Arch Linux Security Advisory ASA-201912-1 ========================================= Severity: Critical Date : 2019-12-03 CVE-ID : CVE-2019-11745 CVE-2019-11756 CVE-2019-17005 CVE-2019-17008 CVE-2019-17009 CVE-2019-17010 CVE-2019-17011 CVE-2019-17012 CVE-2019-17013 CVE-2019-17014 Package : firefox Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1071 Summary ======= The package firefox before version 71.0-1 is vulnerable to multiple issues including arbitrary code execution, denial of service, information disclosure and privilege escalation. Resolution ========== Upgrade to 71.0-1. # pacman -Syu "firefox>=71.0-1" The problems have been fixed upstream in version 71.0. 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-2019-11756 (denial of service) A use-after-free vulnerability has been found in Firefox before 71.0 where improper reference counting of soft token session objects could cause a use-after-free and crash (likely limited to a denial of service). - 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-2019-17009 (privilege escalation) A privilege escalation vulnerability has been found in Firefox before 71.0. When running, the updater service wrote status and log files to an unrestricted location; potentially allowing an unprivileged process to locate and exploit a vulnerability in file handling in the updater service. - 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. - CVE-2019-17013 (arbitrary code execution) Several memory safety bugs have been found in Firefox before 71.0. 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. - CVE-2019-17014 (information disclosure) An information disclosure issue has been found in Firefox before 71.0 where, if an image had not loaded correctly (such as when it is not actually an image), it could be dragged and dropped cross-domain, resulting in a cross-origin information leak. Impact ====== A remote attacker can crash Firefox, access sensitive information, escalate privileges and execute arbitrary code on the affected host.
