reporter subsystem. A local user can create a specially crafted symbolic link to a critical file on the system and overwrite it with privileges of the application.
Successful exploitation of this vulnerability may result in privilege escalation.
6) Out-of-bounds write (CVE-ID: CVE-2020-27927)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing fonts within the FontParser subsystem. A remote attacker can create a specially crafted document with a malicious font inside, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
7) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-10002)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a logic issue within the Foundation subsystem. A local user can read otherwise restricted files on the system.
8) Out-of-bounds write (CVE-ID: CVE-2020-27912)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing images within the ImageIO subsystem. A remote attacker can create a specially crafted image, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
9) Memory corruption (CVE-ID: CVE-2020-27905)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the IOAcceleratorFamily subsystem. A malicious local application can execute arbitrary code on the system with elevated privileges.
10) Security features bypass (CVE-ID: CVE-2020-9974)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists within the OS kernel that allows a local user to run a specially crafted program and determine kernel memory layout. This vulnerability can be used to bypass implemented security restrictions and leverage exploitation of other vulnerabilities.
11) Buffer overflow (CVE-ID: CVE-2020-10016)
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 application, trigger memory corruption and escalate privileges on the system.
12) Use-after-free (CVE-ID: CVE-2020-27917)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing untrusted input XML input in libxml2. A remote attacker can pass specially crafted data to the library, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
13) Integer overflow (CVE-ID: CVE-2020-27911)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow when processing XML data in libxml2. A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
14) Untrusted search path (CVE-ID: CVE-2020-10010)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper path handling of libraries within the Logging subsystem. A local user can execute arbitrary code on the system with elevated privileges.
15) Use-after-free (CVE-ID: CVE-2020-27918)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing web content within WebKit. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
