This update for seamonkey fixes the following issues:

Update to 2.53.18.1:

* Update the NSS library to the latest esr 115 version for the final
2.53.18.1 release.
* SeaMonkey 2.53.18.1 uses the same backend as Firefox and contains
the relevant Firefox 60.8 security fixes.
* SeaMonkey 2.53.18.1 shares most parts of the mail and news code
with Thunderbird. Please read the Thunderbird 60.8.0 release notes
for specific security fixes in this release.
* Additional important security fixes up to Current Firefox 115.7
and Thunderbird 115.7 ESR plus many enhancements have been
backported. We will continue to enhance SeaMonkey security in
subsequent 2.53.x beta and release versions as fast as we are able to.
