Info Packages References Vulnerabilities

In general, these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts.

  • CVE-2024-1546: Out-of-bounds memory read in networking channels (high)
    When storing and re-accessing data on a networking channel, the length of buffers may have been confused, resulting in an out-of-bounds memory read.

  • CVE-2024-1547: Alert dialog could have been spoofed on another site (high)
    Through a series of API calls and redirects, an attacker-controlled alert dialog could have been displayed on another website (with the victim website's URL shown).

  • CVE-2024-1548: Fullscreen Notification could have been hidden by select element (moderate)
    A website could have obscured the fullscreen notification by using a dropdown select input element. This could have led to user confusion and possible spoofing attacks.

  • CVE-2024-1549: Custom cursor could obscure the permission dialog (moderate)
    If a website set a large custom cursor, portions of the cursor could have overlapped with the permission dialog, potentially resulting in user confusion and unexpected granted permissions.

  • CVE-2024-1550: Mouse cursor re-positioned unexpectedly could have led to unintended permission grants (moderate)
    A malicious website could have used a combination of exiting fullscreen mode and <code>requestPointerLock</code> to cause the user's mouse to be re-positioned unexpectedly, which could have led to user confusion and inadvertently granting permissions they did not intend to grant.

  • CVE-2024-1551: Multipart HTTP Responses would accept the Set-Cookie header in response parts (moderate)
    Set-Cookie response headers were being incorrectly honored in multipart HTTP responses. If an attacker could control the Content-Type response header, as well as control part of the response body, they could inject Set-Cookie response headers that would have been honored by the browser.

  • CVE-2024-1552: Incorrect code generation on 32-bit ARM devices (low)
    Incorrect code generation could have led to unexpected numeric conversions and potential undefined behavior.*Note:* This issue only affects 32-bit ARM devices.

  • CVE-2024-1553: Memory safety bugs fixed in Firefox 123, Firefox ESR 115.8, and Thunderbird 115.8 (high)
    Memory safety bugs present in Firefox 122, Firefox ESR 115.7, and Thunderbird 115.7. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
