| Description: | Summary:
The remote host is missing an update for the 'thunderbird' package(s) announced via the USN-3927-1 advisory.
Vulnerability Insight:
It was discovered that Thunderbird allowed PAC files to specify that
requests to localhost are sent through the proxy to another server. If
proxy auto-detection is enabled, an attacker could potentially exploit
this to conduct attacks on local services and tools. (CVE-2018-18506)
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-2019-9788, CVE-2019-9790, CVE-2019-9791,
CVE-2019-9792, CVE-2019-9795, CVE-2019-9796, CVE-2019-9810, CVE-2019-9813)
A mechanism was discovered that removes some bounds checking for string,
array, or typed array accesses if Spectre mitigations have been disabled.
If a user were tricked in to opening a specially crafted website in a
