This update for MozillaFirefox to version 60.5.1esr fixes the following issues :

Security vulnerabilities addressed (MFSA-2019-05, boo#1125330) :

  - CVE-2018-18356: Fixed a use-after-free vulnerability in     the Skia library that could occur when creating a path,     leading to a potentially exploitable crash.

  - CVE-2019-5785: Fixed an integer overflow vulnerability     in the Skia library that could occur after specific     transform operations, leading to a potentially     exploitable crash.

The version of Thunderbird installed on the remote Windows host is prior to 60.5.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-06 advisory.

  - A use-after-free vulnerability in the Skia library can occur when creating a path, leading to a     potentially exploitable crash. (CVE-2018-18356)

  - An integer overflow vulnerability in the Skia library can occur after specific transform operations,     leading to a potentially exploitable crash. (CVE-2019-5785)

  - A buffer overflow vulnerability in the Skia library can occur with Canvas 2D acceleration on macOS. This     issue was addressed by disabling Canvas 2D acceleration in Firefox ESR.  Note: this does not affect other     versions and platforms where Canvas 2D acceleration is already disabled by default. (CVE-2018-18335)

  - A flaw during verification of certain S/MIME signatures causes emails to be shown in Thunderbird as having     a valid digital signature, even if the shown message contents aren't covered by the signature. The flaw     allows an attacker to reuse a valid S/MIME signature to craft an email message with arbitrary content.
    (CVE-2018-18509)

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

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3897-1 advisory.

    A use-after-free was discovered in libical. If a user were tricked in to opening a specially crafted ICS     calendar file, an attacker could potentially exploit this to cause a denial of service. (CVE-2016-5824)

    Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially     crafted message, an attacker could potentially exploit these to cause a denial of service, or execute     arbitrary code. (CVE-2018-18356, CVE-2018-18500, CVE-2019-5785)

    Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially     crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of     service, gain additional privileges by escaping the sandbox, or execute arbitrary code. (CVE-2018-18501,     CVE-2018-18505)

    An issue was discovered with S/MIME signature verification in some circumstances. An attacker could     potentially exploit this by spoofing signatures for arbitrary content. (CVE-2018-18509)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Other bug fixes and changes :

  - FileLink provider WeTransfer to upload large attachments

  - Thunderbird now allows the addition of OpenSearch search     engines from a local XML file using a minimal user     interface: [+] button to select a file an add, [-] to     remove.

  - More search engines: Google and DuckDuckGo available by     default in some locales

  - During account creation, Thunderbird will now detect     servers using the Microsoft Exchange protocol. It will     offer the installation of a 3rd party add-on (Owl) which     supports that protocol.

  - Thunderbird now compatible with other WebExtension-based     FileLink add-ons like the Dropbox add-on

  - New WebExtensions FileLink API to facilitate add-ons

  - Fix decoding problems for messages with less common     charsets (cp932, cp936)

  - New messages in the drafts folder (and other special or     virtual folders) will no longer be included in the new     messages notification

  - Thunderbird 60 will migrate security databases (key3.db,     cert8.db to key4.db, cert9.db).

  - Address book search and auto-complete slowness

  - Plain text markup with * for bold, / for italics, _ for     underline and | for code did not work when the enclosed     text contained non-ASCII characters

  - While composing a message, a link not removed when link     location was removed in the link properties panel

  - Encoding problems when exporting address books or     messages using the system charset. Messages are now     always exported using the UTF-8 encoding

  - If the 'Date' header of a message was invalid, Jan 1970     or Dec 1969 was displayed. Now using date from     'Received' header instead.

  - Body search/filtering didn't reliably ignore content of     tags

  - Inappropriate warning 'Thunderbird prevented the site     (addons.thunderbird.net) from asking you to install     software on your computer' when installing add-ons

  - Incorrect display of correspondents column since own     email address was not always detected

  - Spurious (encoded newline) inserted into drafts and sent     email

  - Double-clicking on a word in the Write window sometimes     launched the Advanced Property Editor or Link Properties     dialog

  - Fixed Cookie removal

  - 'Download rest of message' was not working if global     inbox was used

  - Fix Encoding problems for users (especially in Poland)     when a file was sent via a folder using 'Sent to > Mail     recipient' due to a problem in the Thunderbird MAPI     interface

  - According to RFC 4616 and RFC 5721, passwords containing     non-ASCII characters are encoded using UTF-8 which can     lead to problems with non-compliant providers, for     example office365.com. The SMTP LOGIN and POP3 USER/PASS     authentication methods are now using a Latin-1 encoding     again to work around this issue

  - Fix shutdown crash/hang after entering an empty IMAP     password

The remote NewStart CGSL host, running version MAIN 4.05, has firefox packages installed that are affected by multiple vulnerabilities:

  - Incorrect convexity calculations in Skia in Google     Chrome prior to 72.0.3626.81 allowed a remote attacker     to perform an out of bounds memory write via a crafted     HTML page. (CVE-2019-5785)

  - The type inference system allows the compilation of     functions that can cause type confusions between     arbitrary objects when compiled through the IonMonkey     just-in-time (JIT) compiler and when the constructor     function is entered through on-stack replacement (OSR).
    This allows for possible arbitrary reading and writing     of objects during an exploitable crash. This     vulnerability affects Thunderbird < 60.6, Firefox ESR <     60.6, and Firefox < 66. (CVE-2019-9791)

  - Incorrect alias information in IonMonkey JIT compiler     for Array.prototype.slice method may lead to missing     bounds check and a buffer overflow. This vulnerability     affects Firefox < 66.0.1, Firefox ESR < 60.6.1, and     Thunderbird < 60.6.1. (CVE-2019-9810)

  - Incorrect handling of __proto__ mutations may lead to     type confusion in IonMonkey JIT code and can be     leveraged for arbitrary memory read and write. This     vulnerability affects Firefox < 66.0.1, Firefox ESR <     60.6.1, and Thunderbird < 60.6.1. (CVE-2019-9813)

  - When proxy auto-detection is enabled, if a web server     serves a Proxy Auto-Configuration (PAC) file or if a PAC     file is loaded locally, this PAC file can specify that     requests to the localhost are to be sent through the     proxy to another server. This behavior is disallowed by     default when a proxy is manually configured, but when     enabled could allow for attacks on services and tools     that bind to the localhost for networked behavior if     they are accessed through browsing. This vulnerability     affects Firefox < 65. (CVE-2018-18506)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox 65, Firefox ESR 60.5, and     Thunderbird 60.5. 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 < 60.6,     Firefox ESR < 60.6, and Firefox < 66. (CVE-2019-9788)

  - A use-after-free vulnerability can occur when a raw     pointer to a DOM element on a page is obtained using     JavaScript and the element is then removed while still     in use. This results in a potentially exploitable crash.
    This vulnerability affects Thunderbird < 60.6, Firefox     ESR < 60.6, and Firefox < 66. (CVE-2019-9790)

  - The IonMonkey just-in-time (JIT) compiler can leak an     internal JS_OPTIMIZED_OUT magic value to the running     script during a bailout. This magic value can then be     used by JavaScript to achieve memory corruption, which     results in a potentially exploitable crash. This     vulnerability affects Thunderbird < 60.6, Firefox ESR <     60.6, and Firefox < 66. (CVE-2019-9792)

  - A mechanism was discovered that removes some bounds     checking for string, array, or typed array accesses if     Spectre mitigations have been disabled. This     vulnerability could allow an attacker to create an     arbitrary value in compiled JavaScript, for which the     range analysis will infer a fully controlled, incorrect     range in circumstances where users have explicitly     disabled Spectre mitigations. *Note: Spectre mitigations     are currently enabled for all users by default     settings.*. This vulnerability affects Thunderbird <     60.6, Firefox ESR < 60.6, and Firefox < 66.
    (CVE-2019-9793)

  - A vulnerability where type-confusion in the IonMonkey     just-in-time (JIT) compiler could potentially be used by     malicious JavaScript to trigger a potentially     exploitable crash. This vulnerability affects     Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox <     66. (CVE-2019-9795)

  - A use-after-free vulnerability can occur when the SMIL     animation controller incorrectly registers with the     refresh driver twice when only a single registration is     expected. When a registration is later freed with the     removal of the animation controller element, the refresh     driver incorrectly leaves a dangling pointer to the     driver's observer array. This vulnerability affects     Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox <     66. (CVE-2019-9796)

  - An integer overflow in path handling lead to a use after     free in Skia in Google Chrome prior to 71.0.3578.80     allowed a remote attacker to potentially exploit heap     corruption via a crafted HTML page. (CVE-2018-18356)

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