**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 69 Firefox ESR versions prior to 68.1 **Description** The issue is related to Content Security Policy (CSP) directives that use hash-based sources. If such a directive is defined with an empty string as input, it allows the execution of any javascript: URIs, potentially bypassing CSP permissions and enabling malicious JavaScript content to run. This could allow a remote attacker to execute arbitrary code. **Recommendations** For Firefox versions prior to 69, update to version 69 or later to resolve the issue. For Firefox ESR versions prior to 68.1, update to version 68.1 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Kaspersky Anti-Virus versions up to 2019 Kaspersky Internet Security versions up to 2019 Kaspersky Total Security versions up to 2019 Kaspersky Free Anti-Virus (affected versions not specified) Kaspersky Small Office Security (affected versions not specified) **Description** The issue is related to information disclosure in Kaspersky antivirus products. It could potentially disclose a unique Product ID by forcing the victim to visit a specially crafted webpage, such as via clicking a phishing link. This could allow a remote attacker to reveal protected information using a specially formed web page. The flaw may have allowed online trackers to identify users without using browser cookies. **Recommendations** For Kaspersky Anti-Virus versions up to 2019, update to a version later than 2019 to resolve the issue. For Kaspersky Internet Security versions up to 2019, update to a version later than 2019 to resolve the issue. For Kaspersky Total Security versions up to 2019, update to a version later than 2019 to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Firefox ESR versions prior to 52.8 Firefox versions prior to 60 PDF.js versions prior to 2.0.550 **Description** The issue is related to errors in code generation management in the PDF Viewer component of Firefox ESR and Firefox browsers. It allows a remote attacker to execute arbitrary code using a specially crafted PDF file. The PDF viewer does not sufficiently sanitize PostScript calculator functions, enabling malicious JavaScript to be injected through a crafted PDF file. This JavaScript can then be run with the permissions of the PDF viewer by its worker. **Recommendations** For Firefox ESR versions prior to 52.8, update to version 52.8 or later. For Firefox versions prior to 60, update to version 60 or later. For PDF.js versions prior to 2.0.550, update to version 2.0.550 or later.

**Name of the Vulnerable Software and Affected Versions** Thunderbird versions prior to 52.8 Thunderbird ESR versions prior to 52.8 Firefox versions prior to 60 Firefox ESR versions prior to 52.8 **Description** The issue is related to the manipulation of the `baseURI` property of the theme element, allowing sites to bypass security checks on permissions to install lightweight themes. This could enable a malicious site to install a theme without user interaction, potentially containing offensive or embarrassing images. The vulnerability is associated with errors in processing permissions. **Recommendations** For Thunderbird versions prior to 52.8, update to version 52.8 or later. For Thunderbird ESR versions prior to 52.8, update to version 52.8 or later. For Firefox versions prior to 60, update to version 60 or later. For Firefox ESR versions prior to 52.8, update to version 52.8 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox ESR versions prior to 52.8 Firefox versions prior to 60 **Description** The issue allows a malicious site to bypass same-origin protections for the PDF viewer, potentially intercepting messages meant for the viewer. This could enable the site to retrieve PDF files restricted to viewing by an authenticated user on a third-party website. The vulnerability is also described as being due to insufficient input validation in the Capture Handler component of Firefox ESR and Firefox browsers, which could allow a remote attacker to elevate their privileges. **Recommendations** For Firefox ESR versions prior to 52.8, update to version 52.8 or later. For Firefox versions prior to 60, update to version 60 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 60 **Description** The issue is related to the web console and JavaScript debugger not properly sanitizing output, which can lead to displaying internal chrome pages as active hyperlinks. This could allow malicious sites to trick users into clicking on "javascript:" links, potentially leading to unauthorized access to protected information. **Recommendations** For versions prior to 60, update to version 60 or later to resolve the issue. As a temporary workaround, consider restricting access to the web console and JavaScript debugger to minimize the risk of exploitation. Avoid clicking on suspicious links, especially those starting with "chrome:" or "javascript:".

**Name of the Vulnerable Software and Affected Versions** Firefox ESR versions prior to 45.6 Firefox versions prior to 50.1 **Description** The Pocket toolbar button in Firefox does not verify the origin of incoming events, allowing content from other origins to fire events and inject content and commands into the Pocket context. This issue does not affect users with e10s enabled. **Recommendations** For Firefox ESR versions prior to 45.6, update to version 45.6 or later to resolve the issue. For Firefox versions prior to 50.1, update to version 50.1 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Firefox ESR versions prior to 45.6 Firefox versions prior to 50.1 **Description** The issue allows HTML tags received from the Pocket server to be processed without sanitization, enabling any JavaScript code to be executed in the "about:pocket-saved" page. This gives the code access to Pocket's messaging API through HTML injection. **Recommendations** For Firefox ESR versions prior to 45.6, update to version 45.6 or later. For Firefox versions prior to 50.1, update to version 50.1 or later.

**Name of the Vulnerable Software and Affected Versions** Bugzilla versions 2.16rc1 through 4.4.11 Bugzilla versions 4.5.1 through 5.0.2 **Description** A cross-site scripting (XSS) issue exists in the dependency graphs of Bugzilla, allowing remote attackers to inject arbitrary web script or HTML. This enables attackers to execute malicious scripts on the victim's browser, potentially leading to unauthorized actions or data theft. **Recommendations** For Bugzilla versions 2.16rc1 through 4.4.11, update to a version outside of this range to resolve the issue. For Bugzilla versions 4.5.1 through 5.0.2, update to a version outside of this range to resolve the issue. As a temporary workaround, consider restricting access to the dependency graphs feature until a patch is available.
