Arch Linux Security Advisory ASA-201905-8 ========================================= Severity: Critical Date : 2019-05-23 CVE-ID : CVE-2019-5798 CVE-2019-7317 CVE-2019-9800 CVE-2019-9816 CVE-2019-9817 CVE-2019-9819 CVE-2019-11691 CVE-2019-11692 CVE-2019-11693 CVE-2019-11698 CVE-2019-18511 Package : thunderbird Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-965 Summary ======= The package thunderbird before version 60.7.0-1 is vulnerable to multiple issues including arbitrary code execution, access restriction bypass, same-origin policy bypass, information disclosure and denial of service. Resolution ========== Upgrade to 60.7.0-1. # pacman -Syu "thunderbird>=60.7.0-1" The problems have been fixed upstream in version 60.7.0. Workaround ========== None. Description =========== - CVE-2019-5798 (information disclosure) An out-of-bounds read has been found in the Skia component of the chromium browser before 73.0.3683.75 and Thunderbird before 60.7.0. - CVE-2019-7317 (denial of service) png_image_free in png.c in libpng 1.6.36 has a use-after-free because png_image_free_function is called under png_safe_execute. - CVE-2019-9800 (arbitrary code execution) Several memory safety bugs have been found in Firefox before 67.0 and Thunderbird before 60.7.0. Some of these bugs showed evidence of memory corruption and Mozilla presumes that with enough effort some of these could be exploited to run arbitrary code. - CVE-2019-9816 (access restriction bypass) A possible vulnerability exists in Firefox before 67.0 and Thunderbird before 60.7.0, where type confusion can occur when manipulating JavaScript objects in object groups, allowing for the bypassing of security checks within these groups. Note that this vulnerability has only been demonstrated with UnboxedObjects, which are disabled by default on all supported releases. - CVE-2019-9817 (same-origin policy bypass) In Firefox before 67.0 and Thunderbird before 60.7.0, images from a different domain can be read using a canvas object in some circumstances. This could be used to steal image data from a different site in violation of same-origin policy. - CVE-2019-9819 (arbitrary code execution) A vulnerability where a JavaScript compartment mismatch can occur in Firefox before 67.0 and Thunderbird before 60.7.0, while working with the fetch API, resulting in a potentially exploitable crash. - CVE-2019-11691 (arbitrary code execution) A use-after-free vulnerability can occur in Firefox before 67.0 and Thunderbird before 60.7.0, when working with XMLHttpRequest (XHR) in an event loop, causing the XHR main thread to be called after it has been freed. This results in a potentially exploitable crash. - CVE-2019-11692 (arbitrary code execution) A use-after-free vulnerability can occur in Firefox before 67.0 and Thunderbird before 60.7.0, when listeners are removed from the event listener manager while still in use, resulting in a potentially exploitable crash. - CVE-2019-11693 (arbitrary code execution) The bufferdata function in WebGL in Firefox before 67.0 and Thunderbird before 60.7.0 is vulnerable to a buffer overflow with specific graphics drivers on Linux. This could result in malicious content freezing a tab or triggering a potentially exploitable crash. - CVE-2019-11698 (information disclosure) If a crafted hyperlink is dragged and dropped to the bookmark bar or sidebar in Firefox before 67.0 or Thunderbird before 60.7.0, and the resulting bookmark is subsequently dragged and dropped into the web content area, an arbitrary query of a user's browser history can be run and transmitted to the content page via drop event data. This allows for the theft of browser history by a malicious site. - CVE-2019-18511 (same-origin policy bypass) An issue has been found in Thunderbird before 60.7.0, where cross- origin images can be read from a canvas element in violation of the same-origin policy using the transferFromImageBitmap method. Impact ====== A remote attacker can crash Thunderbird, access sensitive information, bypass security measures or execute arbitrary code on the affected host.
