USN-4202-1 fixed vulnerabilities in Thunderbird. After upgrading, Thunderbird
created a new profile for some users. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
It was discovered that a specially crafted S/MIME message with an inner
encryption layer could be displayed as having a valid signature in some
circumstances, even if the signer had no access to the encrypted message.
An attacker could potentially exploit this to spoof the message author.
(CVE-2019-11755)
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 cause a denial of service,
bypass security restrictions, bypass same-origin restrictions, conduct
cross-site scripting (XSS) attacks, or execute arbitrary code.
(CVE-2019-11757, CVE-2019-11758, CVE-2019-11759, CVE-2019-11760,
CVE-2019-11761, CVE-2019-11762, CVE-2019-11763, CVE-2019-11764)
A heap overflow was discovered in the expat library in Thunderbird. If a
user were tricked in to opening a specially crafted message, an attacker
could potentially exploit this to cause a denial of service, or execute
arbitrary code. (CVE-2019-15903)
