firefox security update
Mozilla Firefox is a standalone web browser, designed for standards compliance and performance. Its functionality can be enhanced via a plethora of extensions.
Security Fix(es):
When loading a script with Subresource Integrity, attackers with an injection capability could trigger the reuse of previously cached entries with incorrect, different integrity metadata. This vulnerability affects Firefox < 103.(CVE-2022-36315)
When using the Performance API, an attacker was able to notice subtle differences between PerformanceEntries and thus learn whether the target URL had been subject to a redirect. This vulnerability affects Firefox < 103.(CVE-2022-36316)
An attacker could have written a value to the first element in a zero-length JavaScript array. Although the array was zero-length, the value was not written to an invalid memory address. This vulnerability affects Firefox < 104.(CVE-2022-38475)
Service Workers did not detect Private Browsing Mode correctly in all cases, which could have led to Service Workers being written to disk for websites visited in Private Browsing Mode. This would not have persisted them in a state where they would run again, but it would have leaked Private Browsing Mode details to disk. This vulnerability affects Firefox < 107.(CVE-2022-45417)
If the user added a security exception for an invalid TLS certificate, opened an ongoing TLS connection with a server that used that certificate, and then deleted the exception, Firefox would have kept the connection alive, making it seem like the certificate was still trusted. This vulnerability affects Firefox < 107.(CVE-2022-45419)
Mozilla developers and community members Lukas Bernhard, Gabriele Svelto, Randell Jesup, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 107. 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 < 108.(CVE-2022-46879)
Mozilla developers Gabriele Svelto, Yulia Startsev, Andrew McCreight and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 106. 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.<br />Note: This advisory was added on December 13th, 2022 after discovering it was inadvertently left out of the original advisory. The fix was included in the original release of Firefox 107. This vulnerability affects Firefox < 107.(CVE-2022-46883)
Due to URL previews in the network panel of developer tools improperly storing URLs, query parameters could potentially be used to overwrite global objects in privileged code. This vulnerability affects Firefox < 110.(CVE-2023-25731)
The return value from gfx::SourceSurfaceSkia::Map() wasn't being verified which could have potentially lead to a null pointer dereference. This vulnerability affects Firefox < 110.(CVE-2023-25733)
An invalid downcast from nsHTMLDocument to nsIContent could have lead to undefined behavior. This vulnerability affects Firefox < 110.(CVE-2023-25736)
Under certain circumstances, a ServiceWorker's offline cache may have leaked to the file system when using private browsing mode. This vulnerability affects Firefox < 111.(CVE-2023-25750)
When following a redirect to a publicly accessible web extension file, the URL may have been translated to the actual local path, leaking potentially sensitive information. This vulnerability affects Firefox < 111.(CVE-2023-28160)
Memory safety bugs present in Firefox 110. 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 < 111.(CVE-2023-28177)

firefox vulnerabilities
Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. (CVE-2024-2609, CVE-2024-2611, CVE-2024-2614, CVE-2024-2615)
Hubert Kario discovered that Firefox had a timing side-channel when performing RSA decryption. A remote attacker could possibly use this issue to recover sensitive information. (CVE-2023-5388)
It was discovered that Firefox did not properly handle WASM register values in some circumstances. An attacker could potentially exploit this issue to cause a denial of service. (CVE-2024-2606)
Gary Kwong discovered that Firefox incorrectly updated return registers for JIT code on Armv7-A systems. An attacker could potentially exploit this issue to execute arbitrary code. (CVE-2024-2607)
Ronald Crane discovered that Firefox did not properly manage memory during character encoding. An attacker could potentially exploit this issue to cause a denial of service. (CVE-2024-2608)
Georg Felber and Marco Squarcina discovered that Firefox incorrectly handled html and body tags. An attacker who was able to inject markup into a page otherwise protected by a Content Security Policy may have been able obtain sensitive information. (CVE-2024-2610)
Ronald Crane discovered a use-after-free in Firefox when handling code in SafeRefPtr. An attacker could potentially exploit this issue to cause a denial of service, or execute arbitrary code. (CVE-2024-2612)
