This is a port of the current state of thunderbird from the master branch. We did miss a bunch of security fixes when thunderbird 60 was released. This is an attempt to take a shortcut by simply copying over the expression from the master branch. Security related fixes in this release are: - CVE-2018-12359: Buffer overflow using computed size of canvas element 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. - CVE-2018-12360: Use-after-free when using focus() A use-after-free vulnerability can occur when deleting an input element during a mutation event handler triggered by focusing that element. This results in a potentially exploitable crash. - CVE-2018-12361: Integer overflow in SwizzleData 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. - CVE-2018-12362: Integer overflow in SSSE3 scaler An integer overflow can occur during graphics operations done by the Supplemental Streaming SIMD Extensions 3 (SSSE3) scaler, resulting in a potentially exploitable crash. - CVE-2018-5156: Media recorder segmentation fault when track type is changed during capture A vulnerability can occur when capturing a media stream when the media source type is changed as the capture is occuring. This can result in stream data being cast to the wrong type causing a potentially exploitable crash. - CVE-2018-12363: Use-after-free when appending DOM nodes A use-after-free vulnerability can occur when script uses mutation events to move DOM nodes between documents, resulting in the old document that held the node being freed but the node still having a pointer referencing it. This results in a potentially exploitable crash. - CVE-2018-12364: CSRF attacks through 307 redirects and NPAPI plugins 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. - CVE-2018-12365: Compromised IPC child process can list local filenames 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. - CVE-2018-12371: Integer overflow in Skia library during edge builder allocation An integer overflow vulnerability in the Skia library when allocating memory for edge builders on some systems with at least 16 GB of RAM. This results in the use of uninitialized memory, resulting in a potentially exploitable crash. - CVE-2018-12366: Invalid data handling during QCMS transformations 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. - CVE-2018-12367: Timing attack mitigation of PerformanceNavigationTiming 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. - CVE-2018-5187: Memory safety bugs fixed in Firefox 61, Firefox ESR 60.1, and Thunderbird 60 Mozilla developers and community members Christian Holler, Sebastian Hengst, Nils Ohlmeier, Jon Coppeard, Randell Jesup, Ted Campbell, Gary Kwong, and Jean-Yves Avenard reported 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. - CVE-2018-5188: Memory safety bugs fixed in Firefox 61, Firefox ESR 60.1, Firefox ESR 52.9, and Thunderbird 60 Mozilla developers and community members Alex Gaynor, Christoph Diehl, Christian Holler, Jason Kratzer, David Major, Jon Coppeard, Nicolas B. Pierron, Jason Kratzer, Marcia Knous, and Ronald Crane reported 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.
Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels git://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-18.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-18.03
For pull-requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
