2) Buffer overflow (CVE-ID: CVE-2024-6602)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in NSS. A remote attacker can create a specially crafted web page, 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.
3) Buffer overflow (CVE-ID: CVE-2024-6603)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

4) Buffer overflow (CVE-ID: CVE-2024-6604)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing HTML content. A remote attacker can create a specially crafted website, 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.
5) Security restrictions bypass (CVE-ID: CVE-2017-12363)
The vulnerability allows a remote attacker to obtain bypass security restrictions on the target system.

7) Improper input validation (CVE-ID: CVE-2017-12297)
The vulnerability allows a remote authenticated attacker to initiate connections to arbitrary hosts.
The vulnerability exists due to insufficient access control for HTTP traffic directed to the Cisco WebEx Meeting Center. A remote attacker can send a malicious URL to the Cisco WebEx Meeting Center and connect to arbitrary hosts.
8) Cross-site scripting (CVE-ID: CVE-2017-12366)
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.
