Updated chromium-browser-stable packages fix security vulnerabilities
Chromium-browser 80.0.3987.122 fixes security issues:
Multiple flaws were found in the way Chromium 79.0.3945.130 processes various types of web content, where loading a web page containing malicious content could cause Chromium to crash, execute arbitrary code, or disclose sensitive information. (CVE-2020-6381, CVE-2020-6382, CVE-2020-6383, CVE-2020-6384, CVE-2020-6385, CVE-2020-6386, CVE-2020-6387, CVE-2020-6388, CVE-2020-6389, CVE-2020-6390, CVE-2020-6391, CVE-2020-6392, CVE-2020-6393, CVE-2020-6394, CVE-2020-6395, CVE-2020-6396, CVE-2020-6397, CVE-2020-6398, CVE-2020-6399, CVE-2020-6400, CVE-2020-6401, CVE-2020-6402, CVE-2020-6403, CVE-2020-6404, CVE-2020-6405, CVE-2020-6406, CVE-2020-6407, CVE-2020-6408, CVE-2020-6409, CVE-2020-6410, CVE-2020-6411, CVE-2020-6412, CVE-2020-6413, CVE-2020-6414, CVE-2020-6415, CVE-2020-6416, CVE-2020-6418, CVE-2019-18197, CVE-2019-19923, CVE-2019-19925, CVE-2019-19926)
Upstream chromium 80.0.3987.122 also includes a fix for an integer overflow issue in ICU. Since the chromium-browser-stable package is linked against the icu packages instead of using the ICU source code bundled with chromium upstream, this issue is fixed in the icu package.
