Oracle Linux 9 : firefox (ELSA-2023-1786)

high Nessus Plugin ID 174385


The remote Oracle Linux host is missing one or more security updates.


The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2023-1786 advisory.

- Unexpected data returned from the Safe Browsing API could have led to memory corruption and a potentially exploitable crash. (CVE-2023-1945)

- When handling the filename directive in the Content-Disposition header, the filename would be truncated if the filename contained a NULL character. This could have led to reflected file download attacks potentially tricking users to install malware. (CVE-2023-29539)

- Thunderbird did not properly handle downloads of files ending in <code>.desktop</code>, which can be interpreted to run attacker-controlled commands. This bug only affects Thunderbird for Linux on certain Distributions. Other operating systems are unaffected, and Mozilla is unable to enumerate all affected Linux Distributions. (CVE-2023-29541)

- A website could have obscured the fullscreen notification by using a combination of <code></code>, fullscreen requests, <code></code> assignments, and <code>setInterval</code> calls. This could have led to user confusion and possible spoofing attacks.

- Mozilla developers Andrew Osmond, Sebastian Hengst, Andrew McCreight, and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 102.9. 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. (CVE-2023-29550)

- An attacker could cause the memory manager to incorrectly free a pointer that addresses attacker- controlled memory, resulting in an assertion, memory corruption, or a potentially exploitable crash.

- Following a Garbage Collector compaction, weak maps may have been accessed before they were correctly traced. This resulted in memory corruption and a potentially exploitable crash. (CVE-2023-29535)

- A wrong lowering instruction in the ARM64 Ion compiler resulted in a wrong optimization result.

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


Update the affected firefox and / or firefox-x11 packages.
