Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Cross-site scripting (CVE-ID: CVE-2017-2492)

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when processing data passed via a crafted web site that triggers prototype mishandling. 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.


2) Information disclosure (CVE-ID: CVE-2017-2493)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

An issue was discovered in certain Apple products. iOS before 10.3 is affected. Safari before 10.1 is affected. iCloud before 6.2 on Windows is affected. tvOS before 10.2 is affected. The issue involves the "WebKit" component. It allows remote attackers to bypass the Same Origin Policy and obtain sensitive information via a crafted elements on a web site.


3) Use-after-free (CVE-ID: CVE-2017-2463)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

An issue was discovered in certain Apple products. iOS before 10.3 is affected. Safari before 10.1 is affected. iCloud before 6.2 on Windows is affected. iTunes before 12.6 on Windows is affected. tvOS before 10.2 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.


4) Cross-site scripting (CVE-ID: CVE-2017-2475)

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when processing data passed via crafted use of frames on a web site. 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.


5) Buffer overflow (CVE-ID: CVE-2017-2476)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

An issue was discovered in certain Apple products. iOS before 10.3 is affected. Safari before 10.1 is affected. tvOS before 10.2 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.


6) Input validation error (CVE-ID: CVE-2017-2479)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

An issue was discovered in certain Apple products. iOS before 10.3 is affected. Safari before 10.1 is affected. iCloud before 6.2 on Windows is affected. iTunes before 12.6 on Windows is affected. tvOS before 10.2 is affected. The issue involves the "WebKit" component. It allows remote attackers to bypass the Same Origin Policy and obtain sensitive information via a crafted web site.
