CVE-2018-12365

A compromised IPC child process can escape the content sandbox and list the names of arbitrary files on the file system without user consent or interaction. This could result in exposure of private local files. This vulnerability affects Thunderbird 60, Thunderbird 52.9, Firefox ESR 60.1, Firefox...

CVE-2018-12366

An invalid grid size during QCMS color profile transformations can result in the out-of-bounds read interpreted as a float value. This could leak private data into the output. This vulnerability affects Thunderbird 60, Thunderbird 52.9, Firefox ESR 60.1, Firefox ESR 52.9, and Firefox 61...

CVE-2018-12361

An integer overflow can occur in the SwizzleData code while calculating buffer sizes. The overflowed value is used for subsequent graphics computations when their inputs are not sanitized which results in a potentially exploitable crash. This vulnerability affects Thunderbird 60, Firefox ESR 60.1...

CVE-2018-12362

An integer overflow can occur during graphics operations done by the Supplemental Streaming SIMD Extensions 3 SSSE3 scaler, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird 60, Thunderbird 52.9, Firefox ESR 60.1, Firefox ESR 52.9, and Firefox 61...

Memory corruption

Memory safety bugs present in Firefox 61 and Firefox ESR 60.1. 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 62, Firefox ESR 60.2, and Thunderbird 60.2....

Null pointer dereference

A vulnerability where the JavaScript JIT compiler inlines Array.prototype.push with multiple arguments that results in the stack pointer being off by 8 bytes after a bailout. This leaks a memory address to the calling function which can be used as part of an exploit inside the sandboxed content...

Memory corruption

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,...

Out-of-bounds

An invalid grid size during QCMS color profile transformations can result in the out-of-bounds read interpreted as a float value. This could leak private data into the output. This vulnerability affects Thunderbird 60, Thunderbird 52.9, Firefox ESR 60.1, Firefox ESR 52.9, and Firefox 61...

CVE-2018-12381

Manually dragging and dropping an Outlook email message into the browser will trigger a page navigation when the message's mail columns are incorrectly interpreted as a URL. Note: this issue only affects Windows operating systems with Outlook installed. Other operating systems are not affected...

Code injection

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. Th...

Code injection

A compromised IPC child process can escape the content sandbox and list the names of arbitrary files on the file system without user consent or interaction. This could result in exposure of private local files. This vulnerability affects Thunderbird 60, Thunderbird 52.9, Firefox ESR 60.1, Firefox...

Type confusion

A vulnerability in register allocation in JavaScript can lead to type confusion, allowing for an arbitrary read and write. This leads to remote code execution inside the sandboxed content process when triggered. This vulnerability affects Firefox ESR 60.2.2 and Firefox 62.0.3...

Design/Logic Flaw

In the previous mitigations for Spectre, the resolution or precision of various methods was reduced to counteract the ability to measure precise time intervals. In that work PerformanceNavigationTiming was not adjusted but it was found that it could be used as a precision timer. This vulnerabilit...

Design/Logic Flaw

WebExtensions bundled with embedded experiments were not correctly checked for proper authorization. This allowed a malicious WebExtension to gain full browser permissions. This vulnerability affects Firefox ESR 60.1 and Firefox 61...

CVE-2018-12359

A buffer overflow can occur when rendering canvas content while adjusting the height and width of the canvas element dynamically, causing data to be written outside of the currently computed boundaries. This results in a potentially exploitable crash. This vulnerability affects Thunderbird 60,...

Integer overflow

An integer overflow can occur in the SwizzleData code while calculating buffer sizes. The overflowed value is used for subsequent graphics computations when their inputs are not sanitized which results in a potentially exploitable crash. This vulnerability affects Thunderbird 60, Firefox ESR 60.1...

Memory corruption

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...

Cross site request forgery (csrf)

NPAPI plugins, such as Adobe Flash, can send non-simple cross-origin requests, bypassing CORS by making a same-origin POST that does a 307 redirect to the target site. This allows for a malicious site to engage in cross-site request forgery CSRF attacks. This vulnerability affects Thunderbird 60,...

Design/Logic Flaw

A potentially exploitable crash in TransportSecurityInfo used for SSL can be triggered by data stored in the local cache in the user profile directory. This issue is only exploitable in combination with another vulnerability allowing an attacker to write data into the local cache or from locally...
