Arch Linux Security Advisory ASA-201910-15 ========================================== Severity: Critical Date : 2019-10-26 CVE-ID : CVE-2019-11757 CVE-2019-11759 CVE-2019-11760 CVE-2019-11761 CVE-2019-11762 CVE-2019-11763 CVE-2019-11764 CVE-2019-15903 Package : thunderbird Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1054 Summary ======= The package thunderbird before version 68.2.0-1 is vulnerable to multiple issues including arbitrary code execution, access restriction bypass, denial of service, insufficient validation and same-origin policy bypass. Resolution ========== Upgrade to 68.2.0-1. # pacman -Syu "thunderbird>=68.2.0-1" The problems have been fixed upstream in version 68.2.0. Workaround ========== None. Description =========== - CVE-2019-11757 (arbitrary code execution) A use-after-free issue has been found in the IndexedDB component of Firefox before 70.0 and Thunderbird before 68.2. When storing a value in IndexedDB, the value's prototype chain is followed and it was possible to retain a reference to a locale, delete it, and subsequently reference it. - CVE-2019-11759 (arbitrary code execution) A stack-based buffer overflow has been found in the HKDF output of Firefox before 70.0 and Thunderbird before 68.2. An attacker could have caused 4 bytes of HMAC output to be written past the end of a buffer stored on the stack. - CVE-2019-11760 (arbitrary code execution) A fixed-size stack buffer overflow has been found in nrappkit, in the WebRTC signaling code of Firefox before 70.0 and Thunderbird before 68.2. - CVE-2019-11761 (access restriction bypass) An issue has been found in Firefox before 70.0 and Thunderbird before 68.2, where 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. - CVE-2019-11762 (same-origin policy bypass) A same-origin policy bypass has been found in Firefox before 70.0 and Thunderbird before 68.2 where, 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. - CVE-2019-11763 (insufficient validation) An issue has been found in Firefox before 70.0 and Thunderbird before 68.2, where failure to correctly handle null bytes when processing HTML entities resulted in 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. - CVE-2019-11764 (arbitrary code execution) Several memory safety bugs have been found in Firefox before 70.0 and Thunderbird before 68.2. 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-2019-15903 (denial of service) A security issue has been found in libexpat before 2.2.8, where 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 Impact ====== A remote attacker could crash Thunderbird, bypass security measures or execute arbitrary code.
