[ASA-201710-19] thunderbird: multiple issues
Arch Linux Security Advisory ASA-201710-19 ========================================== Severity: Critical Date : 2017-10-12 CVE-ID : CVE-2017-7793 CVE-2017-7805 CVE-2017-7810 CVE-2017-7814 CVE-2017-7818 CVE-2017-7819 CVE-2017-7823 CVE-2017-7824 Package : thunderbird Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-441 Summary ======= The package thunderbird before version 52.4.0-1 is vulnerable to multiple issues including arbitrary code execution, access restriction bypass and cross-site scripting. Resolution ========== Upgrade to 52.4.0-1. # pacman -Syu "thunderbird>=52.4.0-1" The problems have been fixed upstream in version 52.4.0. Workaround ========== None. Description =========== - CVE-2017-7793 (arbitrary code execution) A use-after-free vulnerability can occur in the Fetch API of Thunderbird < 52.4, when the worker or the associated window are freed when still in use, resulting in a potentially exploitable crash. - CVE-2017-7805 (arbitrary code execution) A security issue has been found in Thunderbird < 52.4. During TLS 1.2 exchanges, handshake hashes are generated which point to a message buffer. This saved data is used for later messages but in some cases, the handshake transcript can exceed the space available in the current buffer, causing the allocation of a new buffer. This leaves a pointer pointing to the old, freed buffer, resulting in a use-after-free when handshake hashes are then calculated afterwards. This can result in a potentially exploitable crash. - CVE-2017-7810 (arbitrary code execution) Mozilla developers and community members Christoph Diehl, Jan de Mooij, Jason Kratzer, Randell Jesup, Tom Ritter, Tyson Smith, and Sebastian Hengst reported memory safety bugs present in Firefox <= 55, Firefox ESR <= 52.3, and Thunderbird <= 52.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. - CVE-2017-7814 (access restriction bypass) A security issue has been found in Thunderbird < 52.4. File downloads encoded with blob: and data: URL elements bypassed normal file download checks though the Phishing and Malware Protection feature and its block lists of suspicious sites and files. This would allow malicious sites to lure users into downloading executables that would otherwise be detected as suspicious. - CVE-2017-7818 (arbitrary code execution) A use-after-free vulnerability can occur when manipulating arrays of Accessible Rich Internet Applications (ARIA) elements within containers through the DOM, in Thunderbird < 52.4. This results in a potentially exploitable crash. - CVE-2017-7819 (arbitrary code execution) A use-after-free vulnerability can occur in design mode when image objects are resized if objects referenced during the resizing have been freed from memory, in Thunderbird < 52.4. This results in a potentially exploitable crash. - CVE-2017-7823 (cross-site scripting) The content security policy (CSP) sandbox directive in Thunderbird < 52.4 did not create a unique origin for the document, causing it to behave as if the allow-same-origin keyword were always specified. This could allow a Cross-Site Scripting (XSS) attack to be launched from unsafe content. - CVE-2017-7824 (arbitrary code execution) A buffer overflow occurs when drawing and validating elements with the ANGLE graphics library, used for WebGL content in Thunderbird < 52.4. This is due to an incorrect value being passed within the library during checks and results in a potentially exploitable crash. Impact ====== A remote attacker can bypass security measures like the phishing and malware protection or a content security policy, and execute arbitrary code on the affected host.
