DLA 1901-1: dovecot security update

Package : dovecot
Version : 1:2.2.13-12~deb8u7
CVE ID : CVE-2019-11500


Nick Roessler and Rafi Rubin discovered that the IMAP and ManageSieve
protocol parsers in the Dovecot email server do not properly validate
input (both pre- and post-login). A remote attacker can take advantage
of this flaw to trigger out of bounds heap memory writes, leading to
information leaks or potentially the execution of arbitrary code.

For Debian 8 "Jessie", this problem has been fixed in version
1:2.2.13-12~deb8u7.

We recommend that you upgrade your dovecot packages.
