Mozilla developers Bryce Seager van Dyk and the Mozilla Fuzzing Team reported potential vulnerabilities present in Firefox 101. 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 < 102.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3396-1 advisory.

 - If an object prototype was corrupted by an attacker, they would have been able to set undesired attributes on a JavaScript object, leading to privileged code execution. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-2200)

 - Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 102. 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 < 102.1, Firefox < 103, and Thunderbird < 102.1. (CVE-2022-2505)

 - An iframe that was not permitted to run scripts could do so if the user clicked on a <code>javascript:</code> link. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-34468)

 - When a TLS Certificate error occurs on a domain protected by the HSTS header, the browser should not allow the user to bypass the certificate error. On Firefox for Android, the user was presented with the option to bypass the error; this could only have been done by the user explicitly. *This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 102.
 (CVE-2022-34469)

 - Session history navigations may have led to a use-after-free and potentially exploitable crash. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11.
 (CVE-2022-34470)

 - When downloading an update for an addon, the downloaded addon update's version was not verified to match the version selected from the manifest. If the manifest had been tampered with on the server, an attacker could trick the browser into downgrading the addon to a prior version. This vulnerability affects Firefox < 102. (CVE-2022-34471)

 - If there was a PAC URL set and the server that hosts the PAC was not reachable, OCSP requests would have been blocked, resulting in incorrect error pages being shown. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-34472)

 - The HTML Sanitizer should have sanitized the <code>href</code> attribute of SVG <code><use></code> tags; however it incorrectly did not sanitize <code>xlink:href</code> attributes. This vulnerability affects Firefox < 102. (CVE-2022-34473)

 - Even when an iframe was sandboxed with <code>allow-top-navigation-by-user-activation</code>, if it received a redirect header to an external protocol the browser would process the redirect and prompt the user as appropriate. This vulnerability affects Firefox < 102. (CVE-2022-34474)

 - SVG <code><use></code> tags that referenced a same-origin document could have resulted in script execution if attacker input was sanitized via the HTML Sanitizer API. This would have required the attacker to reference a same-origin JavaScript file containing the script to be executed. This vulnerability affects Firefox < 102. (CVE-2022-34475)

 - ASN.1 parsing of an indefinite SEQUENCE inside an indefinite GROUP could have resulted in the parser accepting malformed ASN.1. This vulnerability affects Firefox < 102. (CVE-2022-34476)

 - The MediaError message property should be consistent to avoid leaking information about cross-origin resources; however for a same-site cross-origin resource, the message could have leaked information enabling XS-Leaks attacks. This vulnerability affects Firefox < 102. (CVE-2022-34477)

 - The <code>ms-msdt</code>, <code>search</code>, and <code>search-ms</code> protocols deliver content to Microsoft applications, bypassing the browser, when a user accepts a prompt. These applications have had known vulnerabilities, exploited in the wild (although we know of none exploited through Thunderbird), so in this release Thunderbird has blocked these protocols from prompting the user to open them. *This bug only affects Thunderbird on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-34478)

 - A malicious website that could create a popup could have resized the popup to overlay the address bar with its own content, resulting in potential user confusion or spoofing attacks. *This bug only affects Thunderbird for Linux. Other operating systems are unaffected.*. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-34479)

 - Within the <code>lg_init()</code> function, if several allocations succeed but then one fails, an uninitialized pointer would have been freed despite never being allocated. This vulnerability affects Firefox < 102. (CVE-2022-34480)

 - In the <code>nsTArray_Impl::ReplaceElementsAt()</code> function, an integer overflow could have occurred when the number of elements to replace was too large for the container. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-34481)

 - An attacker who could have convinced a user to drag and drop an image to a filesystem could have manipulated the resulting filename to contain an executable extension, and by extension potentially tricked the user into executing malicious code. While very similar, this is a separate issue from CVE-2022-34483. This vulnerability affects Firefox < 102. (CVE-2022-34482)

(CVE-2022-34485)

 - When opening a Windows shortcut from the local filesystem, an attacker could supply a remote path that would lead to unexpected network requests from the operating system. This bug only affects Firefox for Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 102.1, Firefox < 103, and Thunderbird < 102.1. (CVE-2022-36314)

 - When visiting directory listings for `chrome://` URLs as source text, some parameters were reflected. This vulnerability affects Firefox ESR < 102.1, Firefox ESR < 91.12, Firefox < 103, Thunderbird < 102.1, and Thunderbird < 91.12. (CVE-2022-36318)

 - When combining CSS properties for overflow and transform, the mouse cursor could interact with different coordinates than displayed. This vulnerability affects Firefox ESR < 102.1, Firefox ESR < 91.12, Firefox < 103, Thunderbird < 102.1, and Thunderbird < 91.12. (CVE-2022-36319)

 - An attacker could have abused XSLT error handling to associate attacker-controlled content with another origin which was displayed in the address bar. This could have been used to fool the user into submitting data intended for the spoofed origin. This vulnerability affects Thunderbird < 102.2, Thunderbird < 91.13, Firefox ESR < 91.13, Firefox ESR < 102.2, and Firefox < 104. (CVE-2022-38472)

 - A cross-origin iframe referencing an XSLT document would inherit the parent domain's permissions (such as microphone or camera access). This vulnerability affects Thunderbird < 102.2, Thunderbird < 91.13, Firefox ESR < 91.13, Firefox ESR < 102.2, and Firefox < 104. (CVE-2022-38473)

 - A data race could occur in the <code>PK11_ChangePW</code> function, potentially leading to a use-after- free vulnerability. In Firefox, this lock protected the data when a user changed their master password.
 This vulnerability affects Firefox ESR < 102.2 and Thunderbird < 102.2. (CVE-2022-38476)

 - Mozilla developer Nika Layzell and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 103 and Firefox ESR 102.1.

 (CVE-2022-38478)

 - When injecting an HTML base element, some requests would ignore the CSP's base-uri settings and accept the injected element's base instead. This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105. (CVE-2022-40956)

 - Inconsistent data in instruction and data cache when creating wasm code could lead to a potentially exploitable crash. *This bug only affects Firefox on ARM64 platforms.*. This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105. (CVE-2022-40957)

 - By injecting a cookie with certain special characters, an attacker on a shared subdomain which is not a secure context could set and thus overwrite cookies from a secure context, leading to session fixation and other attacks. This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105.
 (CVE-2022-40958)

 - During iframe navigation, certain pages did not have their FeaturePolicy fully initialized leading to a bypass that leaked device permissions into untrusted subdocuments. This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105. (CVE-2022-40959)

 - Concurrent use of the URL parser with non-UTF-8 data was not thread-safe. This could lead to a use-after- free causing a potentially exploitable crash. This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105. (CVE-2022-40960)

The remote host is affected by the vulnerability described in GLSA-202208-08 (Mozilla Firefox: Multiple Vulnerabilities)

 - Use after free in Codecs in Google Chrome prior to 101.0.4951.41 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2022-1919)

 - regex is an implementation of regular expressions for the Rust language. The regex crate features built-in mitigations to prevent denial of service attacks caused by untrusted regexes, or untrusted input matched by trusted regexes. Those (tunable) mitigations already provide sane defaults to prevent attacks. This guarantee is documented and it's considered part of the crate's API. Unfortunately a bug was discovered in the mitigations designed to prevent untrusted regexes to take an arbitrary amount of time during parsing, and it's possible to craft regexes that bypass such mitigations. This makes it possible to perform denial of service attacks by sending specially crafted regexes to services accepting user-controlled, untrusted regexes. All versions of the regex crate before or equal to 1.5.4 are affected by this issue. The fix is include starting from regex 1.5.5. All users accepting user-controlled regexes are recommended to upgrade immediately to the latest version of the regex crate. Unfortunately there is no fixed set of problematic regexes, as there are practically infinite regexes that could be crafted to exploit this vulnerability.
 Because of this, it us not recommend to deny known problematic regexes. (CVE-2022-24713)

 - 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)

 - In unusual circumstances, an individual thread may outlive the thread's manager during shutdown. This could have led to a use-after-free causing a potentially exploitable crash. (CVE-2022-26385)

 - 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)

 - SVG's <code><use></code> element could have been used to load unexpected content that could have executed script in certain circumstances. While the specification seems to allow this, other browsers do not, and web developers relied on this property for script security so gecko's implementation was aligned with theirs. (CVE-2022-28284)

 - When generating the assembly code for <code>MLoadTypedArrayElementHole</code>, an incorrect AliasSet was used. In conjunction with another vulnerability this could have been used for an out of bounds memory read. (CVE-2022-28285)

 - The <code>ms-msdt</code>, <code>search</code>, and <code>search-ms</code> protocols deliver content to Microsoft applications, bypassing the browser, when a user accepts a prompt. These applications have had known vulnerabilities, exploited in the wild (although we know of none exploited through Thunderbird), so in this release Thunderbird has blocked these protocols from prompting the user to open them. This bug only affects Thunderbird on Windows. Other operating systems are unaffected. (CVE-2022-34478)
