The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4928-1 advisory.

  - On some systemsdepending on the graphics settings and driversit was possible to force an out-of-bounds     read and leak memory data into the images created on the canvas element. This vulnerability affects     Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5. (CVE-2023-6204)

  - It was possible to cause the use of a MessagePort after it had already been freed, which could potentially     have led to an exploitable crash. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and     Thunderbird < 115.5. (CVE-2023-6205)

  - The black fade animation when exiting fullscreen is roughly the length of 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 < 120, Firefox ESR <     115.5.0, and Thunderbird < 115.5. (CVE-2023-6206)

  - Ownership mismanagement led to a use-after-free in ReadableByteStreams This vulnerability affects Firefox     < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5. (CVE-2023-6207)

  - When using X11, text selected by the page using the Selection API was erroneously copied into the primary     selection, a temporary storage not unlike the clipboard. *This bug only affects Firefox on X11. Other     systems are unaffected.* This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird     < 115.5. (CVE-2023-6208)

  - Relative URLs starting with three slashes were incorrectly parsed, and a path-traversal /../ part in the     path could be used to override the specified host. This could contribute to security problems in web     sites. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.
    (CVE-2023-6209)

  - Memory safety bugs present in Firefox 119, Firefox ESR 115.4, and Thunderbird 115.4. 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 < 120, Firefox ESR < 115.5.0, and     Thunderbird < 115.5. (CVE-2023-6212)

  - 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)

  - A use-after-free was identified in the `nsDNSService::Init`. This issue appears to manifest rarely during     start-up. This vulnerability affects Firefox ESR < 115.6 and Thunderbird < 115.6. (CVE-2023-6862)

  - 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)

  - 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)
