Arch Linux Security Advisory ASA-201810-13 ========================================== Severity: Critical Date : 2018-10-18 CVE-ID : CVE-2018-12376 CVE-2018-12377 CVE-2018-12378 CVE-2018-12379 CVE-2018-12383 CVE-2018-12385 Package : thunderbird Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-782 Summary ======= The package thunderbird before version 60.2.1-1 is vulnerable to multiple issues including arbitrary code execution and information disclosure. Resolution ========== Upgrade to 60.2.1-1. # pacman -Syu "thunderbird>=60.2.1-1" The problems have been fixed upstream in version 60.2.1. Workaround ========== None. Description =========== - CVE-2018-12376 (arbitrary code execution) Several memory safety bugs have been found in Thunderbird versions prior to 60.2.1. - CVE-2018-12377 (arbitrary code execution) A use-after-free vulnerability has been found in Thunderbird versions prior to 60.2.1, which can occur when refresh driver timers are refreshed in some circumstances during shutdown when the timer is deleted while still in use. This results in a potentially exploitable crash. - CVE-2018-12378 (arbitrary code execution) A use-after-free vulnerability has been found in Thunderbird versions prior to 60.2.1, which can occur when an IndexedDB index is deleted while still in use by JavaScript code that is providing payload values to be stored. This results in a potentially exploitable crash. - CVE-2018-12379 (arbitrary code execution) A security issue has been found in Thunderbird versions prior to 60.2.1. When the Mozilla Updater opens a MAR format file which contains a very long item filename, an out-of-bounds write can be triggered, leading to a potentially exploitable crash. This requires running the Mozilla Updater manually on the local system with the malicious MAR file in order to occur. - CVE-2018-12383 (information disclosure) A security issue has been found in Thunderbird versions prior to 60.2.1. If a user saved passwords before the move to a new password format 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. 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-2018-12385 (arbitrary code execution) A security issue has been found in Thunderbird versions prior to 60.2.1. A potentially exploitable crash in TransportSecurityInfo used for SSL can be triggered by data stored in the local cache in the user profile directory. This issue is only exploitable in combination with another vulnerability allowing an attacker to write data into the local cache or from locally installed malware. Impact ====== A remote attacker can access sensitive information or execute arbitrary code on the affected host.
