Description

This security bulletin contains information about 17 secuirty vulnerabilities.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-3917)

The vulnerability allows a remote attacker to gain access to sensitive information on the system.

The vulnerability exists due to a security restriction bypass. A remote attacker can trick a victim to install a malicious application, cause the application to be able to use an SSH client provided by private frameworks and gain access to sensitive information on the target system.


2) Buffer overflow (CVE-ID: CVE-2020-3911)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in libxml2. A remote attacker can use a specially crafted application, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


3) Type Confusion (CVE-ID: CVE-2020-3897)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a type confusion error within the object transition cache. A remote attacker can trick a victim to visit a malicisou page or open a specially crafted file, trigger a type confusion error and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


4) Type Confusion (CVE-ID: CVE-2020-3901)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a type confusion error when processing maliciously crafted web content. A remote attacker can trick a victim to open a specially crafted file or visit a malicious page, trigger a type confusion error and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


5) Buffer overflow (CVE-ID: CVE-2020-3900)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing maliciously crafted web content. A remote attacker can trick a victim to open a specially crafted file or visit a malicious page, 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-2020-3895)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing maliciously crafted web content. A remote attacker can trick a victim to open a specially crafted file or visit a malicious page, 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-2020-3910)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in libxml2. A remote attacker can use a specially crafted application, 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-2020-3909)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in libxml2. A remote attacker can use a specially crafted application, 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) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-3883)

The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to improper permission checks in AppleMobileFileIntegrity. A remote attacker can trick a victim to install a malicious application and cause the application to be able to use arbitrary entitlements.


10) Buffer overflow (CVE-ID: CVE-2020-9785)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error. A remote attacker can use a specially crafted application, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


11) Out-of-bounds read (CVE-ID: CVE-2020-3914)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition. A remote attacker can use a specially crafted application, trigger out-of-bounds read error and read contents of memory on the system.


12) Buffer overflow (CVE-ID: CVE-2020-3919)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error. A remote attacker can use a specially crafted application, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


13) Use-after-free (CVE-ID: CVE-2020-9768)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error. A remote attacker can use a specially crafted application and execute arbitrary code on the target system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


14) Improper access control (CVE-ID: CVE-2020-3916)

The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions. A remote attacker can set an alternate app icon and disclose a photo without needing permission to access photos.


15) Information disclosure (CVE-ID: CVE-2020-9773)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to improper handling of icon caches. A remote attacker can trick a victim to install a malicious application and identify what other applications a user has installed.


16) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-3913)

The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to improper permissions check. A remote attacker can trick a victim to install a malicious application and use the application and gain elevated privileges on the target system.


17) Business Logic Errors (CVE-ID: CVE-2020-3891)

The vulnerability allows a local attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to logical errors. A an attacker with physical access to a locked iOS device may be able to respond to messages even when replies are disabled.
