Critical: thunderbird security update (Amazon Linux 2)

Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2018-18498: A potential vulnerability leading to an integer overflow can occur during buffer size calculations for images when a raw value is used instead of the checked value. This leads to a possible out-of-bounds write. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64. 1658402: CVE-2018-18498 Mozilla: Integer overflow when calculating buffer sizes for images CVE-2018-18494: A same-origin policy violation allowing the theft of cross-origin URL entries when using the Javascript location property to cause a redirection to another site using performance.getEntries(). This is a same-origin policy violation and could allow for data theft. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64. 1658401: CVE-2018-18494 Mozilla: Same-origin policy violation using location attribute and performance.getEntries to steal cross-origin URLs CVE-2018-18493: A buffer overflow can occur in the Skia library during buffer offset calculations with hardware accelerated canvas 2D actions due to the use of 32-bit calculations instead of 64-bit. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64. 1658400: CVE-2018-18493 Mozilla: Buffer overflow in accelerated 2D canvas with Skia CVE-2018-18492: A use-after-free vulnerability can occur after deleting a selection element due to a weak reference to the select element in the options collection. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64. 1658399: CVE-2018-18492 Mozilla: Use-after-free with select element CVE-2018-17466: Incorrect texture handling in Angle in Google Chrome prior to 70.0.3538.67 allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page. 1640102: CVE-2018-17466 chromium-browser, firefox: Memory corruption in Angle CVE-2018-12405: Mozilla developers and community members reported memory safety bugs present in Firefox 63 and Firefox ESR 60.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64. 1658397: CVE-2018-12405 Mozilla: Memory safety bugs fixed in Firefox 64 and Firefox ESR 60.4
