CVE-2020-26973 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 8.8 High
Certain input to the CSS Sanitizer confused it, resulting in incorrect components being removed. This could have been used as a sanitizer bypass. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
CVE-2020-26971 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 8.8 High
Certain blit values provided by the user were not properly constrained leading to a heap buffer overflow on some video drivers. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
CVE-2020-26970 2 Mozilla, Redhat 4 Thunderbird, Enterprise Linux, Rhel E4s and 1 more 2024-11-21 8.8 High
When reading SMTP server status codes, Thunderbird writes an integer value to a position on the stack that is intended to contain just one byte. Depending on processor architecture and stack layout, this leads to stack corruption that may be exploitable. This vulnerability affects Thunderbird < 78.5.1.
CVE-2020-26968 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 8.8 High
Mozilla developers reported memory safety bugs present in Firefox 82 and Firefox ESR 78.4. 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 < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26965 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 6.5 Medium
Some websites have a feature "Show Password" where clicking a button will change a password field into a textbook field, revealing the typed password. If, when using a software keyboard that remembers user input, a user typed their password and used that feature, the type of the password field was changed, resulting in a keyboard layout change and the possibility for the software keyboard to remember the typed password. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26961 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 6.5 Medium
When DNS over HTTPS is in use, it intentionally filters RFC1918 and related IP ranges from the responses as these do not make sense coming from a DoH resolver. However when an IPv4 address was mapped through IPv6, these addresses were erroneously let through, leading to a potential DNS Rebinding attack. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26960 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 8.8 High
If the Compact() method was called on an nsTArray, the array could have been reallocated without updating other pointers, leading to a potential use-after-free and exploitable crash. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26959 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 8.8 High
During browser shutdown, reference decrementing could have occured on a previously freed object, resulting in a use-after-free, memory corruption, and a potentially exploitable crash. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26958 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 6.1 Medium
Firefox did not block execution of scripts with incorrect MIME types when the response was intercepted and cached through a ServiceWorker. This could lead to a cross-site script inclusion vulnerability, or a Content Security Policy bypass. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26956 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 6.1 Medium
In some cases, removing HTML elements during sanitization would keep existing SVG event handlers and therefore lead to XSS. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26953 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 4.3 Medium
It was possible to cause the browser to enter fullscreen mode without displaying the security UI; thus making it possible to attempt a phishing attack or otherwise confuse the user. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26951 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 6.1 Medium
A parsing and event loading mismatch in Firefox's SVG code could have allowed load events to fire, even after sanitization. An attacker already capable of exploiting an XSS vulnerability in privileged internal pages could have used this attack to bypass our built-in sanitizer. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26950 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 8.8 High
In certain circumstances, the MCallGetProperty opcode can be emitted with unmet assumptions resulting in an exploitable use-after-free condition. This vulnerability affects Firefox < 82.0.3, Firefox ESR < 78.4.1, and Thunderbird < 78.4.2.
CVE-2020-26541 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more 2024-11-21 6.5 Medium
The Linux kernel through 5.8.13 does not properly enforce the Secure Boot Forbidden Signature Database (aka dbx) protection mechanism. This affects certs/blacklist.c and certs/system_keyring.c.
CVE-2020-26154 5 Debian, Fedoraproject, Libproxy Project and 2 more 6 Debian Linux, Fedora, Libproxy and 3 more 2024-11-21 9.8 Critical
url.cpp in libproxy through 0.4.15 is prone to a buffer overflow when PAC is enabled, as demonstrated by a large PAC file that is delivered without a Content-length header.
CVE-2020-26116 8 Canonical, Debian, Fedoraproject and 5 more 12 Ubuntu Linux, Debian Linux, Fedora and 9 more 2024-11-21 7.2 High
http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5 allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of HTTPConnection.request.
CVE-2020-25723 3 Debian, Qemu, Redhat 5 Debian Linux, Qemu, Advanced Virtualization and 2 more 2024-11-21 3.2 Low
A reachable assertion issue was found in the USB EHCI emulation code of QEMU. It could occur while processing USB requests due to missing handling of DMA memory map failure. A malicious privileged user within the guest may abuse this flaw to send bogus USB requests and crash the QEMU process on the host, resulting in a denial of service.
CVE-2020-25719 5 Canonical, Debian, Fedoraproject and 2 more 18 Ubuntu Linux, Debian Linux, Fedora and 15 more 2024-11-21 7.2 High
A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise.
CVE-2020-25717 5 Canonical, Debian, Fedoraproject and 2 more 28 Ubuntu Linux, Debian Linux, Fedora and 25 more 2024-11-21 8.1 High
A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation.
CVE-2020-25715 2 Dogtagpki, Redhat 3 Dogtagpki, Enterprise Linux, Rhel Eus 2024-11-21 6.1 Medium
A flaw was found in pki-core 10.9.0. A specially crafted POST request can be used to reflect a DOM-based cross-site scripting (XSS) attack to inject code into the search query form which can get automatically executed. The highest threat from this vulnerability is to data integrity.
