Arch Linux Security Advisory ASA-202002-9 ========================================= Severity: Critical Date : 2020-02-13 CVE-ID : CVE-2020-6792 CVE-2020-6793 CVE-2020-6794 CVE-2020-6795 CVE-2020-6798 CVE-2020-6800 Package : thunderbird Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1099 Summary ======= The package thunderbird before version 68.5.0-1 is vulnerable to multiple issues including arbitrary code execution, cross-site scripting, denial of service and information disclosure. Resolution ========== Upgrade to 68.5.0-1. # pacman -Syu "thunderbird>=68.5.0-1" The problems have been fixed upstream in version 68.5.0. Workaround ========== None. Description =========== - CVE-2020-6792 (information disclosure) An information disclosure issue has bee found in Thunderbird before 68.5. When deriving an Message ID identifier for an email message, uninitialized memory was used in addition to the message contents. - CVE-2020-6793 (information disclosure) An out-of-bounds read has been found in Thunderbird before 68.5, when processing an e-mail message with an ill-formed envelope. - CVE-2020-6794 (information disclosure) It has been found that setting a master password post-Thunderbird 52 does not delete unencrypted previously stored passwords before Thunderbird 68.5. 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. - CVE-2020-6795 (denial of service) A null-pointer dereference has been found in Thunderbird before 68.5, when processing a message that contains multiple S/MIME signatures. - CVE-2020-6798 (cross-site scripting) An incorrect parsing of template could result in Javascript injection in Firefox before 73.0 and Thunderbird before 68.5. If a <template> tag was used in a <select%gt; 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. - CVE-2020-6800 (arbitrary code execution) Several memory safety bugs have been found in Firefox before 73.0 and Thunderbird before 68.5. Some of these bugs showed evidence of memory corruption 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, bypass security measures, crash the application or execute arbitrary code.
