Arch Linux Security Advisory ASA-201912-2 ========================================= Severity: Critical Date : 2019-12-06 CVE-ID : CVE-2019-11745 CVE-2019-17005 CVE-2019-17008 CVE-2019-17010 CVE-2019-17011 CVE-2019-17012 Package : thunderbird Type : arbitrary code execution Remote : Yes Link : https://security.archlinux.org/AVG-1072 Summary ======= The package thunderbird before version 68.3.0-1 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 68.3.0-1. # pacman -Syu "thunderbird>=68.3.0-1" The problems have been fixed upstream in version 68.3.0. Workaround ========== None. Description =========== - CVE-2019-11745 (arbitrary code execution) An out-of-bounds write vulnerability has been found in the NSS component of Firefox before 71.0 and Thunderbird before 68.3. When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the block size, a small out of bounds write could occur. This could have caused heap corruption and a potentially exploitable crash. - CVE-2019-17005 (arbitrary code execution) An out-of-bounds write vulnerability has been found in Firefox before 71.0 and Thunderbird before 68.3 where the plain text serializer used a fixed-size array for the number of elements it could process; however it was possible to overflow the static-sized array leading to memory corruption and a potentially exploitable crash. - CVE-2019-17008 (arbitrary code execution) A use-after-free vulnerability has been found in Firefox before 71.0 and Thunderbird before 68.3. When using nested workers, a use-after- free could occur during worker destruction. This resulted in a potentially exploitable crash. - CVE-2019-17010 (arbitrary code execution) A use-after-free vulnerability has been found in Firefox before 71.0 and Thunderbird before 68.3. Under certain conditions, when checking the Resist Fingerprinting preference during device orientation checks, a race condition could have caused a use-after-free and a potentially exploitable crash. - CVE-2019-17011 (arbitrary code execution) A use-after-free vulnerability has been found in Firefox before 71.0 and Thunderbird before 68.3. Under certain conditions, when retrieving a document from a DocShell in the antitracking code, a race condition could cause a use-after-free condition and a potentially exploitable crash. - CVE-2019-17012 (arbitrary code execution) Several memory safety bugs have been found in Firefox before 71.0 and Thunderbird before 68.3. 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 execute arbitrary code on the affected host.
