[ASA-202104-3] firefox: multiple issues
Arch Linux Security Advisory ASA-202104-3 ========================================= Severity: High Date : 2021-04-29 CVE-ID : CVE-2021-23994 CVE-2021-23995 CVE-2021-23996 CVE-2021-23997 CVE-2021-23998 CVE-2021-23999 CVE-2021-24000 CVE-2021-24001 CVE-2021-24002 CVE-2021-29946 CVE-2021-29947 Package : firefox Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1834 Summary ======= The package firefox before version 88.0-1 is vulnerable to multiple issues including arbitrary code execution, content spoofing, arbitrary command execution, sandbox escape and access restriction bypass. Resolution ========== Upgrade to 88.0-1. # pacman -Syu "firefox>=88.0-1" The problems have been fixed upstream in version 88.0. Workaround ========== None. Description =========== - CVE-2021-23994 (arbitrary code execution) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. A WebGL framebuffer was not initialized early enough, resulting in memory corruption and an out of bounds write. - CVE-2021-23995 (arbitrary code execution) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. When Responsive Design Mode was enabled, it used references to objects that were previously freed. Mozilla presumes that with enough effort this could have been exploited to run arbitrary code. - CVE-2021-23996 (content spoofing) A security issue has been found in Firefox before version 88. By utilizing 3D CSS in conjunction with Javascript, content could have been rendered outside the webpage's viewport, resulting in a spoofing attack that could have been used for phishing or other attacks on a user. - CVE-2021-23997 (arbitrary code execution) A security issue has been found in Firefox before version 88. Due to unexpected data type conversions, a use-after-free could have occurred when interacting with the font cache. Mozilla presumes that with enough effort this could have been exploited to run arbitrary code. - CVE-2021-23998 (content spoofing) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. Through complicated navigations with new windows, an HTTP page could have inherited a secure lock icon from an HTTPS page. - CVE-2021-23999 (sandbox escape) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. If a Blob URL was loaded through some unusual user interaction, it could have been loaded by the System Principal and granted additional privileges that should not be granted to web content. - CVE-2021-24000 (content spoofing) A security issue has been found in Firefox before version 88. A race condition with requestPointerLock() and setTimeout() could have resulted in a user interacting with one tab when they believed they were on a separate tab. In conjunction with certain elements (such as <input type="file">) this could have led to an attack where a user was confused about the origin of the webpage and potentially disclosed information they did not intend to. - CVE-2021-24001 (sandbox escape) A security issue has been found in Firefox before version 88. A compromised content process could have performed session history manipulations it should not have been able to due to testing infrastructure that was not restricted to testing-only configurations. - CVE-2021-24002 (arbitrary command execution) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. When a user clicked on an FTP URL containing encoded newline characters (%0A and %0D), the newlines would have been interpreted as such and allowed arbitrary commands to be sent to the FTP server. - CVE-2021-29946 (access restriction bypass) A security issue has been found in Firefox before version 88 and Thunderbird before version 78.10. Ports that were written as an integer overflow above the bounds of a 16-bit integer could have bypassed port blocking restrictions when used in the Alt-Svc header. - CVE-2021-29947 (arbitrary code execution) A security issue has been found in Firefox before version 88. Mozilla developers and community members reported memory safety bugs present in Firefox 87. Some of these bugs showed evidence of memory corruption and Mozilla presumes that with enough effort some of these could have been exploited to run arbitrary code. Impact ====== An attacker is able to execute arbitrary code, spoof context, escape the sandbox, and bypass port blocking restrictions through various means.
