Other platforms are unaffected.*. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. | ||||
| CVE-2021-29955 | 1 Mozilla | 2 Firefox, Firefox Esr | 2021-06-30 | 5.3 Medium |
| A transient execution vulnerability, named Floating Point Value Injection (FPVI) allowed an attacker to leak arbitrary memory addresses and may have also enabled JIT type confusion attacks. (A related vulnerability, Speculative Code Store Bypass (SCSB), did not affect Firefox.). This vulnerability affects Firefox ESR < 78.9 and Firefox < 87. | ||||
| CVE-2021-29946 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-06-25 | 8.8 High |
| 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. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. | ||||
| CVE-2014-1520 | 3 Fedoraproject, Microsoft, Mozilla | 4 Fedora, Windows, Firefox and 1 more | 2021-03-17 | N/A |
| maintenservice_installer.exe in the Maintenance Service Installer in Mozilla Firefox before 29.0 and Firefox ESR 24.x before 24.5 on Windows allows local users to gain privileges by placing a Trojan horse DLL file into a temporary directory at an unspecified point in the update process. | ||||
| CVE-2013-0800 | 5 Canonical, Debian, Mozilla and 2 more | 11 Ubuntu Linux, Debian Linux, Firefox and 8 more | 2021-03-11 | N/A |
| Integer signedness error in the pixman_fill_sse2 function in pixman-sse2.c in Pixman, as distributed with Cairo and used in Mozilla Firefox before 20.0, Firefox ESR 17.x before 17.0.5, Thunderbird before 17.0.5, Thunderbird ESR 17.x before 17.0.5, SeaMonkey before 2.17, and other products, allows remote attackers to execute arbitrary code via crafted values that trigger attempted use of a (1) negative box boundary or (2) negative box size, leading to an out-of-bounds write operation. | ||||
| CVE-2021-23953 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-03-03 | 4.3 Medium |
| If a user clicked into a specifically crafted PDF, the PDF reader could be confused into leaking cross-origin information, when said information is served as chunked data. This vulnerability affects Firefox < 85, Thunderbird < 78.7, and Firefox ESR < 78.7. | ||||
| CVE-2021-23954 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-03-03 | 8.8 High |
| Using the new logical assignment operators in a JavaScript switch statement could have caused a type confusion, leading to a memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 85, Thunderbird < 78.7, and Firefox ESR < 78.7. | ||||
| CVE-2021-23960 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-03-03 | 8.8 High |

| When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the block size, a small out of bounds write could occur. This could have caused heap corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71. | ||||
| CVE-2020-35113 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-01-12 | 8.8 High |
| Mozilla developers reported memory safety bugs present in Firefox 83 and Firefox ESR 78.5.

Other operating systems are unaffected.*. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6. | ||||
| CVE-2020-35111 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-01-12 | 4.3 Medium |

This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6. | ||||
| CVE-2020-26978 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-01-12 | 6.1 Medium |
| Using techniques that built on the slipstream research, a malicious webpage could have exposed both an internal network's hosts as well as services running on the user's local machine. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6. | ||||
| CVE-2020-26974 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-01-12 | 8.8 High |
| When flex-basis was used on a table wrapper, a StyleGenericFlexBasis object could have been incorrectly cast to the wrong type.
