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, conduct cross-site scripting (XSS) attacks, or execute arbitrary code. (CVE-2019-17005, CVE-2019-17008, CVE-2019-17010, CVE-2019-17011, CVE-2019-17012, CVE-2019-17016, CVE-2019-17017, CVE-2019-17022, CVE-2019-17024, CVE-2019-17026)

It was discovered that NSS incorrectly handled certain memory operations. A remote attacker could potentially exploit this to cause a denial of service, or execute arbitrary code. (CVE-2019-11745).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has thunderbird packages installed that are affected by multiple vulnerabilities:

  - In libexpat before 2.2.8, crafted XML input could fool     the parser into changing from DTD parsing to document     parsing too early; a consecutive call to     XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber)     then resulted in a heap-based buffer over-read.
    (CVE-2019-15903)

  - When following the value's prototype chain, it was     possible to retain a reference to a locale, delete it,     and subsequently reference it. This resulted in a use-     after-free and a potentially exploitable crash. This     vulnerability affects Firefox < 70, Thunderbird < 68.2,     and Firefox ESR < 68.2. (CVE-2019-11757)

  - Mozilla community member Philipp reported a memory     safety bug present in Firefox 68 when 360 Total Security     was installed. This bug showed evidence of memory     corruption in the accessibility engine and we presume     that with enough effort that it could be exploited to     run arbitrary code. This vulnerability affects Firefox <     69, Thunderbird < 68.2, and Firefox ESR < 68.2.
    (CVE-2019-11758)

  - If two same-origin documents set document.domain     differently to become cross-origin, it was possible for     them to call arbitrary DOM methods/getters/setters on     the now-cross-origin window. This vulnerability affects     Firefox < 70, Thunderbird < 68.2, and Firefox ESR <     68.2. (CVE-2019-11762)

  - Failure to correctly handle null bytes when processing     HTML entities resulted in Firefox incorrectly parsing     these entities. This could have led to HTML comment text     being treated as HTML which could have led to XSS in a     web application under certain conditions. It could have     also led to HTML entities being masked from filters -     enabling the use of entities to mask the actual     characters of interest from filters. This vulnerability     affects Firefox < 70, Thunderbird < 68.2, and Firefox     ESR < 68.2. (CVE-2019-11763)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox 69 and Firefox ESR 68.1.
    Some of these bugs showed evidence of memory corruption     and we presume that with enough effort some of these     could be exploited to run arbitrary code. This     vulnerability affects Firefox < 70, Thunderbird < 68.2,     and Firefox ESR < 68.2. (CVE-2019-11764)

  - An attacker could have caused 4 bytes of HMAC output to     be written past the end of a buffer stored on the stack.
    This could be used by an attacker to execute arbitrary     code or more likely lead to a crash. This vulnerability     affects Firefox < 70, Thunderbird < 68.2, and Firefox     ESR < 68.2. (CVE-2019-11759)

  - A fixed-size stack buffer could overflow in nrappkit     when doing WebRTC signaling. This resulted in a     potentially exploitable crash in some instances. This     vulnerability affects Firefox < 70, Thunderbird < 68.2,     and Firefox ESR < 68.2. (CVE-2019-11760)

  - By using a form with a data URI it was possible to gain     access to the privileged JSONView object that had been     cloned into content. Impact from exposing this object     appears to be minimal, however it was a bypass of     existing defense in depth mechanisms. This vulnerability     affects Firefox < 70, Thunderbird < 68.2, and Firefox     ESR < 68.2. (CVE-2019-11761)

  - Under certain conditions, when checking the Resist     Fingerprinting preference during device orientation     checks, a race condition could have caused a use-after-     free and a potentially exploitable crash. This     vulnerability affects Thunderbird < 68.3, Firefox ESR <     68.3, and Firefox < 71. (CVE-2019-17010)

  - Under certain conditions, when retrieving a document     from a DocShell in the antitracking code, a race     condition could cause a use-after-free condition and a     potentially exploitable crash. This vulnerability     affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-17011)

  - Mozilla developers reported memory safety bugs present     in Firefox 70 and Firefox ESR 68.2. Some of these bugs     showed evidence of memory corruption and we presume that     with enough effort some of these could have been     exploited to run arbitrary code. This vulnerability     affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-17012)

  - When using nested workers, a use-after-free could occur     during worker destruction. This resulted in a     potentially exploitable crash. This vulnerability     affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-17008)

  - The plain text serializer used a fixed-size array for     the number of  elements it could process; however it     was possible to overflow the static-sized array leading     to memory corruption and a potentially exploitable     crash. This vulnerability affects Thunderbird < 68.3,     Firefox ESR < 68.3, and Firefox < 71. (CVE-2019-17005)

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

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4216-2 advisory.

  - When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the     block size, a small out of bounds write could occur. This could have caused heap corruption and a     potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-11745)

  - Improper refcounting of soft token session objects could cause a use-after-free and crash (likely limited     to a denial of service). This vulnerability affects Firefox < 71. (CVE-2019-11756)

  - The plain text serializer used a fixed-size array for the number of <ol> elements it could process;
    however it was possible to overflow the static-sized array leading to memory corruption and a potentially     exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.
    (CVE-2019-17005)

  - When using nested workers, a use-after-free could occur during worker destruction. This resulted in a     potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-17008)

  - Under certain conditions, when checking the Resist Fingerprinting preference during device orientation     checks, a race condition could have caused a use-after-free and a potentially exploitable crash. This     vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71. (CVE-2019-17010)

  - Under certain conditions, when retrieving a document from a DocShell in the antitracking code, a race     condition could cause a use-after-free condition and a potentially exploitable crash. This vulnerability     affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71. (CVE-2019-17011)

  - Mozilla developers reported memory safety bugs present in Firefox 70 and Firefox ESR 68.2. Some of these     bugs showed evidence of memory corruption and we presume that with enough effort some of these could have     been exploited to run arbitrary code. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3,     and Firefox < 71. (CVE-2019-17012)

  - Mozilla developers reported memory safety bugs present in Firefox 70. Some of these bugs showed evidence     of memory corruption and we presume that with enough effort some of these could have been exploited to run     arbitrary code. This vulnerability affects Firefox < 71. (CVE-2019-17013)

  - If an image had not loaded correctly (such as when it is not actually an image), it could be dragged and     dropped cross-domain, resulting in a cross-origin information leak. This vulnerability affects Firefox <     71. (CVE-2019-17014)

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