Details
Niklas Baumstark discovered that a compromised web child process of Firefox
could disable web security opening restrictions, leading to a new child
process being spawned within the file:// context. An attacker could
potentially exploits this to obtain sensitive information. (CVE-2023-23597)
Tom Schuster discovered that Firefox was not performing a validation check
on GTK drag data. An attacker could potentially exploits this to obtain
sensitive information. (CVE-2023-23598)
Vadim discovered that Firefox was not properly sanitizing a curl command
output when copying a network request from the developer tools panel. An
attacker could potentially exploits this to hide and execute arbitrary
commands. (CVE-2023-23599)
Luan Herrera discovered that Firefox was not stopping navigation when
dragging a URL from a cross-origin iframe into the same tab. An attacker
potentially exploits this to spoof the user. (CVE-2023-23601)
Dave Vandyke discovered that Firefox did not properly implement CSP policy
when creating a WebSocket in a WebWorker. An attacker who was able to
inject markup into a page otherwise protected by a Content Security Policy
may have been able to inject an executable script. (CVE-2023-23602)
Dan Veditz discovered that Firefox did not properly implement CSP policy
on regular expression when using console.log. An attacker potentially
exploits this to exfiltrate data from the browser. (CVE-2023-23603)
Nika Layzell discovered that Firefox was not performing a validation check
when parsing a non-system html document via DOMParser::ParseFromSafeString.
An attacker potentially exploits this to bypass web security checks.
(CVE-2023-23604)
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-2023-23605,
CVE-2023-23606)
Update instructions
