Name of the Vulnerable Software and Affected Versions: Firefox versions prior to 142 Firefox ESR versions prior to 140.2 Thunderbird versions prior to 142 Thunderbird ESR versions prior to 140.2 Description: Memory safety bugs are present in the software, with some showing evidence of memory corruption. It is presumed that, with sufficient effort, some of these bugs could be exploited to run arbitrary code. Recommendations: Update Firefox to version 142 or later. Update Firefox ESR to version 140.2 or later. Update Thunderbird to version 142 or later. Update Thunderbird ESR to version 140.2 or later.

The issue is related to memory safety bugs, which have shown evidence of memory corruption. It is presumed that with sufficient effort, some of 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.

The issue is related to incorrect clearing or release of resources, potentially allowing a remote attacker to impact the confidentiality, availability, and integrity of protected information. The behavior for out-of-memory conditions was changed to crash instead of attempting to continue, in order to harden against exploitation.

The issue is related to memory safety bugs that could potentially be exploited to run arbitrary code, with evidence of memory corruption found in some cases. The vulnerability may allow a remote attacker to impact the integrity of protected information by exploiting errors in state management due to an excessive number of cookies in `document.cookie`. Additionally, the vulnerability in the Mozilla Thunderbird email client is related to a boundary error when processing HTML content, which could allow an attacker to trick a victim into opening a specially crafted web page, causing memory damage and potentially executing arbitrary code.

The issue is related to memory safety bugs present in Firefox, which showed evidence of memory corruption. It is presumed that with enough effort, some of these bugs could have been exploited to run arbitrary code. The vulnerability can be exploited by a remote attacker using a specially crafted malicious web page, potentially allowing them to execute arbitrary code.

The issue is related to a buffer data boundary operation overflow. It may allow a remote attacker to execute arbitrary code. Memory safety bugs were reported, showing evidence of memory corruption, which could potentially be exploited.

The issue is related to memory safety bugs, including evidence of memory corruption, which could potentially be exploited to run arbitrary code. This is due to a buffer overflow in memory, allowing a remote attacker to execute arbitrary code.
