www-client/firefox{,-bin}-51.x (unstable in Gentoo) specific vulnerabilities addressed in 52.x (from https://www.mozilla.org/en-US/security/advisories/mfsa2017-05/):
CVE-2017-5403: Use-after-free using addRange to add range to an incorrect
root object
Impact
critical
Description
When adding a range to an object in the DOM, it is possible to use
addRange to add the range to an incorrect root object. This triggers a
use-after-free, resulting in a potentially exploitable crash.
CVE-2017-5406: Segmentation fault in Skia with canvas operations
Impact
high
Description
A segmentation fault can occur in the Skia graphics library during some
canvas operations due to issues with mask/clip intersection and empty
masks.
CVE-2017-5411: Use-after-free in Buffer Storage in libGLES
Impact
high
Description
A use-after-free can occur during buffer storage operations within the
ANGLE graphics library, used for WebGL content. The buffer storage can
be freed while still in use in some circumstances, leading to a
potentially exploitable crash.
Note: This issue is in libGLES, which is only in use on Windows. Other
operating systems are not affected.
CVE-2017-5412: Buffer overflow read in SVG filters
Impact
moderate
Description
A buffer overflow read during SVG filter color value operations,
resulting in data exposure.
CVE-2017-5413: Segmentation fault during bidirectional operations
Impact
moderate
Description
A segmentation fault can occur during some bidirectional layout
operations.
CVE-2017-5414: File picker can choose incorrect default directory
Impact
moderate
Description
The file picker dialog can choose and display the wrong local default
directory when instantiated. On some operating systems, this can lead
to information disclosure, such as the operating system or the local
account name.
CVE-2017-5415: Addressbar spoofing through blob URL
Impact
moderate
Description
An attack can use a blob URL and script to spoof an arbitrary
addressbar URL prefaced by blob: as the protocol, leading to user
confusion and further spoofing attacks.
CVE-2017-5416: Null dereference crash in HttpChannel
Impact
moderate
Description
In certain circumstances a networking event listener can be prematurely
released. This appears to result in a null dereference in practice.
CVE-2017-5417: Addressbar spoofing by draging and dropping URLs
Impact
moderate
Description
When dragging content from the primary browser pane to the addressbar
on a malicious site, it is possible to change the addressbar so that
the displayed location following navigation does not match the URL of
the newly loaded page. This allows for spoofing attacks.
CVE-2017-5425: Overly permissive Gecko Media Plugin sandbox regular
expression access
Impact
moderate
Description
The Gecko Media Plugin sandbox allows access to local files that match
specific regular expressions. On OS OX, this matching allows access to
some data in subdirectories of /private/var that could expose personal
or temporary data. This has been updated to not allow access to
/private/var and its subdirectories.
Note: this issue only affects OS X. Other operating systems are not
affected.
CVE-2017-5426: Gecko Media Plugin sandbox is not started if seccomp-bpf
filter is running
Impact
moderate
Description
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.
CVE-2017-5427: Non-existent chrome.manifest file loaded during startup
Impact
moderate
Description
A non-existent chrome.manifest file will attempt to be loaded during
startup from the primary installation directory. If a malicious user
with local access puts chrome.manifest and other referenced files in
this directory, they will be loaded and activated during startup. This
could result in malicious software being added without consent or
modification of referenced installed files.
CVE-2017-5418: Out of bounds read when parsing HTTP digest authorization
responses
Impact
low
Description
An out of bounds read error occurs when parsing some HTTP digest
authorization responses, resulting in information leakage through the
reading of random memory containing matches to specifically set
patterns.
CVE-2017-5419: Repeated authentication prompts lead to DOS attack
Impact
low
Description
If a malicious site repeatedly triggers a modal authentication prompt,
eventually the browser UI will become non-responsive, requiring
shutdown through the operating system. This is a denial of service
(DOS) attack.
CVE-2017-5420: Javascript: URLs can obfuscate addressbar location
Impact
low
Description
A javascript: url loaded by a malicious page can obfuscate its location
by blanking the URL displayed in the addressbar, allowing for an
attacker to spoof an existing page without the malicious page's
address being displayed correctly.
CVE-2017-5421: Print preview spoofing
Impact
low
Description
A malicious site could spoof the contents of the print preview window
if popup windows are enabled, resulting in user confusion of what site
is currently loaded.
CVE-2017-5422: DOS attack by using view-source: protocol repeatedly in one
hyperlink
Impact
low
Description
If a malicious site uses the view-source: protocol in a series within
a single hyperlink, it can trigger a non-exploitable browser crash when
the hyperlink is selected. This was fixed by no longer making
view-source: linkable.
CVE-2017-5399: Memory safety bugs fixed in Firefox 52
Impact
critical
Description
Mozilla developers and community members Carsten Book, Calixte Denizet,
Christian Holler, Andrew McCreight, David Bolter, David Keeler, Jon
Coppeard, Tyson Smith, Ronald Crane, Tooru Fujisawa, Ben Kelly, Bob
Owen, Jed Davis, Julian Seward, Julian Hector, Philipp, Markus Stange,
and André Bargull reported memory safety bugs present in Firefox 51.
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.

From $URL: CVE-2017-5400: asm.js JIT-spray bypass of ASLR and DEP Impact critical Description JIT-spray targeting asm.js combined with a heap spray allows for a bypass of ASLR and DEP protections leading to potential memory corruption attacks. CVE-2017-5401: Memory Corruption when handling ErrorResult Impact critical Description A crash triggerable by web content in which an ErrorResult references unassigned memory due to a logic error. The resulting crash may be exploitable. CVE-2017-5402: Use-after-free working with events in FontFace objects Impact critical Description A use-after-free can occur when events are fired for a FontFace object after the object has been already been destroyed while working with fonts. This results in a potentially exploitable crash. CVE-2017-5404: Use-after-free working with ranges in selections Impact critical Description A use-after-free error can occur when manipulating ranges in selections with one node inside a native anonymous tree and one node outside of it. This results in a potentially exploitable crash. CVE-2017-5407: Pixel and history stealing via floating-point timing side channel with SVG filters Impact high Description Using SVG filters that don't use the fixed point math implementation on a target iframe, a malicious page can extract pixel values from a targeted user. This can be used to extract history information and read text values across domains. This violates same-origin policy and leads to information disclosure. CVE-2017-5410: Memory corruption during JavaScript garbage collection incremental sweeping Impact high Description Memory corruption resulting in a potentially exploitable crash during garbage collection of JavaScript due errors in how incremental sweeping is managed for memory cleanup. CVE-2017-5409: File deletion via callback parameter in Mozilla Windows Updater and Maintenance Service Impact moderate Description The Mozilla Windows updater can be called by a non-privileged user to delete an arbitrary local file by passing a special path to the callback parameter through the Mozilla Maintenance Service, which has privileged access. Note: This attack requires local system access and only affects Windows. Other operating systems are not affected. CVE-2017-5408: Cross-origin reading of video captions in violation of CORS Impact moderate Description Video files loaded video captions cross-origin without checking for the presence of CORS headers permitting such cross-origin use, leading to potential information disclosure for video captions. CVE-2017-5405: FTP response codes can cause use of uninitialized values for ports Impact low Description Certain response codes in FTP connections can result in the use of uninitialized values for ports in FTP operations.
