The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2022-0850 advisory.
xmltok_impl.c in Expat (aka libexpat) before 2.4.5 lacks certain validation of encoding, such as checks for whether a UTF-8 character is valid in a certain context. (CVE-2022-25235)
Previously Thunderbird for macOS and Linux would download temporary files to a user-specific directory in <code>/tmp</code>, but this behavior was changed to download them to <code>/tmp</code> where they could be affected by other local users. This behavior was reverted to the original, user-specific directory. This bug only affects Thunderbird for macOS and Linux. Other operating systems are unaffected.
(CVE-2022-26386)
xmlparse.c in Expat (aka libexpat) before 2.4.5 allows attackers to insert namespace-separator characters into namespace URIs. (CVE-2022-25236)
In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)
An attacker could have caused a use-after-free by forcing a text reflow in an SVG object leading to a potentially exploitable crash. (CVE-2022-26381)
Mozilla: Browser window spoof using fullscreen mode (CVE-2022-26383)
If an attacker could control the contents of an iframe sandboxed with <code>allow-popups</code> but not <code>allow-scripts</code>, they were able to craft a link that, when clicked, would lead to JavaScript execution in violation of the sandbox. (CVE-2022-26384)
When installing an add-on, Thunderbird verified the signature before prompting the user; but while the user was confirming the prompt, the underlying add-on file could have been modified and Thunderbird would not have noticed. (CVE-2022-26387)
Removing an XSLT parameter during processing could have lead to an exploitable use-after-free. We have had reports of attacks in the wild abusing this flaw. (CVE-2022-26485)
An unexpected message in the WebGPU IPC framework could lead to a use-after-free and exploitable sandbox escape. We have had reports of attacks in the wild abusing this flaw. (CVE-2022-26486)
It may be possible for an attacker to craft an email message that causes Thunderbird to perform an out-of- bounds write of one byte when processing the message. (CVE-2022-0566)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
