Security Fix(es):
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: When removing data about an origin whose tab was recently closed, a use-after-free could occur in the Quota manager, resulting in a potentially exploitable crash.(CVE-2020-6805)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: By carefully crafting promise resolutions, it was possible to cause an out-of-bounds read off the end of an array resized during script execution. This could have led to memory corruption and a potentially exploitable crash.(CVE-2020-6806)
thunderbird: When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer does not escape < and > characters. Because the resulting string is pasted directly into the text node of the element this does not result in a direct injection into the webpage; however, if a webpage subsequently copies the node's innerHTML, assigning it to another innerHTML, this would result in an XSS vulnerability. Two WYSIWYG editors were identified with this behavior, more may exist. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72.(CVE-2019-17022)
thunderbird: When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer incorrectly rewrites a @namespace rule. This could allow for injection into certain types of websites resulting in data exfiltration. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72.(CVE-2019-17016)
thunderbird: Due to a missing case handling object types, a type confusion vulnerability could occur, resulting in a crash. We presume that with enough effort that it could be exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72.(CVE-2019-17017)
thunderbird: Mozilla developers reported memory safety bugs present in Firefox 71 and Firefox ESR 68.3. 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 ESR < 68.4 and Firefox < 72.(CVE-2019-17024)
thunderbird: Incorrect alias information in IonMonkey JIT compiler for setting array elements could lead to a type confusion. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects Firefox ESR < 68.4.1, Thunderbird < 68.4.1, and Firefox < 72.0.1.(CVE-2019-17026)
thunderbird: When processing an email message with an ill-formed envelope, Thunderbird could read data from a random memory location. This vulnerability affects Thunderbird < 68.5.(CVE-2020-6793)
thunderbird: When processing a message that contains multiple S/MIME signatures, a bug in the MIME processing code caused a null pointer dereference, leading to an unexploitable crash. This vulnerability affects Thunderbird < 68.5.(CVE-2020-6795)
thunderbird: When deriving an identifier for an email message, uninitialized memory was used in addition to the message contents. This vulnerability affects Thunderbird < 68.5.(CVE-2020-6792)
thunderbird: If a template tag was used in a select tag, the parser could be confused and allow JavaScript parsing and execution when it should not be allowed. A site that relied on the browser behaving correctly could suffer a cross-site scripting vulnerability as a result. In general, this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but is potentially a risk in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5.(CVE-2020-6798)
thunderbird: Mozilla developers and community members reported memory safety bugs present in Firefox 72 and Firefox ESR 68.4. 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. In general, these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5.(CVE-2020-6800)
thunderbird: If a user saved passwords before Thunderbird 60 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Thunderbird 60. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations. This vulnerability affects Thunderbird < 68.5.(CVE-2020-6794)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP method of a request, which can be controlled by the website. If a user used the 'Copy as Curl' feature and pasted the command into a terminal, it could have resulted in command injection and arbitrary command execution.(CVE-2020-6811)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: The inputs to `sctp_load_addresses_from_init` are verified by `sctp_arethere_unrecognized_parameters`; however, the two functions handled parameter bounds differently, resulting in out of bounds reads when parameters are partially outside a chunk.(CVE-2019-20503)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: The first time AirPods are connected to an iPhone, they become named after the user's name by default (e.g. Jane Doe's AirPods.) Websites with camera or microphone permission are able to enumerate device names, disclosing the user's name. To resolve this issue, Firefox added a special case that renames devices containing the substring 'AirPods' to simply 'AirPods'.(CVE-2020-6812)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: When a device was changed while a stream was about to be destroyed, the `stream-reinit` task may have been executed after the stream was destroyed, causing a use-after-free and a potentially exploitable crash.(CVE-2020-6807)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: Mozilla developers and community members reported memory safety bugs present in Firefox 73 and Firefox ESR 68.5. 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.(CVE-2020-6814)
thunderbird: A flaw was found in Mozilla Firefox. A race condition can occur while running the nsDocShell destructor causing a use-after-free memory issue. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.(CVE-2020-6819)
thunderbird: A flaw was found in Mozilla's Firefox. A race condition can occur when handling a ReadableStream causing a use-after-free memory issue. The highest threat from this vulnerability are to data confidentiality and integrity as well as system availability.(CVE-2020-6820)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: When reading from areas partially or fully outside the source resource with WebGL's copyTexSubImage method, the specification requires the returned values be zero. Previously, this memory was uninitialized, leading to potentially sensitive data disclosure.(CVE-2020-6821)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: On 32-bit builds, an out of bounds write could have occurred when processing an image larger than 4 GB in GMPDecodeData. It is possible that with enough effort this could have been exploited to run arbitrary code.(CVE-2020-6822)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: Mozilla developers reported memory safety bugs present in Firefox 74 and Firefox ESR 68.6. 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.(CVE-2020-6825)
thunderbird: A flaw was found in Mozilla Firefox and Thunderbird. When running shutdown code for Web Worker, a race condition occurs leading to a use-after-free memory flaw that could lead to an exploitable crash. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.(CVE-2020-12387)
thunderbird: A flaw was found in Mozilla Firefox and Thunderbird. When parsing and validating SCTP chunks in WebRTC a memory buffer overflow could occur leading to memory corruption and an exploitable crash. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.(CVE-2020-6831)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP POST data of a request, which can be controlled by the website. If a user used the 'Copy as cURL' feature and pasted the command into a terminal, it could have resulted in the disclosure of local files.(CVE-2020-12392)
thunderbird: Memory safety flaws were found in Mozilla Firefox and Thunderbird. Memory corruption that an attacker could leverage with enough effort, could allow arbitrary code to run. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.(CVE-2020-12395)
thunderbird: By encoding Unicode whitespace characters within the From email header, an attacker can spoof the sender email address that Thunderbird displays. This vulnerability affects Thunderbird < 68.8.0.(CVE-2020-12397)
thunderbird: bugfix
ksh: A flaw was found in the way ksh evaluates certain environment variables. An attacker could use this flaw to override or bypass environment restrictions to execute shell commands. Services and applications that allow remote unauthenticated attackers to provide one of those environment variables could allow them to exploit this issue remotely.(CVE-2019-14868)
ksh: bugfix
