Arch Linux Security Advisory ASA-202009-10
Date : 2020-09-23
CVE-ID : CVE-2020-15673 CVE-2020-15674 CVE-2020-15675 CVE-2020-15676
Package : firefox
Type : multiple issues
Remote : Yes
Link : https://security.archlinux.org/AVG-1235
The package firefox before version 81.0-1 is vulnerable to multiple
issues including arbitrary code execution, content spoofing, cross-site
scripting and denial of service.
Upgrade to 81.0-1.
# pacman -Syu "firefox>=81.0-1"
The problems have been fixed upstream in version 81.0.
- CVE-2020-15673 (arbitrary code execution)
Several memory safety issues have been found in Firefox before 81.0 and
Firefox ESR 78.3. 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.
- CVE-2020-15674 (arbitrary code execution)
Several memory safety issues have been found in Firefox before 81.0.
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.
- CVE-2020-15675 (arbitrary code execution)
A use-after-free issue has been found in the WebGL implementation of
Firefox before 81.0 where, when processing surfaces, the lifetime may
outlive a persistent buffer leading to memory corruption and a
potentially exploitable crash.
- CVE-2020-15676 (cross-site scripting)
Firefox before 81.0 sometimes ran the onload handler for SVG elements
executed after pasting attacker-controlled data into a content-editable
- CVE-2020-15677 (content spoofing)
An issue has been found in Firefox before 81.0 where, by exploiting an
Open Redirect vulnerability on a website, an attacker could have
spoofed the site displayed in the download file dialog to show the
original site (the one suffering from the open redirect) rather than
the site the file was actually downloaded from.
- CVE-2020-15678 (denial of service)
A use-after-free issue has been found in Firefox before 81.0 where,
when recursing through graphical layers while scrolling, an iterator
may have become invalid, resulting in a potential use-after-free. This
occurs because the function
APZCTreeManager::ComputeClippedCompositionBounds did not follow
iterator invalidation rules.
A remote attacker might be able to cause a crash, spoof content or
execute arbitrary code.
