  script_tag(name:"insight", value:"CVE-2018-12377: Use-after-free in refresh driver timers
A use-after-free vulnerability 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: Use-after-free in IndexedDB
A use-after-free vulnerability 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-2018-18499: Same-origin policy violation using meta refresh and performance.getEntries to steal cross-origin URLs
A same-origin policy violation allowing the theft of cross-origin URL entries when using a <meta> meta http-equiv='refresh' on a page to cause a redirection to another site using performance.getEntries(). This is a same-origin policy violation and could allow for data theft.

CVE-2018-12379: Out-of-bounds write with malicious MAR file
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-2017-16541: Proxy bypass using automount and autofs
Browser proxy settings can be bypassed by using the automount feature with autofs to create a mount point on the local file system. Content can be loaded from this mounted file system directly using a file: URI, bypassing configured proxy settings. Note: this issue only affects OS X in default configurations. On Linux systems, autofs must be installed for the vulnerability to occur and Windows is not affected.

CVE-2018-12383: Setting a master password post-Firefox 58 does not delete unencrypted previously stored passwords
If a user saved passwords before Firefox 58 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 Firefox 58. The new master password ...
