Critical vulnerability in the Dovecot IMAP server

Posted on

In the corrective releases of the POP3/IMAP4 server Dovecot 2.3.7.2 and 2.2.36.4, as well as in the add-on Pigeonhole 0.5.7.2 and 0.4.24.2, a critical vulnerability (CVE-2019-11500) was addressed that allows for data to be written outside the allocated buffer by sending specially crafted requests via the IMAP or ManageSieve protocols. This issue can be exploited even before authentication is completed. A working exploit has yet to be prepared, but […]

Perl developers are considering renaming the Perl 6 language.

Posted on

Perl language developers are discussing the possibility of evolving Perl 6 under a different name. Initially, Perl 6 was suggested to be renamed to "Camelia," but then the focus shifted to the name "Raku" proposed by Larry Wall, which is shorter, associates with the existing perl6 compiler "Rakudo," and doesn’t conflict with other projects in search engines. The name Camelia was proposed as it is an existing name of a mascot and […]

Tarantool Cartridge: sharding a Lua backend in three lines

Posted on

At Mail.ru Group, we have Tarantool — an application server on Lua that also acts as a database (or vice versa?). It's fast and great, but even the capabilities of a single server are not limitless. Vertical scaling isn't a panacea either, so Tarantool offers tools for horizontal scaling — the vshard module [1]. It allows for sharding […]

Next-generation billing architecture: transformation with a transition to Tarantool

Posted on

Why would a corporation like MegaFon use Tarantool in billing? It may seem that usually a vendor comes in, brings a big box, plugs it into a socket — and that’s billing! Once upon a time, that was true, but now it’s archaic, and such dinosaurs have either gone extinct or are dying off. Originally, billing was a system for invoicing — a calculator. In modern telecom, it is a system for automating the entire lifecycle of interaction with the subscriber […]
