CVE-2018-12368 2 Microsoft, Mozilla 4 Windows 10, Firefox, Firefox Esr and 1 more 2019-10-02 9.3 HIGH 8.1 HIGH
Windows 10 does not warn users before opening executable files with the SettingContent-ms extension even when they have been downloaded from the internet and have the "Mark of the Web." Without the warning, unsuspecting users unfamiliar with this new file type might run an unwanted executable. This also allows a WebExtension with the limited downloads.open permission to execute arbitrary code without user interaction on Windows 10 systems. *Note: this issue only affects Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.
CVE-2018-12372 4 Canonical, Debian, Mozilla and 1 more 7 Ubuntu Linux, Debian Linux, Thunderbird and 4 more 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
Decrypted S/MIME parts, when included in HTML crafted for an attack, can leak plaintext when included in a a HTML reply/forward. This vulnerability affects Thunderbird < 52.9.
CVE-2017-7830 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Firefox Esr and 6 more 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
The Resource Timing API incorrectly revealed navigations in cross-origin iframes. This is a same-origin policy violation and could allow for data theft of URLs loaded by users. This vulnerability affects Firefox < 57, Firefox ESR < 52.5, and Thunderbird < 52.5.
CVE-2018-12392 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2019-10-02 7.5 HIGH 9.8 CRITICAL
When manipulating user events in nested loops while opening a document through script, it is possible to trigger a potentially exploitable crash due to poor event handling. This vulnerability affects Firefox < 63, Firefox ESR < 60.3, and Thunderbird < 60.3.
CVE-2017-7782 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2019-10-02 5.0 MEDIUM 5.3 MEDIUM
An error in the "WindowsDllDetourPatcher" where a RWX ("Read/Write/Execute") 4k block is allocated but never protected, violating DEP protections. Note: This attack only affects Windows operating systems. Other operating systems are not affected. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.
CVE-2018-12383 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2019-10-02 2.1 LOW 5.5 MEDIUM
If a user saved passwords before Firefox 58 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Firefox 58. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations. This vulnerability affects Firefox < 62, Firefox ESR < 60.2.1, and Thunderbird < 60.2.1.
CVE-2018-18505 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2019-10-02 7.5 HIGH 10.0 CRITICAL
An earlier fix for an Inter-process Communication (IPC) vulnerability, CVE-2011-3079, added authentication to communication between IPC endpoints and server parents during IPC process creation. This authentication is insufficient for channels created after the IPC process is started, leading to the authentication not being correctly applied to later channels. This could allow for a sandbox escape through IPC channels due to lack of message validation in the listener process. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65.
CVE-2018-5162 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Thunderbird and 7 more 2019-10-02 5.0 MEDIUM 7.5 HIGH
Plaintext of decrypted emails can leak through the src attribute of remote images, or links. This vulnerability affects Thunderbird ESR < 52.8 and Thunderbird < 52.8.
CVE-2017-7807 3 Debian, Mozilla, Redhat 10 Debian Linux, Firefox, Firefox Esr and 7 more 2019-10-02 5.8 MEDIUM 8.1 HIGH
A mechanism that uses AppCache to hijack a URL in a domain using fallback by serving the files from a sub-path on the domain. This has been addressed by requiring fallback files be inside the manifest directory. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.
CVE-2017-7765 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2019-10-02 5.0 MEDIUM 7.5 HIGH
The "Mark of the Web" was not correctly saved on Windows when files with very long names were downloaded from the Internet. Without the Mark of the Web data, the security warning that Windows displays before running executables downloaded from the Internet is not shown. Note: This attack only affects Windows operating systems. Other operating systems are unaffected. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.
CVE-2017-5426 2 Linux, Mozilla 3 Linux Kernel, Firefox, Thunderbird 2019-10-02 5.0 MEDIUM 5.3 MEDIUM
On Linux, if the secure computing mode BPF (seccomp-bpf) filter is running when the Gecko Media Plugin sandbox is started, the sandbox fails to be applied and items that would run within the sandbox are run protected only by the running filter which is typically weak compared to the sandbox. Note: this issue only affects Linux. Other operating systems are not affected. This vulnerability affects Firefox < 52 and Thunderbird < 52.
CVE-2018-5174 2 Microsoft, Mozilla 5 Windows 10, Firefox, Firefox Esr and 2 more 2019-10-02 5.0 MEDIUM 7.5 HIGH
In the Windows 10 April 2018 Update, Windows Defender SmartScreen honors the "SEE_MASK_FLAG_NO_UI" flag associated with downloaded files and will not show any UI. Files that are unknown and potentially dangerous will be allowed to run because SmartScreen will not prompt the user for a decision, and if the user is offline all files will be allowed to be opened because Windows won't prompt the user to ask what to do. Firefox incorrectly sets this flag when downloading files, leading to less secure behavior from SmartScreen. Note: this issue only affects Windows 10 users running the April 2018 update or later. It does not affect other Windows users or other operating systems. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.
CVE-2017-5405 3 Debian, Mozilla, Redhat 10 Debian Linux, Firefox, Firefox Esr and 7 more 2019-10-02 5.0 MEDIUM 5.3 MEDIUM
Certain response codes in FTP connections can result in the use of uninitialized values for ports in FTP operations. This vulnerability affects Firefox < 52, Firefox ESR < 45.8, Thunderbird < 52, and Thunderbird < 45.8.
CVE-2018-5185 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Thunderbird and 7 more 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
Plaintext of decrypted emails can leak through by user submitting an embedded form. This vulnerability affects Thunderbird ESR < 52.8 and Thunderbird < 52.8.
