Summary
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,
or execute arbitrary code. (CVE-2018-12376, CVE-2018-12377,
CVE-2018-12378)
It was discovered that if a user saved passwords before Thunderbird 58 and
then later set a master password, an unencrypted copy of these passwords
would still be accessible. A local user could exploit this to obtain
sensitive information. (CVE-2018-12383)
A crash was discovered in TransportSecurityInfo used for SSL, which could
be triggered by data stored in the local cache directory. An attacker
could potentially exploit this in combination with another vulnerability
that allowed them to write data to the cache, to execute arbitrary code.
(CVE-2018-12385)
