Detail

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 the oldstable distribution (stretch), this problem has been fixed in version 1:2.2.27-3+deb9u5.

For the stable distribution (buster), this problem has been fixed in version 1:2.3.4.1-5+deb10u1.

We recommend that you upgrade your dovecot packages.
