mozilla-nss was updated to NSS 3.28.3

  - This is a patch release to fix binary compatibility     issues. NSS version 3.28, 3.28.1 and 3.28.2 contained     changes that were in violation with the NSS     compatibility promise. ECParams, which is part of the     public API of the freebl/softokn parts of NSS, had been     changed to include an additional attribute. That size     increase caused crashes or malfunctioning with     applications that use that data structure directly, or     indirectly through ECPublicKey, ECPrivateKey,     NSSLOWKEYPublicKey, NSSLOWKEYPrivateKey, or potentially     other data structures that reference ECParams. The     change has been reverted to the original state in bug     bmo#1334108. SECKEYECPublicKey had been extended with a     new attribute, named 'encoding'. If an application     passed type SECKEYECPublicKey to NSS (as part of     SECKEYPublicKey), the NSS library read the uninitialized     attribute. With this NSS release     SECKEYECPublicKey.encoding is deprecated. NSS no longer     reads the attribute, and will always set it to     ECPoint_Undefined. See bug bmo#1340103.

  - requires NSPR >= 4.13.1

  - update to NSS 3.28.2 This is a stability and     compatibility release. Below is a summary of the     changes.

  - Fixed a NSS 3.28 regression in the signature scheme     flexibility that causes connectivity issues between iOS     8 clients and NSS servers with ECDSA certificates     (bmo#1334114)

  - Fixed a possible crash on some Windows systems     (bmo#1323150)

  - Fixed a compatibility issue with TLS clients that do not     provide a list of supported key exchange groups     (bmo#1330612)

    (CVE-2017-5469)

  - An out-of-bounds read while processing SVG content in     ConvolvePixel. This results in a crash and also allows     for otherwise inaccessible memory being copied into SVG     graphic content, which could then displayed. This     vulnerability affects Thunderbird < 52.1, Firefox ESR <     45.9, Firefox ESR < 52.1, and Firefox < 53.
    (CVE-2017-5465)

  - If a page is loaded from an original site through a     hyperlink and contains a redirect to a data:text/html     URL, triggering a reload will run the reloaded     data:text/html page with its origin set incorrectly.
    This allows for a cross-site scripting (XSS) attack.
    This vulnerability affects Thunderbird < 52.1, Firefox     ESR < 52.1, and Firefox < 53. (CVE-2017-5466)

  - A use-after-free vulnerability in SMIL animation     functions occurs when pointers to animation elements in     an array are dropped from the animation controller while     still in use.

  - A use-after-free vulnerability in IndexedDB when one of     its objects is destroyed in memory while a method on it     is still being executed. This results in a potentially     exploitable crash. This vulnerability affects Firefox <     54, Firefox ESR < 52.2, and Thunderbird < 52.2.
    (CVE-2017-7757)

  - A number of security vulnerabilities in the Graphite 2     library including out-of-bounds reads, buffer overflow     reads and writes, and the use of uninitialized memory.
    These issues were addressed in Graphite 2 version     1.3.10. This vulnerability affects Firefox < 54, Firefox     ESR < 52.2, and Thunderbird < 52.2. (CVE-2017-7778)

  - An out of bounds read vulnerability was found in     libevent in the search_make_new function. If an attacker     could cause an application using libevent to attempt     resolving an empty hostname, an out of bounds read could     occur possibly leading to a crash. (CVE-2016-10197)

  - A vulnerability was found in libevent with the parsing     of DNS requests and replies. An attacker could send a     forged DNS response to an application using libevent     which could lead to reading data out of bounds on the     heap, potentially disclosing a small amount of     application memory. (CVE-2016-10195)

  - A vulnerability was found in libevent with the parsing     of IPv6 addresses. If an attacker could cause an     application using libevent to parse a malformed address     in IPv6 notation of more than 2GiB in length, a stack     overflow would occur leading to a crash.
    (CVE-2016-10196)

  - A use-after-free vulnerability during video control     operations when a  element holds a reference to     an older window if that window has been replaced in the     DOM. This results in a potentially exploitable crash.
    This vulnerability affects Firefox < 54, Firefox ESR <     52.2, and Thunderbird < 52.2. (CVE-2017-7750)

This vulnerability affects Firefox < 54, Firefox     ESR < 52.2, and Thunderbird < 52.2. (CVE-2017-5470)

  - An out of bounds read flaw related to     graphite2::Silf::readGraphite has been reported in     graphite2. An attacker could possibly exploit this flaw     to disclose potentially sensitive memory or cause an     application crash. (CVE-2017-7774)

  - A heap-based buffer overflow flaw related to     lz4::decompress (src/Decompressor) has been reported     in graphite2. An attacker could exploit this issue to     cause a crash or, possibly, execute arbitrary code.
    (CVE-2017-7773)

  - A heap-based buffer overflow flaw related to     lz4::decompress has been reported in graphite2. An     attacker could exploit this issue to cause a crash or,     possibly, execute arbitrary code. (CVE-2017-7772)

  - An out of bounds read flaw related to     graphite2::Pass::readPass has been reported in     graphite2. An attacker could possibly exploit this flaw     to disclose potentially sensitive memory or cause an     application crash. (CVE-2017-7771)

  - The use of uninitialized memory related to     graphite2::GlyphCache::Loader::read_glyph has been     reported in graphite2. An attacker could possibly     exploit this flaw to negatively impact the execution of     an application using graphite2 in unknown ways.
    (CVE-2017-7777)

  - An out of bounds read flaw related to     graphite2::Silf::getClassGlyph has been reported in     graphite2. An attacker could possibly exploit this flaw     to disclose potentially sensitive memory or cause an     application crash. (CVE-2017-7776)

  - Characters from the Canadian Syllabics unicode block     can be mixed with characters from other unicode blocks     in the addressbar instead of being rendered as their raw     punycode form, allowing for domain name spoofing     attacks through character confusion. The current Unicode     standard allows characters from Aspirational Use     Scripts such as Canadian Syllabics to be mixed with     Latin characters in the moderately restrictive IDN     profile. We have changed Firefox behavior to match the     upcoming Unicode version 10.0 which removes this     category and treats them as Limited Use Scripts.. This     vulnerability affects Firefox < 54, Firefox ESR < 52.2,     and Thunderbird < 52.2. (CVE-2017-7764)

  - Memory safety bugs were reported in Firefox 52, Firefox     ESR 45.8, Firefox ESR 52, and Thunderbird 52. 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 < 52.1, Firefox ESR < 45.9, Firefox     ESR < 52.1, and Firefox < 53. (CVE-2017-5429)

  - A vulnerability while parsing application/http-index-     format format content where uninitialized values are     used to create an array. This could allow the reading of     uninitialized memory into the arrays affected. This     vulnerability affects Thunderbird < 52.1, Firefox ESR <     45.9, Firefox ESR < 52.1, and Firefox < 53.
    (CVE-2017-5445)

  - A use-after-free vulnerability during XSLT processing     due to a failure to propagate error conditions during     matching while evaluating context, leading to objects     being used when they no longer exist. This results in a     potentially exploitable crash. This vulnerability     affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox     ESR < 52.1, and Firefox < 53. (CVE-2017-5440)

  - An out-of-bounds write in the Graphite 2 library     triggered with a maliciously crafted Graphite font. This     results in a potentially exploitable crash. This issue     was fixed in the Graphite 2 library as well as Mozilla     products. This vulnerability affects Thunderbird < 52.1,     Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox <     53. (CVE-2017-5436)

The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 45.8. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2017-06 advisory.

  - Mozilla developers and community members Boris Zbarsky, Christian Holler, Honza Bambas, Jon Coppeard,     Randell Jesup, Andr Bargull, Kan-Ru Chen, and Nathan Froyd reported memory safety bugs present in     Firefox 51 and Firefox ESR 45.7. 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-2017-5398)

  - 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-2017-5410)

  - 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-2017-5400)

  - A crash triggerable by web content in which an <code>ErrorResult</code> references unassigned memory due     to a logic error. The resulting crash may be exploitable. (CVE-2017-5401)

  - A use-after-free can occur when events are fired for a <code>FontFace</code> object after the object has     been already been destroyed while working with fonts. This results in a potentially exploitable crash.
    (CVE-2017-5402)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Multiple security issues have been found in Thunderbird, which may may lead to the execution of arbitrary code or information leaks.

With this update, the Icedove packages are de-branded back to the official Mozilla branding. With the removing of the Debian branding the packages are also renamed back to the official names used by Mozilla.

The Thunderbird package is using a different default profile folder, the default profile folder is now '\$(HOME)/.thunderbird'. The users profile folder, that was used in Icedove, will get migrated to the new profile folder on the first start, that can take a little bit more time.

Please read README.Debian for getting more information about the changes.

This update upgrades Thunderbird to version 45.8.0.

Security Fix(es) :

  - Multiple flaws were found in the processing of malformed     web content. A web page containing malicious content     could cause Thunderbird to crash or, potentially,     execute arbitrary code with the privileges of the user     running Thunderbird. (CVE-2017-5398, CVE-2017-5400,     CVE-2017-5401, CVE-2017-5402, CVE-2017-5404,     CVE-2017-5407, CVE-2017-5408, CVE-2017-5410,     CVE-2017-5405)
