Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 38 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2023-983329cf45 advisory.

- Multiple NSS NIST curves were susceptible to a side-channel attack known as Minerva. This attack could potentially allow an attacker to recover the private key. This vulnerability affects Firefox < 121.
(CVE-2023-6135)

- The WebGL `DrawElementsInstanced` method was susceptible to a heap buffer overflow when used on systems with the Mesa VM driver. This issue could allow an attacker to perform remote code execution and sandbox escape. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.
(CVE-2023-6856)

- When resolving a symlink, a race may occur where the buffer passed to `readlink` may actually be smaller than necessary. *This bug only affects Firefox on Unix-based operating systems (Android, Linux, MacOS).
Windows is unaffected.* This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121. (CVE-2023-6857)

- Firefox was susceptible to a heap buffer overflow in `nsTextFragment` due to insufficient OOM handling.
This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121. (CVE-2023-6858)

- A use-after-free condition affected TLS socket creation when under memory pressure. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121. (CVE-2023-6859)

- The `VideoBridge` allowed any content process to use textures produced by remote decoders. This could be abused to escape the sandbox. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121. (CVE-2023-6860)

- The `nsWindow::PickerOpen(void)` method was susceptible to a heap buffer overflow when running in headless mode. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.
(CVE-2023-6861)

- The `ShutdownObserver()` was susceptible to potentially undefined behavior due to its reliance on a dynamic type that lacked a virtual destructor. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121. (CVE-2023-6863)

- Memory safety bugs present in Firefox 120, Firefox ESR 115.5, and Thunderbird 115.5. 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. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121. (CVE-2023-6864)

- `EncryptingOutputStream` was susceptible to exposing uninitialized data. This issue could only be abused in order to write data to a local disk which may have implications for private browsing mode. This vulnerability affects Firefox ESR < 115.6 and Firefox < 121. (CVE-2023-6865)

- TypedArrays can be fallible and lacked proper exception handling. This could lead to abuse in other APIs which expect TypedArrays to always succeed. This vulnerability affects Firefox < 121. (CVE-2023-6866)

- The timing of a button click causing a popup to disappear was approximately the same length as the anti- clickjacking delay on permission prompts. It was possible to use this fact to surprise users by luring them to click where the permission grant button would be about to appear. This vulnerability affects Firefox ESR < 115.6 and Firefox < 121. (CVE-2023-6867)

- In some instances, the user-agent would allow push requests which lacked a valid VAPID even though the push manager subscription defined one. This could allow empty messages to be sent from unauthorized parties. *This bug only affects Firefox on Android.* This vulnerability affects Firefox < 121.
(CVE-2023-6868)

- A `<dialog>` element could have been manipulated to paint content outside of a sandboxed iframe. This could allow untrusted content to display under the guise of trusted content. This vulnerability affects Firefox < 121. (CVE-2023-6869)

- Applications which spawn a Toast notification in a background thread may have obscured fullscreen notifications displayed by Firefox. *This issue only affects Android versions of Firefox and Firefox Focus.* This vulnerability affects Firefox < 121. (CVE-2023-6870)

- Under certain conditions, Firefox did not display a warning when a user attempted to navigate to a new protocol handler. This vulnerability affects Firefox < 121. (CVE-2023-6871)

- Browser tab titles were being leaked by GNOME to system logs. This could potentially expose the browsing habits of users running in a private tab. This vulnerability affects Firefox < 121. (CVE-2023-6872)

- Memory safety bugs present in Firefox 120. 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. This vulnerability affects Firefox < 121. (CVE-2023-6873)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected firefox and / or nss packages.
