Description

This security bulletin contains information about 10 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2019-11709)

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

Mozilla developers and community members reported memory safety bugs present in Firefox 67 and Firefox ESR 60.7. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.


2) Input validation error (CVE-ID: CVE-2019-11711)

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

When an inner window is reused, it does not consider the use of document.domain for cross-origin protections. If pages on different subdomains ever cooperatively use document.domain, then either page can abuse this to inject script into arbitrary pages on the other subdomain, even those that did not use document.domain to relax their origin security. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.


3) Cross-site request forgery (CVE-ID: CVE-2019-11712)

The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to insufficient validation of the HTTP request origin. A remote attacker can trick the victim to visit a specially crafted web page and perform Cross-Site Request Forgery (CSRF) attacks. This vulnerability affects Firefox ESR &lt; 60.8, Firefox &lt; 68, and Thunderbird &lt; 60.


4) Use-after-free (CVE-ID: CVE-2019-11713)

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

A use-after-free vulnerability can occur in HTTP/2 when a cached HTTP/2 stream is closed while still in use, resulting in a potentially exploitable crash. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.


5) Cross-site scripting (CVE-ID: CVE-2019-11715)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Due to an error while parsing page content, it is possible for properly sanitized user input to be misinterpreted and lead to XSS hazards on web sites in certain circumstances. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.


6) Input validation error (CVE-ID: CVE-2019-11717)

The vulnerability allows a remote non-authenticated attacker to manipulate data.

A vulnerability exists where the caret ("^") character is improperly escaped constructing some URIs due to it being used as a separator, allowing for possible spoofing of origin attributes. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.


7) Out-of-bounds read (CVE-ID: CVE-2019-11719)

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

When importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger an out-of-bounds read in the Network Security Services (NSS) library. This could lead to information disclosure. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.


8) Input validation error (CVE-ID: CVE-2019-11729)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input when processing an empty or malformed p256-ECDH public keys. A remote attacker can trigger a segmentation fault and cause a denial of service condition on the target system.


9) Information disclosure (CVE-ID: CVE-2019-11730)

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

A vulnerability exists where if a user opens a locally saved HTML file, this file can use file: URIs to access other files in the same directory or sub-directories if the names are known or guessed. The Fetch API can then be used to read the contents of any files stored in these directories and they may uploaded to a server. It was demonstrated that in combination with a popular Android messaging app, if a malicious HTML attachment is sent to a user and they opened that attachment in Firefox, due to that app's predictable pattern for locally-saved file names, it is possible to read attachments the victim received from other correspondents. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.


10) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-9811)

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

As part of a winning Pwn2Own entry, a researcher demonstrated a sandbox escape by installing a malicious language pack and then opening a browser feature that used the compromised translation. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
