EPSS score
1.64%
In 32-bit versions of Firefox, the Adobe Flash plugin setting for "Enable Adobe Flash protected mode" is unchecked by default even though the Adobe Flash sandbox is actually enabled. The displayed state is the reverse of the true setting, resulting in user confusion. This could cause users to select this setting intending to activate it and inadvertently turn protections off. This vulnerability affects Firefox < 60.

Mozilla developers backported selected changes in the Skia library. These changes correct memory corruption issues including invalid buffer reads and writes during graphic operations. This vulnerability affects Thunderbird ESR < 52.8, Thunderbird < 52.8, and Firefox ESR < 52.8.
7.5CVE-2018-5153canonicalubuntu_linux+2
EPSS score
1.65%
If websocket data is sent with mixed text and binary in a single message, the binary data can be corrupted. This can result in an out-of-bounds read with the read memory sent to the originating server in response. This vulnerability affects Firefox < 60.
9.8CVE-2018-5154canonicalubuntu_linux+15
EPSS score
3.19%
A use-after-free vulnerability can occur while enumerating attributes during SVG animations with clip paths. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.
9.8CVE-2018-5126canonicalubuntu_linux+4
EPSS score
1.77%
Memory safety bugs were reported in Firefox 58. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 59.
9.8CVE-2018-5116canonicalubuntu_linux+2
EPSS score
1.14%
WebExtensions with the "ActiveTab" permission are able to access frames hosted within the active tab even if the frames are cross-origin. Malicious extensions can inject frames from arbitrary origins into the loaded page and then interact with them, bypassing same-origin user expectations with this permission. This vulnerability affects Firefox < 58.
9.8CVE-2018-5188canonicalubuntu_linux+16
EPSS score
3.94%
Memory safety bugs present in Firefox 60, Firefox ESR 60, and Firefox ESR 52.8. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.
4.3CVE-2018-5108canonicalubuntu_linux+2
EPSS score
1.13%
A Blob URL can violate origin attribute segregation, allowing it to be accessed from a private browsing tab and for data to be passed between the private browsing tab and a normal tab. This could allow for the leaking of private information specific to the private browsing context. This issue is mitigated by the requirement that the user enter the Blob URL manually in order for the access violation to occur. This vulnerability affects Firefox < 58.
9.8CVE-2018-5187canonicalubuntu_linux+8
EPSS score
2.98%
Memory safety bugs present in Firefox 60 and Firefox ESR 60. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 60, Firefox ESR < 60.1, and Firefox < 61.
8.2CVE-2018-5141canonicalubuntu_linux+2
EPSS score
1.55%
A vulnerability in the notifications Push API where notifications can be sent through service workers by web content without direct user interaction. This could be used to open new tabs in a denial of service (DOS) attack or to display unwanted content from arbitrary URLs to users. This vulnerability affects Firefox < 59.
8.6CVE-2018-5129canonicalubuntu_linux+13
EPSS score
3.04%
A lack of parameter validation on IPC messages results in a potential out-of-bounds write through malformed IPC messages. This can potentially allow for sandbox escape through memory corruption in the parent process. This vulnerability affects Thunderbird < 52.7, Firefox ESR < 52.7, and Firefox < 59.
7.5CVE-2018-5113canonicalubuntu_linux+2
EPSS score
2.01%
The "browser.identity.launchWebAuthFlow" function of WebExtensions is only allowed to load content over "https:" but this requirement was not properly enforced. This can potentially allow privileged pages to be loaded by the extension. This vulnerability affects Firefox < 58.
9.8CVE-2018-5147debianfirefox-esr+6
EPSS score
2.39%
The libtremor library has the same flaw as CVE-2018-5146. This library is used by Firefox in place of libvorbis on Android and ARM platforms. This vulnerability affects Firefox ESR < 52.7.2 and Firefox < 59.0.1.
9.8CVE-2018-5103canonicalubuntu_linux+13
EPSS score
2.97%
A use-after-free vulnerability can occur during mouse event handling due to issues with multiprocess support. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58.
5.3CVE-2018-5109canonicalubuntu_linux+2
EPSS score
0.60%
An audio capture session can started under an incorrect origin from the site making the capture request. Users are still prompted to allow the request but the prompt can display the wrong origin, leading to user confusion about which site is making the request to capture an audio stream. This vulnerability affects Firefox < 58.
9.8CVE-2018-5122canonicalubuntu_linux+2
EPSS score
2.77%
A potential integer overflow in the "DoCrypt" function of WebCrypto was identified. If a means was found of exploiting it, it could result in an out-of-bounds write. This vulnerability affects Firefox < 58.
4.3CVE-2018-5167canonicalubuntu_linux+2
EPSS score
1.41%
The web console and JavaScript debugger do not sanitize all output that can be hyperlinked. Both will display "chrome:" links as active, clickable hyperlinks in their output. Web sites should not be able to directly link to internal chrome pages. Additionally, the JavaScript debugger will display "javascript:" links, which users could be tricked into clicking by malicious sites. This vulnerability affects Firefox < 60.
7.5CVE-2018-5135ubuntufirefox+1
EPSS score
1.50%
WebExtensions can bypass normal restrictions in some circumstances and use "browser.tabs.executeScript" to inject scripts into contexts where this should not be allowed, such as pages from other WebExtensions or unprivileged "about:" pages. This vulnerability affects Firefox < 59.
