thunderbird vulnerabilities

Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially crafted message, an attacker could potentially exploit these to read uninitialized memory, cause a denial of service via application crash, or execute arbitrary code. (CVE-2017-5429, CVE-2017-5430, CVE-2017-5436, CVE-2017-5443, CVE-2017-5444, CVE-2017-5445, CVE-2017-5446, CVE-2017-5447, CVE-2017-5461, CVE-2017-5467)

Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit these to spoof the addressbar contents, conduct cross-site scripting (XSS) attacks, cause a denial of service via application crash, or execute arbitrary code. (CVE-2017-5432, CVE-2017-5433, CVE-2017-5434, CVE-2017-5435, CVE-2017-5437, CVE-2017-5438, CVE-2017-5439, CVE-2017-5440, CVE-2017-5441, CVE-2017-5442, CVE-2017-5449, CVE-2017-5451, CVE-2017-5454, CVE-2017-5459, CVE-2017-5460, CVE-2017-5464, CVE-2017-5465, CVE-2017-5466, CVE-2017-5469, CVE-2016-10195, CVE-2016-10196, CVE-2016-10197)

A flaw was discovered in the DRBG number generation in NSS. If an attacker were able to perform a machine-in-the-middle attack, this flaw could potentially be exploited to view sensitive information. (CVE-2017-5462)
