Memory safety bugs exist that exhibit evidence of memory corruption. These issues could potentially be exploited to execute arbitrary code.

Memory safety bugs involving memory corruption may allow the execution of arbitrary code.

Memory safety bugs involving memory corruption could allow an attacker to run arbitrary code.

Memory safety bugs involving memory corruption may allow an attacker to execute arbitrary code.

A privilege escalation issue exists in the Inter-Process Communication (IPC) component. This allows for potential unauthorized access and control within the system.

A process isolation issue stems from improper handling of `javascript:` URIs, potentially allowing content to execute in the top-level document's process instead of the intended frame. This could enable a sandbox escape.

The issue is related to a use-after-free error, which could potentially allow a remote attacker to execute arbitrary code. On macOS, this could occur if a Firefox update is being applied on a very busy system, resulting in an exploitable crash.

The issue is related to memory safety bugs, which have shown evidence of memory corruption. It is presumed that with enough effort, some of these bugs could be exploited to run arbitrary code. The vulnerability is also described as a buffer overflow in memory, which could allow a remote attacker to execute arbitrary code.

The issue is related to the use of memory after it has been freed, which could allow a remote attacker to execute arbitrary code. This is due to race conditions found in reference counting code. The vulnerability affects Firefox and Firefox ESR browsers.

The issue is related to insufficient access control to certain functions, which could allow a remote attacker to load a document with higher privileges than intended. This is due to the incorrect assumption of the ordering of principal objects when loading a privileged principal.

The issue is related to the implementation of the ParseFromSafeString() function in the DOMParser interface of Mozilla Firefox. It involves the incorrect creation of a duplicate SystemPrincipal object when handling html documents. This could allow a remote attacker to bypass security restrictions.

The issue is related to insufficient protection of internal data, allowing an attacker who compromised a content process to partially escape the sandbox and read arbitrary files via clipboard-related IPC messages. This could enable a remote attacker to bypass security restrictions and gain unauthorized access to protected information by sending specially crafted IPC messages.

The issue is related to memory safety bugs, which could potentially be exploited to run arbitrary code. These bugs showed evidence of memory corruption. The vulnerability can be exploited by a remote attacker using a specially crafted website, potentially leading to memory damage and arbitrary code execution in the target system.

The issue is related to memory safety bugs, including evidence of memory corruption, which could potentially be exploited to run arbitrary code. It is also associated with a JavaScript scripting engine handler vulnerability that involves buffer copying without checking the size of input data. This could allow a remote attacker to execute arbitrary code by opening a specially crafted malicious web page.

The issue is related to memory safety bugs and buffer overflow, which can lead to memory corruption. It is presumed that with enough effort, these bugs could be exploited to run arbitrary code. The vulnerability can be exploited by a remote attacker using a specially crafted web page, potentially allowing them to execute arbitrary code on the target system.

Name of the Vulnerable Software and Affected Versions: Firefox versions prior to 88 Firefox ESR versions prior to 78.10 Thunderbird versions prior to 78.10 Description: The issue is related to errors in inherited permissions, which can be exploited by a remote attacker using a specially crafted Blob URL to elevate privileges. If a Blob URL was loaded through unusual user interaction, it could have been loaded by the System Principal and granted additional privileges that should not be granted to web content. Recommendations: For Firefox versions prior to 88, update to version 88 or later to resolve the issue. For Firefox ESR versions prior to 78.10, update to version 78.10 or later to resolve the issue. For Thunderbird versions prior to 78.10, update to version 78.10 or later to resolve the issue.

Name of the Vulnerable Software and Affected Versions: Firefox versions prior to 86 Thunderbird versions prior to 78.8 Firefox ESR versions prior to 78.8 Description: The issue is related to memory safety bugs present in certain versions of Firefox and Thunderbird, which could potentially be exploited to run arbitrary code due to evidence of memory corruption. Recommendations: For Firefox versions prior to 86, update to version 86 or later. For Thunderbird versions prior to 78.8, update to version 78.8 or later. For Firefox ESR versions prior to 78.8, update to version 78.8 or later.

The issue is caused by memory safety bugs, including evidence of memory corruption, which could potentially be exploited to run arbitrary code with enough effort. This affects various versions of Firefox, Firefox ESR, and Thunderbird.
