Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Business Logic Errors (CVE-ID: CVE-2020-9784)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to logical errors. A remote attacker can trick a victim to open a specially crafted file or visit a malicious page and use a malicious iframe to use another website’s download settings.
2) 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.
3) Business Logic Errors (CVE-ID: CVE-2020-3887)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to logical errors. A remote attacker can trick a victim to open a specially crafted file or visit a malicious page and cause a download's origin may be incorrectly associated.
4) 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.
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) Race condition (CVE-ID: CVE-2020-3894)
The vulnerability allows a remote attacker to gain access to sensitive information on the system.
The vulnerability exists due to a race condition. A remote atacker can trick a victim to open a specially crafted file or visit a malicioous page, exploit the race and gain unauthorized access to sensitive information on the target system.
7) 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.
8) Use-after-free (CVE-ID: CVE-2020-9783)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free 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 and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
9) Buffer overflow (CVE-ID: CVE-2020-3899)
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 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.
10) Cross-site scripting (CVE-ID: CVE-2020-3902)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
