Arch Linux Security Advisory ASA-202003-11 ========================================== Severity: Critical Date : 2020-03-16 CVE-ID : CVE-2019-20503 CVE-2020-6805 CVE-2020-6806 CVE-2020-6807 CVE-2020-6811 CVE-2020-6812 CVE-2020-6814 Package : thunderbird Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1115 Summary ======= The package thunderbird before version 68.6.0-1 is vulnerable to multiple issues including arbitrary code execution, arbitrary command execution and information disclosure. Resolution ========== Upgrade to 68.6.0-1. # pacman -Syu "thunderbird>=68.6.0-1" The problems have been fixed upstream in version 68.6.0. Workaround ========== None. Description =========== - CVE-2019-20503 (information disclosure) An out-of-bounds read has been found in Firefox before 74 and Thunderbird before 68.6. 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-2020-6805 (arbitrary code execution) A use-after-free issue has been found in Firefox before 74 and Thunderbird before 68.6. 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-2020-6806 (arbitrary code execution) A state confusion issue has been found in Firefox before 74 and Thunderbird before 68.6, in BodyStream::OnInputStreamReady. 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-2020-6807 (arbitrary code execution) A use-after-free issue has been found in Firefox before 74 and Thunderbird before 68.6, in cubeb during stream destruction. 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-2020-6811 (arbitrary command execution) A security issue has been found in Firefox before 74 and Thunderbird before 68.6, where 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-2020-6812 (information disclosure) An information disclosure issue has been found in Firefox before 74 and Thunderbird before 68.6. 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-2020-6814 (arbitrary code execution) Several memory safety and script safety bugs have been found in Firefox before 74, Firefox ESR before 68.6 and Thunderbird before 68.6. Some of these bugs showed evidence of memory corruption or escalation of privilege and Mozilla presumes that with enough effort some of these could have been exploited to run arbitrary code. Impact ====== A remote attacker can access sensitive information and execute arbitrary commands and code on the affected host.
